Clogs can be incredibly frustrating. Normally when you find out you have a clogged printhead, it’s because you’re right in the middle of printing something important. It’s one of those problems that you never ask for. It just seems to throw itself in your lap without warning, and then taunts you in your efforts to fix it.

The printhead is the mechanism of your printer (or inkjet cartridge), where the ink actually comes out.

For the most part, printhead clogs can be normally be flushed out with a couple of “head cleaning” cycles. A head cleaning cycle is a built-in function of your printer. It’s a specialized routine meant to address this type of problem.

This “cleaning cycle” works by sending a strong ‘print signal’ to your printer, while at the same time drawing a small vacuum from underneath. The combination of these two steps works in an attempt to suck out clogged ink from the printhead. From my experience, you’ll probably need to run between 3 and 5 cycles to fully clear a clog.

The location of the head cleaning cycle proceedure varies for each printer brand, so refer to your printer owner’s manual for specific instructions to find yours. Check the index first.

If you don’t have your owner’s manual anymore, you can check our your printer manufacturers website. Most likely, they will have your printer manual online.

There are times however, when a few standard head cleaning routines don’t seem to solve the problem. A stubborn printhead clog like this can be persistant enough to make you want to rip out your hair.

For times like these, you’ll need to pull out the big guns!

For stubborn inkjet printhead clogs, there are various cleaners out there specifically for this purpose. These cleaners are formulated to disolve dried or “gummy” ink which may have accumulated from infrequent printer use, or even just a general build-up over time.

I personally brought an old printer “back from the dead” using a product called ‘Clog Buster’. It was a printer I had purchased off of eBay which apparently hadn’t been used in awhile. I spent a few hours trying to revive the printer, and ‘Clog Buster’ was the only thing that worked when nothing else did.

The only downside with using a cleaning product like this however, is that you usually don’t have it in your immediate possession when the clog hits. Unless you have some already on hand, you’ll have to wait for it to be shipped to you. In the meantime, your printing project will have to remain on pause until it arrives.

(But maybe I can help…)

The good news is that you MAY be able to solve the problem using some basic household products. In fact, Windex glass cleaner can actually work well for dissolving dried ink. What’s the secret ingredient?

Ammonia.

Tough printhead clogs can usually be brought into submission by soaking the printhead in a solution of 50/50% ammonia and distilled water.

A important word of warning… Ammonia is potent and powerful stuff. When working with ammonia, always make sure you’ve got adequate ventilation, and avoid mixing it with other chemicals. Very important.

So, if your printhead is located on the inkjet cartridge itself, you’ll want to soak the printhead in the 50/50 solution for an hour or two.

If the printhead unit is located inside your inkjet printer itself, then you’ll first need to remove the inkjet cartridges. After those are removed, put some of the solution into the top of the printhead (directly into the nozzle holes) and let it sit a few hours. Go ahead and put a little more into the printhead resting seat. (This is the rubber rectangle part that seals off the printhead unit while the carriage is in it’s resting position.)

If this initial soaking doesn’t work, then repeat another time using 100% ammonia for up to one hour. Afterward, make sure to rinse completely with distilled water.

If the clog doesn’t immediately clear, go ahead and let the printer sit overnight and try it again the next day. Sometimes the clog will breakdown slowly and release later as the ammonia takes it’s toll.

Finally, for those of you wondering about the effectiveness of using alcohol to unclog cartridges and printhead — here’s a quick note…

Alcohol won’t work as well as ammonia, but may work better than a few cleaning cycles. The downside is that alcohol may actually dry out the plastics and metals in the printhead. This could actually increase the chances of clogging later on down the road. So try to avoid alcohol if possible.

Money saving tip #1: Choose the correct print quality
When you print a document, you can choose various print qualities. Generally, the higher quality you choose, the more ink your printer will use. Not to mention that higher qualities take longer, as well. For many documents, you can change the print quality to the lower quality setting. Depending on your printer, the low quality setting might be called “draft”, “low quality”, “quick”, etc.

Here is how to change the print quality when you’re printing a document. Once you click print, a box will pop up. Select the printer you wish to use, then click “Preferences”. Another window will then pop up. What the window looks like will depend on what printer you’re using, but most of them will look at least somewhat similiar to each other. Choose your print quality, then click OK.

Note: You will not want to use the low quality setting for and of the following documents:
1: Adobe PDF files
2: Any file that you will want to copy, fax, or scan later
3: Most images
4: Any document that you need a sharp, quality print on

Money saving tip #2: Shop around for the best deal
If your printer is like most, it pops up a window when your ink is low, and gives you a button to buy replacement ink cartridges. Instead of buying your ink via clicking on that button, try shopping around for your replacement ink cartridges. There are many places that offer substantial discounts on ink, and you could save some money, just by visiting http://www.ink-guide.com

Also, keep in mind that your local office supply store will likely be an expensive source of ink. You’ll do much better shopping for replacement ink catridges online.

Money saving tip #3: Consider buying another brand of ink
Just because your printer was made by XYZ Company doesn’t mean that you have to buy ink from XYZ Company. You can shop around for different brands of ink cartridges, and you might save some money. You may not want to buy generic ink, but at least check out the other brand names of ink cartridges. Just be sure that the ink cartridge you buy says on the label that it will fit your printer.

Money saving tip #4: If all else fails, buy a laser printer
If you use a fair number of ink cartridges, you might want to consider buying a laser printer. Laser printers use toner (like a copy machine), instead of ink cartridges. Toner for a laser printer costs about a quarter as much as for an inkjet printer (per sheet printed).

The draw back to laser printers is that they are often more expensive than inkjet printers. I have a bottom of the line Dell black and white Laser printer, and I’ve been very pleased with it. We bought it for less than two hundred dollars. Based on the money we’ve saved on replacement ink cartridges, buying it was a good decision. However, it would only make financial sense to buy a laser printer if you printed quite a few documents every day.

I hope that these tips will help you save some money on your printer cartridges!

It is no longer a case of “a printer is a printer”. Printers are now designed to be good in a particular area rather than a “Jack-of-all trades”, which will do everything.

An often overlooked issue, is the very serious consideration of cost of ownership, which is all about of how much it will cost to keep your printer running (see below). So making that decision on which printer to go for can be a seriously arduous task, especially if you are keen to buy a printer that is not only affordable to buy but also cheap to run.

So here is the information that you need to know and consider, but no one tells you! We have not expanded on which printer is the best at any given time because models constantly change and you can find that information in any current glossy PC magazine off the shelf. Instead, here you will find the good, bad and ugly bits from the different types of printers available so you can make an informed decision yourself.
Inkjet Technology

Inkjet printers form images by spraying tiny droplets of liquid ink onto paper. The size and precision of the dots of ink and the type and quality of the ink itself govern how good the print quality is. A quality inkjet printer can produce very near photo-quality images using specialist photo coated paper. In general there are two types of inkjet printers, those with the printhead built into the printer like Epson, Brother etc and those where the printhead is actually on the ink cartridge like HP and Lexmark. There are many arguments for and against both technologies, but in our experience we have found both to be very good, the major difference seems to be that the cost of running a printer using the “printhead” type ink cartridge is usually higher.
Inkjet ink is specially formulated for specific printer models and their purpose, much technology is involved in the development of these inks to improve print quality, longevity, drying speeds and printing speeds etc. Most inkjet ink is produced using dye based ink which can flow easily through the tiny nozzles of the printhead, this type of ink is good for photos and colour shades but not so good for longevity or solid vibrant colour, think of it like a water colour painting. In recent years pigment ink technology has advanced considerably to enable use in inkjet printing. Previously ink pigments were too large and would block up the nozzles. This type of ink is good for solid colours and longevity, think of it like an oil painting.

Manufacturers like Epson, HP and Jet Tec are now increasingly using a fusion of dye based and pigmented inks to create superb quality photo printing with vibrant colours and longevity too.
Inkjet printers use anything between two and eight ink cartridges to do their job. Generally speaking the entry-level machines use two cartridges, good all round machines use four and specialist photo printers use six or more. The two cartridge system works fine though can be a bit wasteful on the colour ink, so go for a four-cartridge system where possible especially if you do colour printing. The six or more cartridge systems produce outstanding photos, but can be costly and a pain to keep changing cartridges (printer does not work if any one cartridge is empty).

Inkjet printers are the best solution for most people and are usually the most cost effective way to print – unless you are printing large volumes.

Portable Inkjet Printers
These printers are small, lightweight and ideal for people on the move. Although the printing of high quality photographs is usually beyond this type of printer, basic colour printing is of good quality and the quality of text print is mostly outstanding considering the size of these tiny portable A4 printers. These printers are not suitable for high volume printing.

Inkjet Printers
The Inkjet Printer is the most commonly used type of printer among home and small business users. With excellent all round printing capabilities, from black & white text print and good colour prints through to very hi-resolution, high quality photographs using Inkjet Photo Printers. Inkjet printers are available from cheap entry level to high-end business use machines and can print from photo size prints to massive A2 and bigger sizes, there are models for occasional use and others for high volume print jobs too. One of the many great things about Inkjet printers is that you can use a wide variety of media to print on, including standard paper, photo paper, card, t-shirt transfers, canvas, projector film etc, achieving different looks and textures for your prints and print for different purposes. Most Inkjet printers are USB connections and not suitable for networks, although models are also available for networks and with parallel connections.

Multi-Function Inkjet Printers
Multi-Function Inkjet Printers have been built to meet the needs of home offices and small businesses. These excellent value machines provide multiple solutions in one compact and easy to use machine i.e. printing, scanning, copying and some also have built in fax machines too. Not only are these machines great for saving space on your desk, but they are also very good for printing too using the same technology as standard inkjet printers. The only thing you should be aware of is that you can only use one function at a time and if anything goes wrong with an “All-in-one” machine, you may lose the all the functions at once!

Laser Printers

Laser printers work in a similar way to photocopiers, except they use a laser instead of a bright light to scan with. They work by creating an electrostatic image of the page onto a charged photoreceptor, which in turn attracts toner in the shape of an electrostatic charge. Toner is the material used to make the image (as ink is in an inkjet printer) and is a very fine powder, so laser printers use toner cartridges instead of ink cartridges.
Laser Printers have traditionally been the best printing solution for heavy office users as they produce a very high quality black text finish and offer relatively low running costs. However, laser printers have advanced a great deal recently and their prices have steadily dropped, as a result there are now compact laser printers, multi-function and colour laser printers all at very affordable prices. Laser printers make sense if you need to do a lot of high quality black or colour prints, not photos. The great thing about a colour laser printer is that they can print a very good quality colour image on standard copier paper, so you do not need to use expensive photo paper for large jobs. Do check the prices of the consumables before you buy the printer as these can be very expensive for colour laser printers.

Laser printers are the best solution for people who are printing in large volumes, that is, in 100′s of pages at a time or 1000′s of pages per month. Colour lasers also take quite a while to warm up, so are not ideal for printing single pages.

Solid Ink Printers

Solid ink printers use solid wax ink sticks in a “phase-change” process, they work by liquefying wax ink sticks into reservoirs and then squirting the ink onto a transfer drum from where it is cold-fused onto the paper in a single pass. Solid ink printers are marketed almost exclusively by Tektronix / Xerox and are aimed at larger businesses and high volume colour printing.
Solid ink printers used to be cheaper to purchase than similarly specified colour lasers and fairly economical to run owing to a low component usage, today it is not necessarily any cheaper than a colour laser printer. Output quality is good but generally not as good as the best colour lasers for text and graphics or the best inkjets for photographs. Print speeds are not as fast as most colour lasers.
Dye-Sublimation Printers

Dye-Sublimation printers use heat and solid colour dyes to produce lab-quality photographic images. Dye-Sub printers contain a roll of transparent film made up of page-sized panels of colour, with cyan, magenta, yellow, and black dye embedded in the film. Print head heating elements vaporize the inks, which adhere to a specially coated paper, as the ink cools it re-solidifies on the paper. Colour intensity is controlled by precise variations in temperature.

Dye-sublimation printers lay down color in continuous tones one color at a time instead of dots of ink like an inkjet, because the colour is absorbed into the paper rather than sitting on the surface, the output is more photo-realistic, more durable and less vulnerable to fading than other ink technologies.

The downside of Dye-Sub printers is that they are generally more expensive to buy and run, usually limited to photo sized prints only and can only print onto one type of specialised paper as well as being quite slow to print.

Dye-Sublimation printers are best for those who want to link up their digital camera to a purpose built printer and print out the finest quality photos at home without fuss.

Dot Matrix Printers

Dot matrix printers are relatively old fashioned technology today with poor quality print, slow and very noisy output. This type of printer is no longer used unless you wish to create invoices using the continuous paper with holes on both sides. The good thing is that they are very cheap to run!

Cost of Ownership

Many printers today are very cheap to buy, but people are sometimes shocked to discover the cost of replacing the consumables (ink or laser cartridges, imaging drums, fuser, oils, specialist papers etc). The cost of replacing the ink can sometimes cost more than the printer itself! This is one of the most commonly overlooked factors when printers are reviewed and yet one of the most important things to consider before handing over your hard earned cash. Tests run in 2003 by Which? magazine famously compared the cost of HP’s ink with vintage 1985 Dom Perignon.

A Sheffield City Council report aimed at helping schools decide on the best-value printers to buy, calculated total cost of ownership over the lifetime of a printer (not sure how long that is!). Adding up all the running costs, ink or toner, paper, maintenance and even electricity, SCC worked out that a colour inkjet costs approx 38p per page to run compared to a colour laser which costs approx 7p per page. Sheffield City Council advised its schools that if they printed more than three colour pages a day (assuming a 40-week academic year) they should buy a laser.

These figures cannot be taken hard and fast due to the many variables involved, but it is generally accepted that the cost per print of a laser printer is cheaper than that of an inkjet, which is in turn cheaper than that of a sub-dye printer. However, you would have to do a fair amount of colour printing to take advantage of the economy offered by a laser printer.

Summary

When buying a printer, firstly carefully consider its use, is it mostly general printing or for photographs, is it for occasional use or high volumes, will it be a stand alone device or connected to a network? Then using the guideline information above you will be able to decide on which type of printer is most suitable for you at the time.

For many years, dye-sublimation printers were specialist devices used in demanding graphic arts and photographic applications. The advent of digital photography led to the entry of this technology into the mainstream, forming the basis of many of the standalone, portable photo printers that surfaced in the second half of the 1990s.

The term “dye” in the name refers to the solid dyes that were used in the process instead of inks or toner. “Sublimation” is the scientific term for a process where solids (in this case, dyes) are converted into their gaseous form without going through an intervening liquid phase.

The printing process employed by true dye-sublimation printers differs from that of inkjets. Instead of spraying tiny jets of ink onto a page as inkjet printers do, dye-sublimation printers apply a dye from a plastic film.
A three-pass system (featuring solid dyes in tape form on either a ribbon or a roll) layers cyan, magenta, yellow, and black dyes on top of one another. The print head on a dye-sub printer uses tiny heaters to vapourise the dye, which permeates the glossy surface of the paper. A clear coat is added to protect the print against ultraviolet light. Although this method is capable of producing excellent results, it is far from economical. Even if a particular image does not need any one of the pigments, that ribbon segment is still consumed. This is the reason it is common for dye-sub printer compatible paper packs to contain a transfer film capable of producing the same number of prints. In addition, dye sublimation inks need a paper that allows the ink to remain on the surface of the paper.

Nowadays, a number of inkjet printers on the market are capable of deploying dye-sublimation techniques. The cartridges in such printers spray the ink, covering the page one strip at a time. The print head heats the inks to form a gas, controlled by a heating element that reaches temperatures of up to 500° C (higher than the average dye sublimation printer). A big difference in the results with dye-sublimation technique is that because the dyes are applied to the paper in gas form, they do not form distinct dots with a hard edge like inkjet printers. Instead, the edges are softer and blend into each other easily. Additionally, the infusion of the gaseous dye into the paper yields a more colour-fast picture.

Comparing Dye-Sublimation Printers and Inkjet Printers
Although it is difficult to point out every possible advantage and disadvantage when comparing inkjet and dye-sub printers, the following list mentions the major points that apply to most people printing photos at home.

Advantages of Inkjet Printers over Dye-Sub Printers:
·    Prints are very precise with sharp edges
·    Latest models offer incredible detail that exceeds most dye-sub printers
·    Variety of papers/surfaces available—including matte, luster, glossy.
·    Not locked in to one manufacturer’s paper
·    Some archival inkjets can produce prints that long-lasting
·    Most inkjets can print on many different surfaces that are designed to accept ink, including CDs, CD inserts, envelopes, etc.
·    Inkjets have a considerably larger colour gamut and usually produce more vivid photos than dye-subs
·    Easier to obtain large format inkjets that can print 11×14, 13×20 sizes, or larger
·    Inkjet printing is often cheaper than dye-sub printing

Inkjet Printer Disadvantages:
·    Often much slower than dye-sub printers
·    Most non-archival inkjets produce prints that fade a little (sometimes a lot) faster than dye-sub prints
·    Print heads sometimes clog and require cleaning, or even replacement

Advantages of Dye-Sub Printers over Inkjet Printers:
·    Very fast
·    Relatively maintenance-free
·    Smooth with no dot patterns visible, even under magnification
·    Produce excellent shadow detail in dark areas where some inkjets may be “blotchy”
·    Prints are usually more durable and more waterproof than inkjet prints
·    For many viewers, dye-sub printers produce photos that look and feel more like real photographs due to the smoothness of the prints and the absence of visible dot patterns
Dye-Sub Printer Disadvantages:
·    Consumer level models often smear high contrast edges (like a black square on a white background) to some degree, making charts, graphs, and line art look a little less “precise”
·    Dye-sub prints typically only last as long or slightly longer than a good non-archival inkjet printer and are generally not considered “archival”
·    Paper type selection is very limited and while dye-sub printers produce excellent glossy photos, most fall behind or do not even offer the option of matte prints
·    Dye-sub printers use an entire page and an entire page worth of ribbon even to print one small wallet size photo
·    Pages cannot be normally fed through the printer twice to fill more of the page as they can in inkjets
·    Dust can sometimes get inside and cause vertical scratches on prints
·    Dye sub printing and the cost of paper and toner (ribbon) is often higher than inkjet printing

The growing business of inkjet printers has brought about additional benefits to them. Manufacturers have built their business around the supplies rather than the printer itself. They have made the inkjet printers an inexpensive commodity sometimes selling them at lower cost or may be even less thereby making long term profits from inkjet printers.

An Inkjet printer uses a unique printer mechanism, which provides quality printing. They transfer tiny droplets of ink directly to the page. This is the reason why you will find most photo printers are inkjets. If you want to print photos at home, photo inkjet printer would probably be a perfect choice. For instance, if you want to print few photos, few e books or print any other project work an inkjet printer would help your cause. Inkjet printers are far less expensive than laser printers.

Tips to keep your inkjet cost low
•When you print inter-office, personal or draft documents use the “draft” and “grayscale” option. This can help you save a lot on black and color ink.
•Purchase generic cartridges made for you printer as they can be purchased at half the price.
•Purchase a cartridge refill kit as they are have an excellent quality and cost low.
•Always purchase your cartridge in bulk as this can help you bring down the total cost.
•Purchase remanufactured cartridges made for your printer
•Order you inkjet cartridge online to save time and money. Now days many online outlets do not carry the generic version and costs are normally lower.
