- Kinds of Inks Used in Inkjets and Canon Pixus ip7500 Ink Cartridges
Posted by : Amanda Stein Friday, August 2, 2013
I have a Canon Pixus ip7500 printer which does all my digital prints and graphic design. I have always marveled at the high quality of printing that it shoots out at the push of a button. I decided that I had time on my hands to surf the web to find out more about the ink that goes into my inkjet printer and to see if my Canon Pixus ip7500 ink cartridges are as effective as I imagined.
In the 19th century, the concept of inkjet technology originated but was not developed until the 1950s. Canon was one of the first companies to develop inkjet printers starting in the late 1970s to print digital images from computers. Canon has also been one of the leading manufacturers of inkjet printers worldwide.
Thermal Inkjet Technology
Thermal technology is used by most inkjets. This is where heat is used to fire ink onto the paper. The ink is heated to create a bubble and the pressure forces it to burst and squirt onto the paper. The bubble disappears as the element cools down and ink is taken from the container to replace ink that was squirted.
Most thermal inkjets will have printheads containing nozzles needing tiny heating elements to eject the ink droplets from the nozzles. Nozzle density varies from 300 to 600 dpi and sometimes up to 1200 dpi is available. The ink used in this technology must be heat-resistant because the process is heat based and requires cooling adding to the overall printing time. Canon printers favor this technology.
Piezo-Electric Technology uses a Piezo crystal at the back of the ink container. When a dot is required the Piezo element receives a current which flexes and a drop of ink is forced from the nozzle. This method gives more control over the size of the ink droplet and therefore the density of the nozzle. The ink does not have to be heated and cooled so it saves printing time and allows better development of new types of printing inks.
There are various types of inks used in inkjet printers with some conflicting requirements for the colour to stay on the surface and not have the fluid quickly dissipate.
Most inkjet printers will use aqueous inks based on a mixture of water, glycol and dyes. They are cheap to produce but the ink is difficult to control on the surface requiring a coating to be applied to work correctly. Aqueous inks are normally used in printers with thermal inkjet heads which use water to function. The ink is not waterproof without the paper being laminated or coated after printing. Inks with a dye-base tend to fade rapidly after exposure to light. The pigment-based aqueous inks are more expensive but last longer and have ultraviolet resistance. Inks with the “archival quality” stamp are usually pigment-based.
Canon has placed a lot of emphasis on research into how best to create inks that work with all types of media. Traditionally, the dye-based inks which Canon uses are best for printing needs using bright and bold colours. Canon has improved the robustness of the dye-based ink with more colour variations and brighter pigment inks. Look for canon pixus ip7500 ink cartridges.
One of the problems with inkjet printing is when it is not used enough the nozzles get clogged. Canon has put in most models a replaceable print head in case that lasts the lifetime of the printer but if the nozzles get clogged it can be replaced. To prevent clogging it is important to print a few pages from the Canon Pixus ip7500 ink cartridges in black and colour to keep the ink flowing. The software utility programme that comes with the printer has a cleaning cycle that is good to run to clear up minor clogs and streaking of ink. If the cleaning cycle does not fix the issue don't give up as there are a number of ways to fix it:
- manually clean printer head: remove printer head and soak
- alternative cleaning method: purchase an ultrasonic cleaner
- preventive maintenance: cover the printer and buy a cleaning kit
I prefer to cover the printer and bought a cleaning kit online real cheap for my Canon Pixus ip7500.
Buying Inkjet Printer Cartridges
So what did I find when I went to buy my cartridges? Well, there are a number of ways to buy ink for my Canon pixus ip7500 ink cartridges as I found out.
- buy from Canon
- buy from an online source
- buy from a local computer shop
- buy third party ink cartridges
Most ink cartridges are expensive to replace as the printer companies try to recover profits from selling printers at lower prices. Some people say that it is better to look at online companies who sell cheaper versions of the cartridge but manufacturers will tell you that the quality of the ink from third parties is not always the best quality and therefore can damage the printer. Why settle for second best? So I decided to buy my replacement cartridges for the Canon Pixus ip7500 ink cartridges from a reputable dealer instead of taking a chance on damaging my printer.
