A canon printer can malfunction because of underuse, overuse or other forms of misuse. Although these printers exist in different models, the same basic procedure is followed when fixing most of the problems. However, repair techniques may vary with models when solving complex issues. Before you hire a technician to do canon repairs, find out the model of your facility in order to make the right decision.

Modern printers are mainly divided into two categories. One of them comprises office devices that are designed for professional use. The other category comprises consumer devices made specifically for personal use. Every expert who performs canon repairs should start the process by performing diagnostic troubleshooting especially if she or he intends to correct a firmware error or repair the hardware.

Basic procedure to follow during the repair process

Reading software error message

Most hardware problems produce error messages. An expert can only notice such information if the operating software and printer drivers are up-to-date. In some models, a specialist can see error messages without the help of attached computer, if he or she goes through LCD menus checking for status alert and error codes. Serious errors tend to generate fault message or troubleshooting code. Technicians who do canon repairs are normally advised to go through the device readout before they start solving any type of a problem.

Printer inspection

Some errors like snapped covers and broken displays are obvious and can be identified with ease. On the other hand, the complex ones require intensive inspection before they can be noticed. Each specialist in canon repairs Sydney has now starts off by inspecting the outer part of the device he or she is working on. This helps him or her notice dents, gouges or cracks that may cause internal damages.

It is true that most of operational problems do not occur as a result of superficial defects. However, printers with roller mountings and casings, which have been crushed, cannot produce documents that are properly aligned.

Access panels of commercial printers are opened to see whether the print heads that move over metal rails and toothed drive belts are in good condition. The teeth must be regular and even. The head cannot move smoothly if the belts are chewed-up.

Basic repairs

When a technician doing canon repairs identifies either an error code or a broken part, she or he should consider going through the printer maintenance or service manual. Problematic parts that need to be replaced are removed by removing screws and loosening tabs used to attach them into the printer’s body. Disassembling of cases is done with great care to ensure thin sheets of metal are not destroyed.


All the removed broken components are replaced with brand new parts. Many technicians, who perform Canon printer repairs, buy a complete dead printer in order to get the right scrap parts from it. When it comes to print heads, technicians really consider the printer model and specific part number of the parts they are dealing with for compatibility reasons. New parts are installed considering the way old ones were uninstalled. The right priorities are maintained when solving problems associated with electrical connections.
