Canon MP620 printer fixing

In jet printer is affordable, versatile and great at printing photos and graphics. But they have also set of problems. Troubleshooting common inkjet printer problems needs to be done too often. The most common problem with inkjet printers is not printing at all, poor print quality and the ink being very expensive. Usually print quality problems manifest themselves in the form of horizontal white lines running through each line of print. These white lines are caused by clogged nozzles that aren’t dispensing ink. Not getting any printout can be caused by even more clogged nozzles or printer being out of ink (often too little ink on one color means no prints at all).

The inkjet inks that use cartridge that has the print head and ink integrated to one piece are expensive spare parts. You can get cheaper prints with those printers that have a fixed print head, where you just add just ink. But still the liquid ink used in inkjet printers seems to be one of the most expensive liquids in the world.

But sometimes the print head gets clogged beyond what the built-in maintenance menu clean print head programs do. So I needed to do some more clean up, even with some risk that the print head gets damaged if I follow some cleaning instructions that were not exactly right.
