Canon Maxify printers use a "Printhead protection system". This means that if any situation occurs in which the printhead can be compromised, then the printer will lockdown. Hence, you won't be allowed to access or change the printer cartridges unless you convince the printer that the printhead won't get damaged.
These printers actually monitor the internal pressure of the ink system and purge the pump to ensure that the ink flow within the system is not compromised.
If the pressure is fluctuating a lot, then that means the ink is not flowing properly through the printhead. Hence, the small resistors in the printhead can overheat and may even damage the printhead. However, there is a setup protecting the printhead that is the weakest part of your printer machine.
Some of the common questions that people ask are how do I remove ink cartridges from my Maxify printer. Here, you will learn how to remove ink cartridges from your Canon Maxify printer.
Below are the steps that you need to perform to remove ink cartridges from your Canon Maxify printer.
