Resetting Printer Memory on Canon Pixma MG2550s After Cartridge Refill

Hello.
I got this printer for free from Orange, traditionally I fill cartridges with ink from a "cylinder" and I have a problem with resetting the printer memory, otherwise the cartridge counter or the like (in any case there is a low level alert and the diode is on, for now from black) . In the previous HP, I sealed the contacts, here there may be a key combination, but I can not find information with details. Please help. greetings

Hello.
Did you solve the carcass problem in the abovementioned printer ???
greetings

When it ends completely (the LED will blink) the red button is held for 8 seconds and you can continue printing. It shows that it is empty but the printer allows printing.

It seems to me that the head has dried up because after filling with ink and cleaning the nozzles, the test print comes out with broken lines. Thorough cleaning does not help either. It is possible that I also poured the wrong ink.

in the software there is an option to clean and clean exactly somehow named. If a test or "normal" printout is not good, it is enough for me to clean the option once or if the cartridge is more annoying, then clean it thoroughly and choose the color with which you have a problem and wait about 24 hours and the prints in the worst quality are satisfactory -> I'm talking about the cartridge with black ink. I think I have an xxl replacement, not the original, and if she did not want to print after loading, as I sometimes have, then you need to insert a cartridge into the device or cut it yourself from hard rubber (car suspension bumper -> damaged) and drill a hole for the syringe from the bottom. Apply the rubber with the syringe to the nozzles of the head and forcefully draw the ink into the syringe. These are the 2 ways to get a cartridge open after loading ink, and they help.
