Canon MG2950: How to Enter Service Mode, Reset Waste Ink Error & Resolve Kod 5B00 Issue

Hello
I am looking for a way to reset the waste ink error on the canon MG2950.
I did not find in the depths of the Internet a description of how to enter the service mode and information about which srevice tool to reset the error.

It gives the procedure to Reset Pampers:
Download ServiceTool V3400
The printer needs to be put into service mode.
1. With the printer turned off, hold STOP, turn on the printer, release STOP while holding the POWER button and now, while holding the power button, press STOP 5 times, then release the POWER button.
You are entering ServiceTool V3400
2. You press EEPROM, a window with values will pop up (i.e. it connects to the printer) as there is error 006, i.e. the printer has not been entered into service mode, something wrong done in 1 point
You close the window with the values.
3. Press SET at - Counter Value(%) (0)
You close everything and turn off the printer after turning it on it should work.
