Good afternoon, I am a technician and I have the following problem, MP402 when I turn it on, a message appears on the screen, which says "install the toner cartridge".
I put in a new one and follow the message.
Change the PCDU, check the contacts of the chip ID.
Consult several technicians and I can't find the solution.
I need help
