Machine gave message to replace drum cartridge in R1 position. Replaced with new cartridge but I still receive the message. I have tried to reset several times but still receive the same message.
Go to Solution.
Do a Software/Network reset.
Try and clean the contacts inside the machine (upper part of the opening for the drum.)
Swap R1 with R3 and see if the issue follows it, if it does, the drum is defective, if it doesn't, the machine would likely need service
