By mistkae I bought 3E MYC installed and have been using them for about a month with no problems. Today the "WRONG CARTRIDGE" message started to flash and sheets feed through but nothing prints. I replaced the 3E MYC with 6MYC (all are OEMs), but it still says "WRONG CARTRIDGE" and does not show full tanks on the display. I have tried all the maintenance options...no luck. Is this a print head thing too?
I use new BCI6 cartridges and have had no problems for over a year. I just replaced the "M" cartridge and the message started flashing, along with the "alarm" light. I removed all of the cartridges and replaced them, making sure they were all seated properly. No luck.

I have to ask this question of you, just to make sure this is not an issue.Are you using a factory new ink or toner cartridge? Please consider the following: If you are using a refilled (theabsolute worst possible choice) or third party cartridges (2nd. Worst possible choice) that may well be your problem.Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges. They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors. If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges Don
