Customer installed a black non oem cartridge and a week later gets add black toner message. Prints are very light. Cartridge is full by weight. Sent a another OEM black cartridge and installed. Still same problem. Reset machine, turned off and unplugged, remove black cartridge. Closed door with black cartridge out. Plugged in and turned on using side switch. Machine came to ready. No black toner detected. Turned off, unplugged, re install black cartridge and turn on again. Works for a few minutes then calls for new black toner. Prints are very light. Ordered a new DV unit, installed according to instruction, perform firmware upgrade, half tone sim. Worked for ten minutes then add toner again.
Anyone want to take a wild guess about the fix?
