Question about Lexmark T642 Laser Printer
We have a Lexmark T642 all worked fine but we put in compatible one 64035HA toner and we get 929 error stating "Service Sensor is On".
At some point, before we turned off the printer we where able to get one page at a time.
Thank you so much,
Not a chip error but a mixing rod/pac man gear problem. either way the cartridge is bad....shaking could help as hard toner can cause the mixing rod to bind.

Chip on toner is bad, try puting in old one to reset and switch it with new one, sometimes turning off and on several times helps.
