A 929 Service Toner Sensor error indicates a problem with the toner sensor, the front harness cable, or the developer drive. It could also mean that the toner cartridge is defective.

* Check the main exhaust fan first. All models of these printers have a main exhaust fan. The main exhaust fan is located on the top of the printer, on the rear left side.

1. Make sure nothing has fallen down into the main exhaust fan that could be blocking it. There are vent slots/holes in the top cover of the fan, on the left-hand side. Look through these vents/holes.
2. If there is an item stuck there, see if you can remove it. If not, you will probably need to have a technician remove the top cover unit and extract the jammed item from the fan.
3. If nothing appears to be blocking the exhaust fan, power off the printer and let it sit powered off for at least a minute. Continue Reading »
