How can I tell may Xerox 5334 to feed toner?

Power the machine off. Press and hold the zero while you power the machine back on.
Then enter routent 9-05 and press start. that is the tone up procedure.

On this machine when their is no developer on the mag roll of the developer housing, this means it got all sent out to the waist developer canistor on the back.
The right way to put develor back on the mag roll is to buy another refill charge of developer to replenish the developer back into the housing.
A combination of things can cause no toner dispenser.
1. The toner motor was programed to dispense low amount of ink.
2. The developer housing is not firmly placed into the machine. The Blue socket is not mated correctly, causing the electrical pins not to contact. Make sure the door can close properly.
3. Any of the augars on the developer housing can be broken. They would have to be all taken off and physicaly checked. Especially the long tonor augar that dispenses the ink.
4. The front of the developer housing wall, where the tonor motor is bolted, may be cracked. This would cause the motor to turn, but the crack will cause the wall of the housing to move causing the gears not to turn to dispence the ink.
5. A bad tonor motor can cause no ink dispensement.
6. Check tonor motor to seeif there is any developer on the mag sensors on it.
7. A bad high voltage power supply can cause this type of problem.
8. A cracked copy cartrige recieving unit, housing can cause the copy cartrige not to sit properly in place.
9. A bad main ciruit board.
10. A toner cartridge with a broken spring inside the unit can cause no tonor to be pushed out of the tonor cartridge. When the big black wheel gear is spun, it should have a spring back tension on it. You should be able to feel the tension of the spring when it is turned. If it is free turning, the toner cartridge is not good. The toner is good, but the toner housing is not good.
Good luck.
