Have you added toner resently? If so you will have to emptiy out the waste toner. The bottle is filled with toner and has set a flag in to a sensor.. I believe the waste toner bottle is in the front of the copier on the right side. It has been awhile scine I've worked on this model.... It may be behind a door on the right side of the copier toward the back of the copier... Be carefull when you empty out the bottle...... Use a plastic bag with No holes in it..... The toner will go every where if you are not carefull... Good Luck

How can i fix my aficio 2027 w/ loading toner error

Not loading toner is usually due to worn out dev gears in the PCU. Call your nearest Ricoh agent for a service call. A technician must come and fit new dev gears. Or the toner hopper is dirty and needs cleaning.

Many copiers will do this if you have run out of toner.Copiers will turn over trying to add toner from the cartridge to the developer unit.

I have a Sharp AR-507. Error F2-00. How to fix?

It could also be the sponge roller in the toner hopper. The old ones started to deteriorate after a while so sharp modified them.

Light copies

NEVER, EVER touch the "green roller" (drum). Are copies worse than before you cleaned it. I wouldn't be surprised

Have you cleaned the optic's? what roller was replaced? Was it the drum unit? If not you may need to replace the drum unit.

Toner error message on copy machine

Is "CH" steady or flashing? If it's steady, the door is not shut properly.
If it's flashing, the machine doesn't detect the presence of the toner cartridge (defective toner cartridge). Try another toner cartridge (an empty cartridge will do).

To get the blue handle to stay locked sometimes takes fiddling with it when the cartridge is in.
