Reset printer ricoh sp 231

SOURCE: Ricoh CL3000 Laser Replace Waste toner

Couple of things to try: - If you just emptied the waste cartridge then you have to take the bottle back out and clean the insides as well. The sensor sees the toner on the walls and still thinks it?s full. FYI as typical the manufacturer recommends replacing the bottle with a brand new one. - If not that then you may have toner covering the optical sensor. Try blowing the area where the waste bottle attaches to the printer with canned air. Let us know if you have any other questions and please don?t forget to rate this post.

press .....clear modes 1-0-7 and hold clear/stop until the screen changes to service mode then unplug the machine and plug it back in and turn it back on Good luck

That is not a good idea. The oil is kept track of by counting pages, not by a sensor that measures the oil level. The oil runs out and the machine can't tell and now you have ruined the fuser. Which cost a lot more than the oil tank.
