Ricoh SP4100 printer problems

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.

My machine had the same problem. A service tech looked at my machine and pulled out the OPC Belt Drum Unit. The drum unit had a few issues: 1) jagged rips in it, something caused by running papers through that had staples or paperclips in them. So when the drum turns, it scrapes other parts and the machine sounds like its going to drop all its nuts and bolts--at least mine did!)! and 2) the spindles from the OPC unit has come loosened and fell off. The spindles and plastic cogs were found way at the bottom of the OPC Drum slot. This too was thought to have added to the rips in the drum.

I replaced the drum ($399 was the cheapest I could find) and the problem went away.

An expensive repair but for me it worked...

It sounds like the part the toner bottle slides under to lock in place is broken. you could try and fold some paper and tape it to the toner to hold it down.

In the front (inside body) see the sensing feeler ( a piece conected to a microswitch) is free to move.
Sometimes when pull the paper with some force, the sensor become forced in their base.

Verifie if the sensor is moviming free..

This is probably one of two things, first it could be is that the stopper out of the old bottle has got stuck inside the Toner hopper and preventing the hopper from getting toner from the new bottle.

This would be caused by the second problem that is the hopper is more than likely clogged up and the jaws that grab the toner bottle cap cannot open, you can either clean the hopper out, it can be dismantled by removing the silver pin on the green handle, but do be care full as when this pin is removed you will fire the internals out accross the room, so have your hand in front to cach them, then just clean it out reassemble and you should be fine.

Just remember always try the simple fix with copiers, so many engineers look way to far into problems whenit's staring them in the face, i am a Technical Specialist with Ricoh Masters and find a lot of basic faults are overlooked
