Ricoh Aficio SP C410DN toner error.

[Cause]
This may be caused by the Toner ID switch, that contacts the ID PWB on the Toner Bottle. The Toner ID switch has 4 wire contacts, if one of the contacts become crossed over this error may occur.

[Action]
Uncross and straighten the contacts.
If issue remains replace ID Chip Connector Harness [Part Number: G102 1120].

yellow toner is not loading
replace new yellow toner if it did't work replace the yellow toner pump

Look at the toner hopper closely there are little springs that some times get caught "down" they line up with the contacts on the toner. -Carl

sc364 is a black toner density error. Typically, replacing the black PCU will get rid of the error message.

Hi, SC361 is a Toner Density error in the Magenta PCU. Your best bet is to replace the Magenta PCU.

You could go in to the service menu, if you now how and do a TD Initialize on the magenta PCU - Service menu 3.801.004, but it may still not resolve the problem.

Go with the 1st, hope it helps.

There is no toner collection bottle for the 350, used toner is stored in the transfer belt unit. It must be pulled from the machine disassembled then empty used toner reassemble and put back in machine, a counter must also be reset, cant remember which sp code this is though.

Replace the toner holder/hopper part # B082 3209 -Carl

Go into the menu that says maintence )I think) and do the color registration.

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.

Unfortunately the newer ricoh equipment may include a chip like the HP toner. This allows the printer to track the usage so the printer can "intelligently" determine how much toner remains in the bottle. The chip overides all other factors on the remaining toner. Hence, if the chip "thinks" that the toner bottle has little or no toner left, it will give you a false toner low message. Presently, you can only replace the toner with a new bottle.
