replace the black pcu(drum unit). the life of the pcu(s) are 15k each(blk & col) . the machine will work but copy quality will reduce and the error will be there. replacing the cartridge has nothing to do with this error.
A 440-1 is a black drum motor lock. The waste toner in the black pcu is backed up, more then likley. It is not easy to fix. You could replace the black pcu but it will happen again. The usual problem is oil in the main waste toner system. It clumps up the toner and clogs the part where all the waste toner comes together for entry into the waste toner bottle.
Hi there the following is the description from the service manual hope this helps you Thanks J
441 PCU (CMY) motor error The drive motor of the CMY PCU is not locked. • Defective gear • Voltage between pins 2 and 14 (CN12 on engine control board) abnormal (not +24V), or pin 12 (CN12 on engine control board) unable to send motor clock • Defective CMY PCU drive motor 1. Replace the CMY PCU. 2. Replace the engine control board. 3. Replace the main drive unit assembly.
I would try replacing the CMY PCU (Drums (Photo Conductor Units) first before any of the others.
One of our Ricoh CL3500N printers- less than a year old- gave us a "color regist error" after changing the transfer belt.
Ran the "adjust color regist" without results. It would just finish and pop back up with the same error.
Color test page printed no color, just BW
I reseated everything, and even replaced the PCU without positive results.
A couple hours later I went back, took everything out (be sure to keep the pcus out of the light!), and vaccuumed the heck outta that printer.
For whatever reason- maybe there was a chunk of toner hanging out, maybe I knocked something loose or back in place, whatever- but when I put all the parts in and turned it on, the error was gone and color printed great!
I'm not sure how to obtain one, but "Black PCU" stands for Black Photoconductor Unit, and according to a manual for a different Ricoh printer model, it should be fairly simple to replace if you can find one.
