photoconductor unit is a drun unit which does the actual copying of image on the paper. its life is 60,000 copies. its will need a replacement because after a while you will notice there are black marks appearing on your copies or your copies are not good or black shades. photoconductour unit is just beside toner supply unit. you can pull out the whole unit.
Do you mean the photoconductor unit? To replace the photoconductor (PCU), open the front cover and the right side covers (the duplex door and the main side door). The PCU sits to the right of the toner bottle -- it is a black unit that has the blue cylindrical drum facing the right side of the copier.
On the upper left side of this unit is a ridged tab. Push this tab in and slide the PCU all the way out of the machine. Open the box with the new PCU and remove all of the tape and paper, then slide the new PCU in where the old one came out of. When you shut all of the covers, the copier will recognize the new PCU.
The Photoconductor Unit or PCU is easy to replace. The box will come with instructions but it is basically a slide in unit. They will vary in price depending on where you go. You might find one on Ebay cheaper but they generally run around $225. Keep in mind this is a drum/developer unit combination so you are replacing pretty much everything that controls copy quality.
Ricoh part number is 411018 or a type 1027 photoconductor if that helps your search.
