The machine should automatically recognize the new PCU. Blank copies would lead me to think you have further problems, charge corona? transfer issues? If you try to make a copy and open the front door real fast when the paper should be at the transfer unit, is there an toner image showing on the drum? If yes, then you have charge but not getting transfer. This is a hard problem to troubleshoot without seeing machine. Anyway good luck, please rate this. Thanks ..... Wait... just had a thought. On the shaft, on the inside of the rear frame, that drives the drum there is a coupling that is spring loaded. Sometimes the shaft gets gunked up and coupling does not pop out not connecting to the PCU, which could cause blank copies and will still say replace pcu. You could add a couple of drops of oil to that shaft to loosen it up if that's the case.
Hi, SC 392 Possible causes -
· Someone forgot to remove the toner seal of the PCU
· ID sensor defective
· TD sensor abnormal
· Drum does not turn
· Development roller does not turn
· Poor connection of the PCU Regards,
Ghosting can be caused by several components: 2nd BTR transfer roller, Photoconductor Unit (PCU) or the Fuser unit. The most likely is the PCU contacts being dirty, caused by toner getting between them. Open the front of the printer (cover B) and lift out the photoconductor. Clean all of the metal contacts down the sides of the PCU with a cloth and wipe out any loose toner from inside the printer and give the contacts inside the printer on the R/H side a good clean. Replace the PCU and close the front cover.
Hopefully all will now be well, if not open cover A and clean the transfer roller on the inside of the cover. If problem persists you will need to get a Tech out to look further as without seeing the printer it is pretty hard to diagnose.
Please open the front door and turn the blue lever in the middle,
remove the Transfer and Separation unit and check if the bushings of the transfer roller are damaged.
If OK, please give some oil on the shaft/bushings of the transfer roller. This unit may be replaced as a whole unit.
If SC401 re-occurs, please check the Photoconductor unit (drum).
Most of the time when I find this happening on a printer, not just Ricoh's it turns out to be the PCU (photo conductor unit). The color PCU is one unit and the black is a seperate unit. Hope this helps.
