I had one that the drum shutter was not opening properly. Make sure the front cover on the pcu is not binding and causing the cover to not open.

Thanks for your reply I commented that the module that I am occupying is a 1027. if what you are referring to is a transfer unit does not open the protective cover of the module.

The last time I check the sheet I get it in the middle of transfer and the module and mark the sc 401

Check transfer roller is contacting drum correctly, replace roller.

Thanks for your reply I commented that after completing the preventive maintenance the frame equipment sc 411 at that time change transfer roller and corrected after 1 day frame sc 411 disassemble transfer the clean and sack 80 sheet and frame the same sc and the Sheet remains in pcu and transfer roller and does not rise to melt.

I have had a sizable percentage of these have teeth get chipped off on the drum cover flap. Remove the cover flap until you can get back with a new one.

Re: Ricoh mp 2851 SC 401

The module is new.
Another solution please

Have you replaced the paper transfer roller?

Re: Ricoh mp 2851 SC 401

have you replace transfer roller bushings. could be you have toner and developer dust around the transfer roller area causing to short to ground. make sure area is clean along with contacts and check inside copier where contacts meet. I found cleaning the rt side door area most of the time resolve it. You can also try unplugging the transfer connector from HV board just in case it is lose.

If by "module" you mean the drum unit, I have seen a new machine with less than 500 copies with a chipped gear on the drum shutter.

I am with Slimslob on these flaps being flimsy to say the least.

The "good book" says that the cause of the code is either transfer roller or pcu flap that does not open completely.

Re: Ricoh mp 2851 SC 401

Customers try to lift that flap during jam removal and they will make it jump time or even break teeth. They will deny it but I put a label on the outside of the flap that said "do not lift this cover" When it is open and in operating position, the label is folded up and out of the way. The only time it is seen is when the side cover is open. After putting that label on, mysteriously, they quit having problems with the shutter getting out of place.

Thanks for your response change the transfer roller but the bushings that hold it are stuck toner, clean transfer and disconnect the sensor ... I think I need to diagnose that ... I tell you if it was corrected.
