Ricoh mp 2851 SC 401

[BEBEDELFUTURO]

After performing preventive maintenance the sc 401 appeared after 100 sheets

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.

[BEBEDELFUTURO]

The module is new.
Another solution please

Have you replaced the paper transfer roller?

[COPIERMAN]

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.
