Please rate my help++++Thanks for using FIXYA

Your toner cartridge is probably getting low. Toner is actually a powder, and it can get settled during shipments, bringing it home, etc etc. Take out the black toner and give it a gentle side-to-side shake a few times and pop it back in.
That should help.

Look on page 11.

Ricoh recommends heavier paper be run from the
bypass tray 16lb to 53 lbs are the recommended weights

Never clean or touch the Transfer Roller (spongey rooler) unless your using a dry cloth or vaccum as last measure.

Usually the transfer roller sits on a drum/pcu specific to that color. If you can tell which color is sitting on to of the roller replace that drum/pcu.

The voids and blotches can be a bad black pcu, the voids san also be toner on the glass slat obove the pcu,s there are 4 slats one for each color, on the pcu itself on the upper side is a narrow long opening, the glass slat is above this opening when the pcu is in the printer. It will take a flashlight to see any toner on the glass.

Hello sir; Believe or not , you need to replace imaging unit.

It may be the fuser. Take it out and inspect the roller on it:

1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
3. Open the front cover by pressing the release buttons as shown.
4. Pull the front cover down towards you.
5. Disconnect the green plug - squeeze the sides of the plug and pull.
6. Push the left and right levers outward to unlock the unit.
7. Pull the unit towards you as shown and lift it clear of the device.
8. Check the roller for wear marks, If so replace it.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

I changed out our black photoconductor unit #165 and it solved the problem. Even though the error message did not say that the photoconductor needed changed out, it had been eight months since the last replacement. I hope this helps!
