Question about Ricoh Aficio AP3800C Laser Printer

2 Answers


I have 3 AP3800C printers - all of them say add toner black, even when i replace with a brand new original black cartridge.

I have tried blowing the pipes through and executed forced toner but have had no success.

Hope you can help

If the toner is an original you should not have a problem unless the Developer unit is faulty. The developer unit mixes the toner with the dev. If the dev unit TD (Toner Density) sensor is not working then it will not add toner. Try the following.

  • Remove black drum unit
  • Remove Black Developer unit
  • Tap the develop unit and shake side to side 5-6 times
  • Reinstall both units close covers and open toner cover
  • wait 15 seconds then close the cover
Hopefully then you will add toner if not the likely thing is that the developer unit will need replacing.

Hope this helps
Thanks J

My cartridge is full of toner but the printer says it needs to be replaced, how do i reset the cartridge?

You can't. The toner levels are calculated and approximated. Make sure you use genuine Kyocera toner and replace it.

HP 2840, black ink drum q3964a

Hello, these printers tend to be finicky.

In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.

Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.

Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.

Open the front door and close it and check if the display reads loading toner. Try this for 3 times.
If Add toner indicator is still there, check that you had removed the black cap of the toner, before you replaced the toner bottle.
Remove the bottle from the holder and check inside the neck of the holder if there is something blocking the toner supply. (sometimes the inner plastic cap of the previous toner is stucked in the neck).
Check and clean the toner bottle holder unit.
Another problem can be worn gears in the lower development unit and within the dev. bias roller.
Good luck and please rate me, thanks.

Epson Aculaser C1100N - Black Toner problem

IF the problem persists with an original cartridge then the factory settings should be restored refer the manual or go through the settings in the control panel . minimise the tone of printing . If toner is getting accumulated in the printer then it might be due to refilled toner not the original cartridge . use the original cartridges
