Ricoh MPc Range – Cheating Out Of Toner

 

 

Right, you have a machine which insists that it is out of toner when it isn’t. I’ve had this twice of late and here’s how I got around it.

  1. Enter SP Mode
  2. Go to SP 3045 – Toner End Detection Set
  3. Turn this off (or 1)
  4. Turn the machine off and back on again. Check the toner levels in System Status – they should now all show as being full.
  5. Go back into SP3045 and turn Toner End Detection back on again.
  6. Turn the machine off and back on again. Check the toner levels in System Status again – they should all have reverted to their previous levels with the exception of the colour which was initially showing as being empty.
This worked for me twice, despite Ricoh’s product specialist seeming very bemused.

This problem seems to have been cropping up more and more of late, mostly leading to some of our engineers doing full fuser services or simply making up excuses for what is causing the fault.

 

The technical bulletin attached explains what to do, namely replacing the two sensors which register that the fuser unit is turning, plus the encoders which trigger said sensors. However, the most important procedure is to update the firmware, something which our lot seem to be loath to do.

 

Additionally, and this was in a much earlier bulletin, these sensors were modified to try to prevent the user from knocking them out of their housing brackets should the fuser be slammed into position.
