Open right door.
Density sensors (5) are located above the transfer belt behind the black plastic cover. Use a damp rag to clean. If you are trying to clear SC400 code, you will also need to pull out the transfer belt assy enough to take off the silver plate that is on that end of the assembly and clean it too. Toner builds up on the silver plate.

Hi I have a Konica Minolta C-550 I appear P. -21 code After I changed the UNIT appeared to me Code P. -5 What should I do


I am going to assume you replaced the Transfer belt and transfer roller. Since you did not state that in your input. You did replace both at the same time. Cleared the counter for the transfer roller in the service mode?. Anyway the code P-5 and P-21 have to do with the registration sensor located below the transfer belt. On the right side of the machine. Where the edge of the belt is and exposed below the belt and behind the large plastic part below the belt there are two sensors one to the front the other to the rear of the belt, again below the belt assembly. It will require you the expose the sensors clean them. Worse case have them replaced, or the Main board!!!!. Recommend you have a Konica Minolta tech come out and do this procedure. P-5 is the front sensor failure

How to solve error SC471 on my Ricoh alficio cl7000


This is a transferbelt home position error.

Book says:
1. Turn the main switch off and on.
2. Reset the transfer belt unit.
3. Clean or replace the transfer belt
sensor.
4. Replace the transfer belt contact

remove the cleaning unit 1 screw and a thmb lever slide the unit out (its on rails) wipevacum and/or blow clean the unit and re assemble
also clean the connector that it plugs to in the back of the machine
(q-tip)
if it still appears belt or unit will need to be replaced
