    The sensor it refers to is the density sensor located inside the machine via the right hand door. Open it and clean the large sensor in the middle. If this doesn't work then clean it with a vineager soution and a soft cloth.

Check the wiring between the PRCB and the Total Counter. There might be a short to ground close to the Total Counter. After the short is found and repaired, replace the PRCB (p/n A03UR75900).
If the wiring is not damaged, reposition it so that it is secured in the plastic hooks behind the counters. This will keep the wiring from being pinched when the cover is removed and reinstalled.
It is recommended that all machines be inspected at setup or the next service call to prevent future incidents.

    Possibly three problems.


    1. Your tech is cleaning the sensors but may not the cleaning pads so
    each time the machine is doing a color reg it is putting toner on the
    sensors.


    2. The transfer belt has not been assembled properly and it has more
    tension on one side than the other causeing the belt to buckle.


    3. The film seal in the cleaning unit is worn and it is spraying toner on to the reg sensor.


    Ultimate solution new belt assy and cleaner box and clean everything on the color reg assy with compressed air.

united%20sKonica Minolta Bizhub pro c6500 color copier - us%20alabama.gif= us%20alabama.gif CAUSE: ICP17 is OPEN on the Printer Control Board. The wiring between the printer control board and the hardware counters may be pinched. If the wire is shorted to ground, ICP17 on the printer control board will open, resulting in the error code. If the wire is broken internally without shorting, the machine will function but the counter will not increment.

SOLUTION: Check the wiring between the PRCB and the Total Counter. There might be a short to ground close to the Total Counter. After the short is found and repaired, replace the PRCB (p/n A03UR75900).
If the wiring is not damaged, reposition it so that it is secured in the plastic hooks behind the counters. This will keep the wiring from being pinched when the cover is removed and reinstalled.

I have a Konica Minolta C6500 and I have error code C4717 what can be done


Index sensor output does not
change by the execution of
APC. Index sensor cannot
detect the laser because the
polygon mirror does not rotate,
or because of the index sensor
out of position or defective index sensor

Basically the (Black print head/LASER UNIT/Write Unit) for Black drum is causing problems internally. Inside the unit the Index sensor output does not change by the execution of APC. Index sensor cannot detect the laser because the polygon mirror does not rotate, or because of the index sensor out of position or defective index sensor. Or one of the many control boards is causing issues with Black Laser Unit, such as:

Printer control board (PRCB)
Image processing board
(IPB)
I/F board (IFB)
Image memory control board
(IMCB)
Serious Cost for these boards, recommend a Konica Minolta Tech check this out. Sorry

Iam getting p21 error what can i do?


Sir/ Mam,

The P- codes in general are giving you a heads up that something is going to go soon. Most time you can live with them.This code deals with the registration of colors on the transfer belt. The belt put image on the paper and rides above the drums shine item when you open the right side door paper goes between it and the sponge looking roller.Registration is like cyan on top of magenta for purple if not you get to see both colors. Any way to get to the sensors that monitor registration requires removing the transfer belt then opening the sensor covers to expose the sensors and clean them NO LIQUIDS. Mite want a tech to come out and do this

Fix code 4522 on a Konica Minolta Biz hub pro c6500 (I think this is the color reg. sensor) just need to know where it is to clean it?


This sensor points at the transfer belt. It is located on the left side of the image unit cavity. Kind of hard to reach, and it's under a shutter that can be lifted with your finger. Pull the image assembly out of the machine. the reg sensor, and color sensor are on the left wall of the cavity.
