I've had this a few times as well. I believe the thermister comes apart and gives poor temperature comtrol so damaging the belt.
Check the thermister. It should not be separated at the contact end.

As Zeldaman and Teebee1234 said, it is a unique code relating to that copier.
As far as I know all Ricoh digital colour copiers have produced it. The pattern is only visible using a magnifying glass.

Unplug the HDD and see if the code shows.

Rubbish. Almost impossible to locate the part you want. What the hell were they thinking?

Hi Rick.
SC471 is transfer unit lift error.
Remove the ITB unit from the machine and check the right side of the unit is free to lift and fall. Also check the lift sensor inside the machine, it can...

I've had this on an MPC3300 (Athena C2). Display was blank and printer light red indicating an error. Found showing SC202 using WIM.
The polygon motor was faulty and had taken out the BICU board. I...

Have you tried Web Image Monitor to see what SC code is being displayed?

Glad you got it sorted. I'll check that setting out next time I see one.

The brightness and contast for copying can be adjusted in the user menu. This can easily be adjusted by the customer playing with settings.
Press menu, scroll down to main-menu 3-copy, scroll down...

Been working on many of these machines since they were first launched and I've always used the J-C1 drum unit (B1909510) for both machines without any problems. Just remove the little blanking plate...

If the colour registration is out by more than 1.4mm, then SP 5-993-2 will fail. Carry out rough line adjustment first, SP 5-993-39, then fine adjustment SP 5-993-2.

The transfer belt lift sensor can get quite dirty with toner. There is a tab on the rear of the transfer unit that goes through the sensor.

SC481 is often caused by a damaged transfer belt. With the PCU out of the machine, rotate the belt transfer belt completey and check for any damage on the edges.

+1 on lift motor failure, but not sure about the part number. I've been fitting AX050277.

The ITB cleaning unit is slow to lift off the belt causing the start of the black image to be smeared. You could try replacing the lift clutch, but normally this does not work and replacing the...

Check to see if the registration sensor harness is damaged. It is easy to get it trapped between the reg sensor guide plate and the reg roller rear bushing. The wire can break trough the insulation...

I think SC792 is displayed when there is a bridge unit and no finisher. The machine is expecting to see a finisher connected to the bridge unit. Remove the bridge unit and the code should go.

The procedure to load the dev must be carried out correctly or it will not work . The manual seems to be incorrect on how to do this.
Vigorously shake the dev bottle for about 5 mins and the attach...

I've had this a few times before. I agree with teebee1234 that replacing the drive pack (transport bracket) will cure this. I've tried stripping the unit and replacing the ITB cleaning unit lift...

+1 on laser problem

The fuser exit sensor is held in the side door above the transfer unit. This sensor looks at a square recess in the fuser unit cover. The recess can get quite dusty and cause the sensor to have a...

Check that the transfer cleaning blade is not sticking to the belt, this is usually accompaniend by a juddering noise.
Cheat the front door, run the machine and release the blade pressure with the...

To reduce the toner supply use SP 2-209-1. Default is 30mg/s, try incresing it to 70mg/s. Believe it or not, the higher the number the less toner is added!
Also check if the drum is worn (life is...

+1 on that.
Check for diagonal bands in solid areas and if dev unit feels very light, definately faulty clutch

Hi Bostjanma,
The 90 and 110 cpm machines use AE011108 and the 135cpm machine uses AE011110.
