[Error Code] bizhub C552 shows up to 3 times a day error C8104 (glass movement trouble)

[Laserbeam]

Hello at all,

a bizhub C552 (in a copy-shop) shows up to 3 times a day (since several months) error C8104 (glass movement trouble).
I checked the ease of the glassmovement. Everything goes smoothly.
A few days ago I renewed the ADF-wire, unfortunatelly without success, the error is still displayed.

The next step would be the exchange of the glass movement unit and PS203

Or has anyone of you a different solution?

Hope you figure this one out.
I had a a C452 with the same issue i replaced all the relevant components including the assy the sensor the motor and the small control board where the motor plugs in.
strange thing is it would not happen if was close to it.
The contract ended and the rest of the techs set on it like a flock of vultures.
The last thing i would have checked is if it needed the old bear hug(warped scanner assy).

PROBABLE CAUSES:
bizhub C451/C550/C650
1. Failed Glass Movement Unit.
Replace the failed Glass Movement Unit (p/n A00J R706 00).

2. The covers are not properly aligned around the glass.
Remove and reseat the covers surrounding the glass (p/n A00J 2882 03 and p/n A00J 2892 00).

3. The dustproof seal in the ADF slit glass movement unit can become damaged or worn. Friction can cause the edge of the seal to peel up, interfering with proper glass movement during the cleaning process.
A seal is available to compensate for a worn or damaged dustproof seal. The seal is installed over the edge of the original one, providing a smooth and more durable surface that will not catch as the slit glass moves underneath the sheet assembly.
Replace the Seal (p/n A00J 2911 00).

4. The covers are not properly aligned around the glass.
Remove and reseat the covers surrounding the glass (p/n A02E 2882 00 and p/n A02E 2892 00)

5. Failed Original Glass Position Control Board (PWB-ID).
Replace the failed Original Glass Position CB (p/n 9J07 0104 02).

6. Incorrect setting.
Perform the following:
a. Enter Service Mode.
b. Select System 2.
c. Select Split Line Detect.
d. Setting.
e. Set it to Not Set.

7. Failed Glass Movement Unit.
Replace the failed glass movement unit (p/n A0P0 R709 00).

8. Failed Original Glass Position Control Board (PWB-ID).
Replace the failed Original Glass Position CB (p/n A0P0 H01B 00).

9. The covers are not properly aligned around the glass.
Remove and reseat the covers surrounding the glass (p/n A00J 2882 03 and p/n A0P0 2892 00).

10. Slit glass holder is applying to much pressure to the glass not allowing the cleaner plate to go all the way back into home position.
Carefully form the slit glass holding brackets to alleviate pressure between the slit glass and the cleaning plate.

11. The shaft of stepping motor (M202) is locked and does not rotate. A glue-like substance may be hardened around the motor shaft and the bearing.
Rotating this shaft or sliding the Original glass by hand releases this locked condition and afterwards the motor should work without any problem. If not, replace M202(p/n A00J M12B 01).

12. Rear cover may have pinched one of the wires within the harness.
Remove the rear cover of the DF-610/Df-611 and inspect the wiring.

If it could be disabled... sounds like the way to go.
The new machines are better in that respect.

Problem solved!!!

On the inside of the tooth-belt (M202) was a very small piece of cardboard. This sometimes prevented the correct drive of the tooth-belt.
