Description:
SC29-07, SC29-08, SC29-09, SC29-10 error codes.
Solution:

PROBABLE CAUSES:
2. Setup adjustment performed incorrectly.
Recall the process adjustment standard data and perform the gamma auto adjustment after insuring that the drum cartridges and charge coronas are properly seated. To recall the process adjustment standard data, perform the following:
a. Power on the copier while pressing 3 and 6 on the control panel.
b. Select PROCESS ADJUSTMENT followed by RECALL STANDARD DATA.
c. Select YES and then perform the normal setup.

3. The transfer roller behind the transfer belt has dislodged from the power block assembly.
Check the corresponding transfer roller (p/n 65AA26120R) for the corresponding color code that might have dislodged from the power block assemblies (p/n 65AA-2810, p/n 65AA-2820). Also, check the continuity of the blocks.

4. Excessive yellow due to high yellow charge grid (shown on Adjustment List as Grid Y 1/1(V) setting = 1015), due to failed HV-1.
Replace HV-1 (p/n 65AA84010).

5. Bias contact on the rear of the developing unit is malformed resulting in insufficient contact with the bias spring located on inside of the machine on the rear side.
Reform the bias contact so that it contacts the spring on the inside of the machine.

6. Faulty Gamma Sensor.
Replace the Sensor Unit Assembly (Image Color Registration Unit) (p/n 65AA-2950).

7. Worn developer.
Replace developer.

8. The toner spew mylar located just below the magnet roller of the developing unit is misaligned resulting in the developer on the magnet roller not developing correctly on the sleeve resulting in PS11 (Gamma sensor) not reading the patch correctly.
Remove the developing unit, then loosen the 3 screws located on the toner spew mylar guide allowing the black plastic plate which the mylar is mounted on to move down. Retighten the 3 screws and reinstall the developing unit.
WARNING: Do not touch the screws for the doc blade because it is factory set.
