ADJUSTMENT
1. Position-B Adjustment (Print drum removal position)
CHECK and ADJUSTMENT
) Using Test Mode No. 0892, stop the Print drum at Position-B.
2) Confirm that the Print drum can be pulled out from the machine and inserted back in the machine
smoothly.
3) If the Print drum cannot be pulled out smoothly or inserted back smoothly, make the Position-B
adjustment using Test Mode No. 0942.
4) After the adjustment is completed, repeat the adjustment procedure until the Position-B
adjustment is correctly make.
Precaution in Adjustment
) Basically the machine is designed to have the Position-B adjusted correctly with the parameter
setting at [0] on Test Mode No.0942 (Drum angle = 270 degrees), but this may vary slightly
between the machines and this adjustment may become necessary.
2) The Position-B is calculated by the Main motor FG sensor pulse count from Postion-A sensor.
If the position of the Print drum is way off from the normal Position-B, the Postion-A sensor and
Main motor FG sensor should be checked.
