Software Program Change to Prevent EEP-ROM Damage
ertain machine functions can cause a communication conflict between the Main EP-ROM and the EEP-ROM
(P/N 33227030) on the Main PCB. The communication conflict can damage the EEP-ROM. To prevent this
problem, the Main IC ROM software has been updated. If the problem occurs, both the Main IC ROM and EEP-
ROM must be replaced at the same time.
Secondly, a high temperature offset problem may occur in the field after the main switch is turned on. Simulation
48 (Setting the fixing unit stabilization time) has been added to prevent this problem from occurring.
* Mode 1 (Exp 1 lights): Stabilization time in normal temperature conditions
Default is 29 (seconds).
* Mode 2 (Exp 2 lights): Stabilization time in low temperature conditions
Default is 100 (seconds).
Increasing the stabilization time can reduce the degree of the fixing offset.
Note: The setting range is between 18 and 120 for both modes above. The mode can be selected with the
exposure key. One increment is equal to one second.

Measure to Prevent Damage to the Drum (Service Parts)
n some cases, if the Drum Unit is twisted counterclockwise when being installed into the machine, it may come
in contact with the Main Charger Grid resulting in damage to the Drum. To prevent the chance that this can
occur, the shape of the Front Main Charger Housing will be changed so even if the Grid comes in contact with
the Housing, the Housing will have room to shift so the Drum will not be affected. Instructions outlining the
precaution will be included with the Drum Unit (supply item).
