Adjustment Conditions
Line position adjustment timing depends on several SP mode settings. Among
them, the mode selection, SP5-993-1, takes precedence over the others. The table
below lists the conditions and the processes to be executed. Note that the
adjustments of the sub-scan line position, main scan line position, and
magnification are executed under the same conditions.
The numbers in the mode selection column indicate the setting of SP 5-993-1. For
details, refer to the description for SP 5-993-1 in the SP table.

NOTE:
1) “Recovery” includes turning on the main switch.
2) Fusing temperature is measured by the thermistor in the fusing unit.
Other temperature is measured by the sensors on the laser optics
housing unit.
