ENGINE SERVICE MODE
Specifies the number of sheets to be printed before a line position adjustment is
done during a print job. SP 5-993-4 must be enabled. When the temperature
difference meets the conditions specified in SP5-993-3, the machine starts counting
the number of prints in the job. The machine interrupts the print job and does the
line position adjustment if the number of prints exceeds the number specified in this
SP mode. If the counted number of prints does not exceed the number specified,
the machine resets the counter, then continues to monitor the temperature and does
the line position adjustment next time.
5993 024 Mscan Lgth Det
Performs the main scan length detection when the polygon motor has operated
consecutively for the time specified in this SP mode.
5993 025 Drm Gear Phase
Adjusts the phases of the black drum gear and the color drum gear.
5993 026 Initialization
Enables or disables the line position adjustment during initialization.
5993 027 Toner Refresh
Enables or disables the toner refreshing operation. Repetitive line position
adjustments can cause abnormal outputs such as white spots. To prevent this, toner
is consumed and supplied after line position adjustment.

SP3-906-001
SP3-906-002
SP3-906-003
SP3-906-004
SP3-906-005
This SP controls how often the automatic line position adjustment is done. For the
most accurate machine operation, set it to HIGH. If the user says that this
adjustment is done too often, which uses too much time, set it to MID or LOW (less
accurate operation but less time used).
5994 [Unit Set] Maintenance Unit Detection ON/OFF
5994 001 Dev/PCU
Enables or disables PCU and development unit detection.
NOTE: If this mode is disabled, new unit detection also does not function. Use this
mode as a temporary measure, only when the micro-switches are defective.
