SP2 Mode Number Function and [Setting]
2103* LD Power Adjustment Adjusts the intensity of the laser for the copier,
printer, and fax unit. The Copier and Printer/Fax
settings can be adjusted separately.
DFU
1* LD1 (Copier)
2* LD2 (Copier)
(–55~+64 / –20 /1 LSB step)
Approx. 50/128 = .4%
3* LD1 (Printer, FAX)
4* LD2 (Printer, FAX)
5* LD1 Adjustment Start/End
6* LD2 Adjustment Start/End
(–50~ –35 / –5 /1 LSB step)
2109* LD Beam Pitch Adjustment Adjusts the beam gap for the dual beam system.
After replacing the LD unit or replacing or clearing
the NVRAM, use this SP mode to adjust the laser
beam pitch.
This adjustment is performed by specifying the
number of pulses to the stepper motor that will
adjust the angle of rotation of the LD unit from the
home position.
1* 400 dpi Adjusts the laser beam pitch value for 400 dpi
resolution.
400 dpi: [8~262 / 144 / 1 pulse step]
After replacing the LD unit or replacing or clearing
NVRAM, use this SP and SP2-109-3 to adjust the
laser beam pitch.
2* 600 dpi Adjusts the laser beam pitch value for 600 dpi
resolution.
600 dpi: [30~284 / 168 / 1 pulse step]
After replacing the LD unit or replacing or clearing
NVRAM, use this SP and SP2-109-4 to adjust the
laser beam pitch.
3* 400 dpi Initial Setting
Initializes the laser beam pitch for 400 dpi using the
value for SP2-109-1.
After entering a value for SP2-109-1, this SP must
be used.
4* 600 dpi Initial Setting
Initializes the laser beam pitch for 600 dpi using the
value for SP2-109-2.
After entering a value for SP2-109-2, this SP must
be used.
5* Auto Pitch Adjustment
Interval
Sets the interval for automatic laser beam pitch
adjustment.
[0 ~ 65535 / 1000 / 1 step]
When the number of times that the resolution has
been changed reaches this value, the laser unit
position is automatically corrected.
6 Current LD Unit Position Displays the current LD unit position (number of
pulses from home position). If this is different from
the value of 2-109-1 or 2-109-2, LD unit positioning
has failed.
