● 146: Adjustment of the magnification to write image in laser's main
scanning direction (A-C)
Magnification between lasers A and C.
Amount of adjustment of the magnification of laser C of the laser scanner unit. Adjust the
magnification of laser C with reference to that of laser A. If the input value is inappropriate,
the image quality is degraded.
● 147: Adjustment of the magnification to write image in laser's main
scanning direction (A-D)
Magnification between lasers A and D.
Amount of adjustment of the magnification of laser D of the laser scanner unit. Adjust the
magnification of laser D with reference to that of laser A. If the input value is inappropriate,
the image quality is degraded.
● 148: Adjustment of the point to start writing in main scanning direction
(A-B)
When replacing the laser, enter the delay value (laser main scanning adjustment).
● 149: Adjustment of the point to start writing in main scanning direction
(A-C)
When replacing the laser, enter the delay value (laser main scanning adjustment).
● 150: Adjustment of the point to start writing in main scanning direction
(A-D)
When replacing the laser, enter the delay value (laser main scanning adjustment).
● 151: Developing bias offset for DC
Enter the developing bias offset for DC.
When a fault in image occurs (foggy image or light density), enter the developing bias offset
for DC. Increasing the value makes the image darker.
● 152: Primary charge offset for DC
Enter the value to adjust the primary offset 1 for DC.
● 153: Primary charge offset for AC
Enter the value to adjust the primary offset 1 for AC.
● 154: Adjustment of the registration loop volume (Thick paper)
Incrementing the value by 1 feeds the paper 0.1 mm further and increases the registration
loop volume.
● 155: Adjustment of the registration loop volume (Special paper)
Incrementing the value by 1 feeds the paper 0.1 mm further and increases the registration
loop volume.
● 156: Adjustment of the registration loop volume (Envelop cassette
pickup)
Incrementing the value by 1 feeds the paper 0.1 mm further and increases the registration
loop volume.
● 157: Pickup timing adjustment
This setting is applied to the pickup permission temperature at job start irrespective of
the fixing mode. The pickup permission temperature is raised or lowered from the default
temperature according to the setting value.
Use this parameter to reduce the FCOT or warm-up time.
0 - 2: +15˚C
3 - 11: +12 to -15˚C (in steps of 3˚C)
12 - 14: -15˚C
● 165: Fixing auto cleaning frequency setting
Use this parameter to increase the fixing auto cleaning frequency. Incrementing the value
increases the fixing auto cleaning frequency.
0: Not cleaned.
1: Cleaning control temperature: 225˚C, Cleaning time: 60 sec, Cleaning interval: 500 sheets
2: Cleaning control temperature: 225˚C, Cleaning time: 60 sec, Cleaning interval: 200 sheets
3: Cleaning control temperature: 225˚C, Cleaning time: 60 sec, Cleaning interval: 100 sheets
● 166: Temperature adjustment UP/DOWN mode (Plain paper, manual
feed tray)
The temperature adjustment offset relative to the target fixing temperature of plain paper fed
from the manual feed paper can be changed in steps of 3˚C. Use this parameter when the
fixing performance is low or when it is necessary to prevent the paper from slipping or being
curled.
Plain paper: Plain paper mode, thin paper mode, S thin paper mode, OHP mode
0 - 2: +15˚C
3 - 11: +12 to -15˚C (in steps of 3˚C)
12 - 14: -15˚C
