SP2 Mode Number Function and [Setting]
2912 01 Drum Reverse Rotation
Interval
Adjusts the time the drum and belt are reversed
in order to prevent paper dust and toner from
collecting at the blade. DFU
[0 ~ 10 /3 / 1 step]
Example 1: If you enter 3, then:
3/2 = 2 (rounded up) x 10 + 10 = 30 ms
Example 2: If you enter 10, then:
10/2 = 5 x 10 + 10 = 60. However, the limit is 50
ms so in this case, 60 ms is reduced to 50 ms.
2913* 01 Test Pattern Density
Sets the print density for the patterns printed
with SP2902-03. DFU
[0 ~ 15 / 15 / 1 ]
Process Control Setting Adjusts the charge roller voltage for the following
items.
01 C alpha Adjusts the charge roller voltage used when
paper with a small width is fed from the by-pass
tray. The paper width below which the correction
starts depends on the value of SP2309-01.
Use this SP when an image problem (such as
white spots at the center of black dots or breaks
in thin black lines) occurs when paper with a
small width is fed from the by-pass feed tray.
[0 ~ 400 / 150 / 10 V step]
02 C beta Adjusts the charge roller voltage used when
paper with a small width is fed from the by-pass
tray. The paper width below which the correction
starts depends on the value of SP2309-02.
Use this SP when an image problem
(☛ SP2914-01) occurs when paper with a small
width is fed from the by-pass feed tray.
[0 ~ 400 / 0 / 10 V step]
03 B gamma Adjusts the development bias used when paper
with a small width is fed from the by-pass tray.
The paper width below which the correction
starts depends on the value of SP2309-01.
Use this SP when an image problem
(☛ SP2914-01) occurs when paper with a small
width is fed from the by-pass feed tray.
[0 ~ 300 / 200 / 10 V step]
2914*
04 B delta Adjusts the development bias used when paper
with a small width is fed from the by-pass tray.
The paper width below which the correction
starts depends on the value of SP2309-02.
Use this SP when an image problem
(☛ SP2914-01) occurs when paper with a small
width is fed from the by-pass feed tray.
[0 ~ 300 / 50 / 10 V step]
2920 01 LD Off Check Used to confirm that the laser diode shuts off
when the cover is opened. DFU
2960* 01 Toner Overflow Sensor Selects whether the toner overflow sensor is
activated or not.
0 = No, 1 = Yes
