COPY SERVICE MODE
1-004 [Dev. Motor Speed] Development Drive Motor Speed
([Color], Process Speed, Paper Type), Paper Type -> N: Normal, TH: Thick
Adjusts the development drive motor speed for correcting color shifts at the leading
edge or trailing edge area.
Black Motor [K]: Adjusts fusing roller speed for the trailing edge area.
Color Motor [YMC]: Adjusts registration roller speed for the leading edge area.
NOTE:
• SP1-004-002 and 005 is for color mode. Fine adjustment for B&W mode can be
done with SP1-005-001 and 002.
• SP1-004-004 is for normal paper. Fine adjustment for thick paper can be done with
SP1-005-003.

1-005 [Dev. Motor Speed2] Development Drive Motor Speed 2
([Color], Process Speed, Paper Type), Paper Type -> TH: Thick
1-005-1 [K]
Adjusts the black development drive motor speed for the B&W 125mm/s process
speed. The value stored in this SP mode is different from SP1-004-002 (see the note
for SP 1-004).
At the 125mm/s process speed, the transfer unit position for B&W is different than for
color mode. The transfer unit position affects the paper transport quality, causing the
paper to flip up at the fusing section if the same speed as color mode is used for B&W
mode. To minimize the occurrence of paper flipping up, which causes smeared
images in the trailing area, this SP mode can change the motor speed in B&W mode.
1-005-2 [YMC]
Adjusts the color development drive motor speed for the B&W 125mm/s process
speed. The value stored in this SP mode is different from SP1-004-005 (see the note
for SP 1-004).
At the 125mm/s process speed, the transfer unit position for B&W is different than for
color mode. The transfer unit position affects the paper transport speed slightly. This
SP mode can adjust the motor speed for B&W mode.
1-005-3 [YMC] Thick
Adjust the color development drive motor speed for thick paper in by-pass mode. The
value stored in this SP mode is different from SP1-004-004 (see the note for SP 1-
004).
Normal and thick paper are different types of paper, and this sometime causes color
shift due to paper slippage. This SP mode can change the motor speed for thick
paper.
1-006 [Dev. Motor Speed3] Development Drive Motor Speed 3
([Color], Process Speed, Paper Type), Paper Type -> SP: Special
Adjusts the development motor speed for special paper.
1-006-1 [K] 62.5 Special
1-006-2 [K] 125 Special
1-006-3 [YMC] 62.5 Special
