Mode No.
(Class 1, 2, and 3)
Function / [ Setting ]
[Dev. Mt Speed2] Development Drive Motor Speed 2
([Color], Process Speed, Paper Type), Paper Type -> TH: Thick
1 [K] 125 * 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.
[ -0.2 to 1.0 / 2 / 0.1 %/step ]
2 [YMC] 125 * 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.
[ -1.0 to 1.0 / 0 / 0.1 %/step ] FA
005
3 [YMC] 62.5 TH * 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.
[ -0.3 to 0.3 / 0 / 0.1 %/step ]

4 [YMC] 125 SP *
Adjusts the development motor speed for special
paper.
