SP MODES
ˆ
Many of these SPs are DFU, but this is how they work, anyway.
ˆ
2-301: Transfer current adjustments
¾
Paper has resistance. If the user changes to a thicker paper, an increase in
current may be necessary, because the paper resistance is higher.
¾
2301 001, 002: These are for the front and rear sides of duplex copying; the
service manual is not clear about this point.
¾
Note the different SPs for sides 1 and 2, and for the leading and trailing edge
areas.
¾
The leading and trailing edge areas are defined using SP 2931 to 2936.
ˆ
2931 to 2936: Transfer current on and off timing
¾
If the paper sticks on the drum at the leading edge, or will not separate at the
trailing edge, try adjusting the timing with this SP mode.
