SP6-40: Ink detection adjustment
Ensures that the CPU detects a no ink condition.
• Before attempting this procedure, wipe off the ink around the ink roller. To do this, set SP2-10 (ink
detection) to OFF, and feed paper until ink ends. After finishing the procedure, do not forget to return
SP2-10 to the default (ink detection on).
Access SP6-40, and open the door cover. Then turn the VR1 [A] on the MPU board until the display
becomes "4.0 ± 0.2 " (4 s).
• When the drum has ink inside, the machine displays "----".
SP6-100 to 104: Paper registration - each speed

130 rpm)

registration position).

2. Make 3 copies at speed 3 (finishing with 130 rpm). Perform the adjustment below for all 3 copies.
