5.7.10 SP6-40: INK DETECTION ADJUSTMENT
Ensures that the CPU detects a no ink condition.
CAUTION: 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 u” (4 µs).
NOTE: When the drum has ink inside, the machine displays “----“.
