CHANGE IN PROCESS CONTROL PWB TO IMPROVE
SERVICABILITY .
1.Model name: SD-2060
2.General: The rough adjustment volume has been added to the fine adjustment volume in the
process control PWB in order to facilitate the adjustment of the drum marking sensor
and process control sensor.
3. Description: A change in volume resistance (VR 1, VR 2), an addition of volume resistance (VR 3,
VR 4) and a change in R5 have been carried out (Refer to Page 2).

Process Control PWB Adjustment
1. Drum marking sensor adjustment procedure.
➀ Turn VR 3, VR 4 as far to the left (counter clock-wise) as possible.
➁ Input Sim 44 - 02.
➂ Adjust fine adjustment volume VR 3 to 170 ±10.
➃ If after performing step ➂ above the VR 3 adjustment range does not rise even after
turning it as far to the right as possible, return VR 3 as far to the left as possible, and
adjust the rough adjustment volume VR 4 to between 105 and 160.
➄ Adjust VR 3 to 170 ±10.
2. Process control sensor adjustment procedure.
➀ Turn VR 1, VR 2 as far to the left as possible.
➁ Input Sim 44 - 03.
➂ Adjust the fine adjustment volume VR 1 to 815 ±15.
➃ If after performing step ➂ above the VR 1 adjustment range does not rise even after
turning it as far to the right as possible, return VR 1 as far to the left as possible, and
adjust the rough adjustment volume VR 2 to between 673 and 800.
➄ Adjust VR 1 to 815 ±15.
