OFSTAC-M Adj M charge AC voltage (1/1 speed)
Lv.1 Details To adjust the offset of the charge AC voltage for M.
As the value is incremented by 1, the voltage value is increased by
20 Vpp.
Decrease the value when image smear occurs, and increase the
value when image failure (sand-like image) occurs.
Use case • When image smear occurs
• When an image failure (sand-like image) occurs
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Caution • Do not use this when the machine is operating correctly.
• Use OFSTAC-M only when image failure is not alleviated by
making adjustment with DIS-TGM. In this case, be sure to return
DIS-TGM to its original setting.
• If the value is too large, the life of the Photosensitive Drum
becomes shorter.

OFSTAC-C Adj C charge AC voltage (1/1 speed)
Lv.1 Details To adjust the offset of the charge AC voltage for C.
As the value is incremented by 1, the voltage value is increased by
20 Vpp.
Decrease the value when image smear occurs, and increase the
value when image failure (sand-like image) occurs.
Use case • When image smear occurs
