2TR-N1 Sec trn ATVC ppr allot V:pln1 1st,L-hmdy
Lv.1 Details To adjust the paper allotted voltage for the 1st side of plain paper 1
in secondary transfer ATVC control at low humidity.
When transfer failure occurs on an image, adjust the value in the -30
to 30 (-900 to 900V) range in increments of 10 (30V).
When white dots occur on an image, the image failure can be
alleviated by adjusting the value in the -100 to -10 (-3000 to -300V)
range in increments of 10 (30V). However, if the value is too small,
transfer failure occurs.
Use case When adjusting the secondary transfer bias according to conditions
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Display/adj/set range -128 to 127

in secondary transfer ATVC control at low humidity.
When transfer failure occurs on an image, adjust the value in the -30
to 30 (-900 to 900V) range in increments of 10 (30V).
When white dots occur on an image, the image failure can be
alleviated by adjusting the value in the -100 to -10 (-3000 to -300V)
