1TR-TGY Y pry trn ATVC tgt crrnt:pln/rcycl1,2
Lv.2 Details To adjust the offset of the target current value for Y-color upon
primary transfer ATVC control for plain paper 1, 2/recycled paper 1, 2
(which paper width is A4 or larger).
Increase the value when spots, mottled image, or image failure due
to insufficient transfer current occurs.
Decrease the value when image fogging due to transfer memory or
drum memory due to strong transfer current occurs.
Use case When an image failure due to the primary transfer occurs
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Display/adj/set range -50 to 50
Unit 1 uA
Default value 0

(which paper width is A4 or larger).
Increase the value when spots, mottled image, or image failure due
to insufficient transfer current occurs.
Decrease the value when image fogging due to transfer memory or
drum memory due to strong transfer current occurs.

upon primary transfer ATVC control for plain paper 1, 2/recycled
paper 1, 2 (which paper width is A4 or larger).
Increase the value when spots, mottled image, or image failure due
to insufficient transfer current occurs.
Decrease the value when image fogging due to transfer memory or
drum memory due to strong transfer current occurs.

Lv.2 Details To adjust the offset of the target current value for Bk-color (color)
upon primary transfer ATVC control for plain paper 1, 2/recycled
paper 1, 2 (which paper width is A4 or larger).
Increase the value when spots, mottled image, or image failure due
to insufficient transfer current occurs.
Decrease the value when image fogging due to transfer memory or
drum memory due to strong transfer current occurs.

2TR-OFF Uniform adj sec trn ATVC ppr allot voltg
Lv.1 Details To uniformly adjust paper allotted voltage in secondary transfer ATVC
control regardless of paper type, 1st/2nd side or environment.
When transfer failure occurs on an image, increase/decrease the
value in the -30 to 30 (-900 to 900 V) range in increments of 10 (30 V).
When white dots occur on an image, increase/decrease the value in
the -100 to -10 (-3000 to -300 V) range in increments of 10 (30 V).
When the value is decreased too much, transfer failure occurs.
Use case When similar image failures occur regardless of the conditions
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Caution The setting is applied to all paper types and both sides of paper.
When limiting the condition, be sure to make settings individually.
Display/adj/set range -128 to 127
