1TR-TGY Y pry trn ATVC tgt crrnt:pln/rcycl1,2
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
Start key.
Display/adj/set range -50 to 50
Unit 1 uA
Default value 0
1TR-TGM M pry trn ATVC tgt crrnt:pln/rcycl1,2
Details To adjust the offset of the target current value for M-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
Start key.

Details To adjust the offset of the target current value for C-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

1TR-TGK1 Bk-m pry trn ATVC tgt crrnt:pln/rcycl1,2
Details To adjust the offset of the target current value for single Bk-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

1TR-TGK4 Bk-c pry trn ATVC tgt crrnt:pln/rcycl1,2
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.
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
Start key.

Unit 1 uA
Default value 0
2TR-OFF Uniform adj sec trn ATVC ppr allot voltg
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
Start 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
Unit 30 V
