Sub-item Description Level
TR-TP-LV Adjusting the level of transfer lead edge weak bias
1
<Setting range> -50 to 50 (Default: 0) (Unit: %)
If RAM on the DC controller circuit board has been cleared or the board itself has been replaced, enter the value from
the service label.
This mode is to set the voltage application level. The setting becomes enabled depending on the combination of the
following modes.
COPIER>OPTION>COMBO>PPR-SLCT/MOD-SLCT/ENV-SLCT/ TR-SW1 to 5<Adjustment method>
Enter the service label value when clearing RAM of the DC controller PCB or replacing the PCB.
This mode determines the level of applying weak bias to transfer lead edge.
The transfer lead edge weak bias becomes effective with the following settings.
1) Output condition: Execute 'COPIER>OPTION>COMBO> (1) PPR-SLCT (paper type) / (2) MOD-SLCT (paper
pick-up mode) / (3) ENV-SLCT (environment selection)' and register them under TR-SW 1 to 5.
2) Execute 'COPIER>ADJUST>HV-TR (1) TR-TP-TM (length of application time) / (2) TR-TP-LV (application
level).'
<Setting range> -50 to 50 (Default: 0) (Unit: %)
The following settings, however, have different ratios.
48: -60%
49: -80%
50: -100%
Example: Enter '-50'. -> -50% Enter '47'. -> 47% Enter '50'. -> -100%
(For DCON Ver.15.11 or later)
2TR-TGT1 to
2TR-TGT8 Setting an offset value for the paper sharing voltage in ATVC
2
<Setting range> -10 to 10
(Value at shipping: Factory adjustment value / Value after RAM clearance: 0)
TR-PPR1 to TR-
PPR8 Setting a paper type at ATVC setting
2
<Setting range> 1 to 8
(Value at shipping: Factory adjustment value / Value after RAM clearance: 0)
1: Plain paper (Default), 2: thick paper, 3: envelope, 4: tracing paper, 5: OHP transparency, 6: Postcard, 7: Label
paper, 8: Bond paper
TR-ENV1 to
TR-ENV8 Setting environment at ATVC setting
2
<Setting range> 1 to 3
1: Category A (low temperature) (Default), 2: Category B (room temperature), 3: Category C (high temperature)
TR-DUP1 to
TR-DUP8 Setting simplex paper feed mode at ATVC setting
2
<Setting range> 1to 4
1: Simplex (Default), 2: Auto duplex feed, 3: Multiple simplex feed, 4: Multiple duplex feed
COPIER > ADJUST > FEED-ADJ
Sub-item Description Level
REGIST Adjusting the registration roller clutch ON timing
1
<Setting range> -128 to 127 (Default: 0)
Increasing the value by 1 shifts the image 0.1 mm forward.
If RAM on the DC controller circuit board has been cleared or the board itself
has been replaced, enter the value from the service label.
LOOP-CST Adjusting the registration loop amount at cassette paper feed
1
<Setting range> -128 to 127 (Default: 63)
A higher setting will increase the degree of paper arching. (unit:0.1mm)
If RAM on the DC controller circuit board has been cleared or the board itself
has been replaced, enter the value from the service label.
LOOP-MF Adjusting the registration loop amount at cassette paper feed
1
<Setting range> -128 to 127 (Default: 45)
A higher setting will increase the degree of paper arching. (unit:0.1mm)
If RAM on the DC controller circuit board has been cleared or the board itself
has been replaced, enter the value from the service label.
ADJ-REFE Adjusting the horizontal registration at paper re-feed (Small paper)
- If the image is deviated to this side, increase the value.
1
<Setting range> -128 to 127 (Default: 0)
If RAM on the DC controller circuit board has been cleared or the board itself
has been replaced, enter the value from the service label.
LOOPREFE Adjusting the registration loop amount at duplex paper feed
1
<Setting range> -128 to 127 (Default: 45)
A higher setting will increase the degree of paper arching. (unit:0.1mm)
If RAM on the DC controller circuit board has been cleared or the board itself
has been replaced, enter the value from the service label.
