Sub item
ACFRQNY Use it to set the developing AC bias frequency (remedy for retransfer/fogging; for plain paper and other papers).
Set the developing AC bias frequency for other papers than recycled paper/thin paper/thick paper.
Varies the developing AC bias frequency to adjust the level of fogging.
- if retransfer is too noticeable, decrease the setting (i.e., increase the level of fogging).
- if fogging is too noticeable, increase the setting.
settings:
-5: 2.0KHz -4: 2.1KHz -3: 2.2KHz -2 :2.3KHz -1: 2.4KHz 0: 2.5KHz (default)
Usage:
- Make the value smaller at re-transfer occurrence (Increase the fogging amount).
- When decreasing the fogging amount, increase the value.
1: 2.6KHz 2: 2.7KHz 3: 2.8KHz 4: 2.9KHz 5: 3.0KHz
MEMO:
The foregoing settings are valid only if '0' is set for the following: COPIER > OPTION > BODY > TR-SP-C1/C2/C3/C4/MF/DK.
CNT-TMG Use it to switch over the counter increment specifications when a delivery accessory is in use.
Use it in order to change the timing of accounting count-up in the case that several delivery options are connected.
settings
0: increase count upon delivery of paper from delivery accessory (default); 1: increase count upon delivery of paper from host
machine
1: Count-up at the time of delivery from the machine body
ACFRQ-R Use it to set the developing AC bias frequency (remedy for retransfer/fogging; for recycled paper).
Set the developing AC bias frequency for the paper on the setting of recycle paper/thin paper.
Varies the developing AC bias frequency to adjust the level of fogging.
Usage:
- if retransfer is too noticeable, decrease the setting (i.e., increase the level of fogging).
- if fogging is too noticeable, increase the settings.
settings
-5: 2.0KHz -4: 2.1KHz -3: 2.2KHz -2 :2.3KHz -1: 2.4KHz 0: 2.5KHz (default)
1: 2.6KHz 2: 2.7KHz 3: 2.8KHz 4: 2.9KHz 5: 3.0KHz
MEMO:
The foregoing settings are valid only when '0' is set for the fogging: COPIER > OPTION > BODY > TR-SP-C1/C2/C3/C4/MF/DK.
ACFRQ-T Use it to set the developing AC bias frequency (remedy for retransfer/fogging; for heavy paper).
Varies the developing AC bias frequency to adjust the level of following.
Usage:
- if retransfer is too noticeable, decrease the setting (i.e., increase the level of fogging).
- if fogging is too noticeable, increase the setting.
settings
-5: 2.0KHz -4: 2.1KHz -3: 2.2KHz -2 :2.3KHz -1: 2.4KHz 0: 2.5KHz (default)
1: 2.6KHz 2: 2.7KHz 3: 2.8KHz 4: 2.9KHz 5: 3.0KHz
MEMO:
The foregoing settings are valid only when '0' is set for the following: COPIER > OPTION > BODY > TR-SP-C1/C2/C3/C4/MF/DK.
K-DOT Selection of the drum separation faulty (re-transfer/leading edge white spot) remedy mode
Selects a mode in which minute dots are formed over the entire surface of the print (outside the image) as a remedy for retransfer.
A higher setting will decrease the level of retransfer.
Usage:
The larger the value, the larger the dot ratio (fogging amount). It is effective for re-transfer.
When reducing the fogging amount, use COPIER>OPTION>BODY>ACFRQNY/ACFRQ-R/ACFRQ-T.
settings
0: off (default); 1: 1-dot/75% frequency; 2: 1-dot/100% frequency; 3: 1 to 1.5-dot/100% frequency; 4: 1.5-dot/75% frequency
This item is valid only when a type of paper other than heavy paper has been selected.
MEMO:
- Do not use for servicing.
- This item is effective only when the paper other than thick paper was designated.
