*: model equipped with DADF-Q1 (outside Japan: iR7105/7095; inside Japan: All model).
**: model equipped with DADF-M1 (outside Japan: iR7086).
***: up graded version
Sub item
OHP-CNT Use it to enable/disable the transparency mode potential control mechanism.
settings
0: use the target value obtained from transparency mode (default)
1: do not execute potential control during transparency mode (Use potential control for plain paper mode)
How to use:
In the transparency mode, change as '1' if the density is light. (Use charging control for plain paper mode)
-This is not used for servicing normally.
-Potential control for transparency mode is normally used for transparency/intermediate paper/postcard
FIX-TMP1 Use it to select a start temperature for plain paper down sequence.
If the user places priority on image quality, set it to '0'; on speed, to '2'.
settings:
0: 183 deg C; 1:178 deg C (default); 2: 173 deg C
How to use:
When prioritizing image quality (fixing performance), select '0'. When prioritizing speed (productivity), select '2'.
TRSW-P-B Use it to enable/disable the transfer current output correction mechanism for the trail edge of paper.
As a remedy for transfer fault that occurs in case of large degree of lower curl of paper, decrease the transfer current onto the trailing
edge of the paper.
Settings
0: ON 1: OFF (default)
When setting as '0', transfer current onto the trailing edge of paper is changed as follows:
1-sided print (1-sided print, 1st side of 2-sided print)
Decrease by 220 uA in the low humidity environment (absolute moisture content: 5g or less)
Decrease by 150 uA in the normal humidity environment (absolute moisture content: 5.01-17.99g)
No change in the high humidity environment (absolute moisture content: 18g or more)
2-sided print (2nd side of 2-sided print)
No change for Low/Normal/High environment
Remarks
This is not used for servicing normally.
SP-MODE Separation voltage (Vpp) output offset ON/OFF control
Decrease separation voltage as a remedy for separation voltage leak that occurs in low-pressure environment such as high altitude
area.
Settings
0: standard mode (10KVpp) (default) 1: low voltage mode (9KVpp)
FTMP-DWN Select finisher loading capacity improvement mode (the mode to decrease degree of curl)
This setting value (setting temperature) becomes effective on and after 1000th-delivered sheet.
settings
0: off (default); 1: -5 deg C; 2: -10 deg C; 3; -15 deg C
MEMO:
This is not used for servicing normally.
When decreasing the fixing temperature for the purpose of decreasing the degree of curl, COPIER > OPTION > BODY > TEMP-
TBL is recommended
DRUM-CLN Use it to select an appropriate drum cleaning performance enhancement mode (stop sequence).
- use it if cleaning faults occur.
- during copying, stops the rotation of the drum for 1 sec when the setting is reached, recovering the cleaning performance of the
cleaning blade.
- the higher the setting (0 to 3), the more effective it is.
settings
0: if single-sided, 1,000 prints; if double-sided, 500 prints (default)
1: if single-sided, 500 prints; if double-sided, 250 prints
2: if single-sided, 250 prints; if double-sided, 125 prints
3: at absolute moisture content of 9 g or more, if single-sided, passage of 1,000 prints/if double-sided, of 500 prints
at absolute moisture content of less than 9 g, if single-sided, passage of 250 prints/if double-sided, of 125 prints
4: off (do not stop drum rotation)
