Title image shift to a corner
Explaination [Detailed explanation]
When copying an irregular original smaller than LETTER size via the DADF on to
LETTER size paper, the image shifts to a corner and cuts parts of the image.
[Field Remedy]
Since the original on the DADF is an irregular size and smaller than LETTER size, it
will not center the image on to a LETTER size paper. You would need to activate a
Special Features option on the Copy Screen called Long Strip Original. This mode is
not available in the Special Features tab on the Copy Screen unless it is activated via
service mode. The following is the service mode:
Level 2 under COPIER > OPTION > USER > MF-LG-ST = 1
This key sets the long length mode to be displayed and available under the Special
Features tab on the Copy Screen.
Once the mode is activated, you can set a shortcut for the function on the Copy
Screen via the User Mode in Additional Functions.
Additional Functions> Copy Settings> Standard Key 1 Settings for Regular Screen>
Long Strip Originals and then hit OK.
Title Fuser paper edge damage
Explaination [Detailed explanation]
To reduce the effects of paper wearing a groove into the pressure roller in the fixing
assembly.
[Field Remedy]
In level 1 Service Mode> COPIER> ADJUST> FEED-ADJ> REG-SLID.
The default setting is 3 for both the first and second sides. A lower value will increase
the fuser wear and may increase registration reliability. A higher value will reduce the
fuser wear and may reduce the registration reliability.
Title Reduction of time for adjusting solid and halftone density

Title Unfocused image appears in edge of margin of image
Explaination [Detailed explanation]
In a low humidity environment, when an image with high toner deposit amount is
printed with a new secondary transfer roller, unfocused image might occur in the edge
of the margin. When the similar symptom occurs, follow the steps below.
[Cause]
Assumed cause is lack of transfer current.
[Field Remedy]
1. Service Mode> COPIER> Display> ANALOG> ABS-HUM2, check the inside
moisture content.
2. Service Mode> COPIER> Adjust> HV-TR> 2TR-TGT1 to 8, corresponding to the
inside moisture content checked on the step 1, increase the value one step each
while checking the improvement at each step. As the value is changed by 1, current
is increased/decreased by 5uA.
0.63g/m3 or below : TR-TGT1
0.64 to 1.72g/m3 : 2TR-TGT2
1.73 to 5.79g/m3 : 2TR-TGT3
5.8 to 8.89g/m3 : 2TR-TGT4
8.9 to 14.9g/m3 : 2TR-TGT5
15 to 17.9g/m3 : 2TR-TGT6
18 to 21.5g/m3 : 2TR-TGT7
21.6g/m3 or above : 2TR-TGT8
[Reference]
If the transfer current is excessively increased, density loss due to excessive transfer
might occur.
