This solution is performed if some SP modifications are needed in Solution (2: Custom Paper Settings)
.
First we must do is specifying the roller that causes this issue.
Check |
To do when the check is YES |
|---|---|
Does the issue occur in face-up paper exit (normal paper exit)? |
SP1-013-001 through -041 |
Does the issue occur in both inverting (face-down) and duplex printing? |
Adjust all the SPs below as a set. SP1-007-001 through -041 SP1-008-001 through -041 SP1-009-001 through -041 |
Does the issue occur in only duplex printing? |
SP1-009-001 through -041 |
None of the above is applicable. |
Adjustment through SP (Scratches/Streaks on Side 2)
Take a note of the initial value of SPs that adjustment is needed.
Adjust the value of SPs applicable by -0.1% step.
If the issue occurs in both inverting (face-down) and duplex printing, adjust all the items in SP1-007/008/009 by -0.1% step.
Print the target paper.
Does the scratch/streak disappear?
Yes: Finished.
No: Repeat the step 2 through step 4. If some improvements are found with adjusting the values until -1.0%, then keep adjusting them. If no improvement can be found, there may be other causes. Restore the values to the value you took a note in step 1, and then, see other troubleshooting.
If the issue is found in both inverting (face-down) and duplex printing, restore the value to the value you took a note in step 1, and then go to the next step.
Adjust value of SP1-008, and SP1-009 by -0.1% (Do not change SP1-007s).
Print the target paper.
Is the problem solved?
Yes: Finished.
No: Repeat the step 5 through step 7. If some improvements are found with adjusting the values until -1.0%, then keep adjusting them. If no improvement can be found, there may be other causes. Restore the value to the value you took a note in step 1, and then, see other troubleshooting.
Adjustment through SP (Scratches/Streaks or Creases appear on Side 1)
Take a note of the initial value of SPs that adjustment is needed.
Adjust the value of SPs applicable by +0.1% step.
If the issue occurs in both inverting (face-down) and duplex printing, increase all the items in SP1-007/008/009 by +0.1% step.
Print the target paper.
Is the problem solved?
Yes: Finished.
No: Repeat the step 2 through step 4. If some improvements are found with adjusting the values until +1.0%, then keep adjusting them. If no improvement can be found, there may be other causes. Restore the value to the value you took a note in step 1, and then, see other troubleshooting.
