Troubleshooting
ProcedureCheck and measureYesNo
1

Check for the usage environment
Check that the operating environment is within the specifications.
*Refer to Printer Specifications Has the referred-to phenomenon occurred?


Go to step 2


  • Recommend using in an appropriate environment.
2

Check the paper

  • Check that there is no damage to the paper before it pases through.
  • Check that there is no curl, and that the paper is in a suitable condition.
  • Check that this is not preprinted.

* When, for example, A4 paper is used cut to A5 size, the long grain becomes the short grain so there is a tendency for edges to bend easily.

Make sure the appropriate paper has been used.

Go to step 3
  • Use suitable paper.
  • Use the rubbing avoidance mode.

* If the symptom continues even after using the rubbing avoidance mode, refer to the avoidance measures.


3

Check the feed path
Check that there is no damage to or foreign object on the feed path.


Go to step 4
  • Remove the foreign object and then clean.

If the symptom continues to occur, go to step 4.

4

Check the Star Wheel Assy

  • Check that the jagged roller of the Star Wheel Assy rotates normally.
  • Check that there are no cuts or other damage locally on the EJ Roller surface.
Go to step 5
  • Replace the Star Wheel Assy.

If the symptom continues to occur after replacement, contact the EPSON Service Department.

5

Check the PG
Check the PG with the thickness gauge and check that it is within the specified value range (1.55 ±0.10 mm).

Contact the EPSON Service Department.
  • Perform PG adjustment.

If the symptom continues to occur after performing the PG adjustment, contact the EPSON Service Department.

Avoidance measures

If the symptom continues even in the rubbing avoidance mode

  • Reduce the print density (default is -20 for duplex, but -5 or -10 from that).
  • Increase the drying time.
  • Make sure that a high density image does not come at the trailing edge of the first side (rotate, change the print order, etc.).
