Troubleshooting
Symptom Confirmation and action Correspondence after confirmation

Image defect 1

Black line soiling

Check the following part for contamination:

  • ADF Unit
    • Check the contamination of the ADF reading part (ADF CIS module part).
      [Measure] Clean the glass surface of the ADF/scanning glass.
  • SCN Unit
    • Check the contamination of the SCN glass surface.
      [Measure] Clean the ADF scan glass surface.

If the symptom continues to occur after cleaning, replace the ADF/SCN Unit (refer to ADF/SCN Unit  ) because one of the CIS modules of the ADF/SCN Unit may be broken.
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

  2. Check the scanner cable connection.
    [Measure] Reconnect the Scanner cable correctly.

  3. If the scanned document and size recognized on the printer side do not match, replace the ADF/SCN Unit.

If the symptom continues to occur after performing the procedure given in the left column, replace the ADF/SCN Unit (refer to ADF/SCN Unit) because one of the CIS modules of the ADF/SCN Unit may be broken.

If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

Image defect 4

Image skewed on paper (only when ADF)
(Image skewed only when copying)

Check that the height of the ADF is appropriate in relation to the scanning glass.
Check that the ADF is attached parallel to the scanning glass.
  • Replace the hinges. (ADF/SCN Unit)

  • If the ADF position is offset from the scanning glass even after replacing the hinges, replace the ADF/SCN Unit. (refer to ADF/SCN Unit)

(If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.)

Image defect 5

Other print quality problems occurred only when copying
  1. Check the contamination of ADF/SCN glass surface.
    [Measure] Clean the glass surface of the ADF/scanning glass.
  2. Check the scanner cable connection.
    [Measure] Reconnect the Scanner cable correctly.

If the symptom continues to occur after performing the procedure given in the left column, replace the ADF/SCN Unit (refer to ADF/SCN Unit) because one of the CIS modules of the ADF/SCN Unit may be broken.
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

Feed defect 1

Double feeding

 Clean the ADF Pickup Roller Assy/ADF Pad.

If the symptom continues to occur after performing the procedure given in the left column, replace the ADF Pick Up Roller (refer to ADF Pick Up Roller) and the ADF Pad (refer to ADF Pad Assy).
(If the symptom continues to occur after replacing the ADF Pickup Roller and ADF Pad, replace the ADF/SCN Unit. (refer to ADF/SCN Unit) If the trouble is not resolved, inquire at service support)

Feed defect 2

Document bending

Check that there is no foreign object or damage in the ADF feed path.
[Measure] Remove the foreign object if any.

If the symptom continues to occur after performing the procedure given in the left column or there is damage in the ADF feed path, replace the ADF/SCN Unit. (refer to ADF/SCN Unit)
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

Feed defect 3

Paper jam occurs when feeding from the ADF
  • Check that the ADF is closed correctly.
  • Check that the height of the ADF is appropriate in relation to the scanning glass.
  • Clean the ADF feed path.
  • Clean the feed roller surfaces.

Replace the ADF/SCN Unit. (refer to ADF/SCN Unit)
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.
