ADF/scanner trouble

Cause

  • Does not occur during printing (printing from a PC) and occurs only when copying from the ADF or scanning glass.

Suspected cause
  • Glass dirty
  • Scanning sensor dirty
  • Feed path roller dirty/deteriorated
  • Feed path foreign object
  • Feed path foreign object/damaged

  • CIS Module failure

Troubleshooting
Symptom Check and measure Correspondence after confirmation

Image defect 1

Black line soiling
  • ADF Unit
    • Check the contamination of the ADF scan glass surface / ADF reading part.
      [Measure] Clean the ADF scan glass surface/ADF reading part.
  • SCN Unit
    • Check the contamination of the SCN glass surface.
      [Measure] Clean the ADF scan glass surface.

If the problem still occurs after cleaning, the CIS module in the ADF/SCN Unit may be faulty, so replace the CIS Unit (CIS Unit (ADF), CIS Unit (SCN)), ADF Unit (see ADF unit ), and SCN Unit (see SCN Unit) one after the other, and check the status after each replacement.
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

If the surface of the scanner glass is scratched, replace the glass of the scanner glass.

Image defect 2

Some or all of an image is not scanned
  1. Check the glass surfaces of the ADF/scanner glass and each sensor for dirt.
    [Measure] Clean the glass surface of the ADF/scanning glass.
  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 SCN Unit.

If the problem still occurs after cleaning, the CIS module in the ADF/SCN Unit may be faulty, so replace the CIS Unit (CIS Unit (ADF), CIS Unit (SCN)), ADF Unit (see ADF unit), and SCN Unit (see SCN Unit) one after the other, and check the status after each replacement.
If the error continued after replacing the ADF/SCN Unit, contact the Epson Service Support department.

Image defect 3

Light
  • Scanning (CIS sensor) + glass back side dirty?
    Clean the corresponding parts.
  • When scanning both sides, if one side is light.
    Perform 60201 Shading Calibration (Back)

If the problem persists even after taking the measures described at left, perform the60201 Shading Calibration (Back) and 60202 Density Calibration in the Service Support Mode.

If the problem still occurs after adjustment, the CIS module in the ADF/SCN Unit may be faulty, so replace the CIS Unit (CIS Unit (ADF), CIS Unit (SCN)), ADF Unit (see ADF unit), and SCN Unit (see SCN Unit) one after the other, and check the status after each replacement.
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 installed parallel to the scanner glass using the ADF tilt check jig.

If the ADF is not parallel to the scanner glass, replace the ADF Unit (see ADF unit).

If the problem still occurs after replacing the ADF Unit, contact Epson local service representatives.

Image defect 5

Image defects other than the above that occur only when copying
  1. Check the contamination of ADF/SCN glass surface.
    [Measure] Clean the ADF/SCN glass surface.
  2. Check the Document Mat Cover for dirt.
    [Measure] Clean the Document Mat Cover or replace it.
  3. Check the scanner cable connection.
    [Measure] Reconnect the Scanner cable correctly.

If the problem still occurs after performing the procedure given in the left column, the CIS module in the ADF/SCN Unit may be faulty, so replace the CIS Unit (CIS Unit (ADF), CIS Unit (SCN)), ADF Unit (see ADF unit), and SCN Unit (see SCN Unit) one after the other, and check the status after each replacement.
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 Retard Roller.

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

Feed defect 2

Document bending
  1. Check that there is no foreign object or damage in the ADF feed path.
  2. Check the ADF/SCN Board for cable connection.
    [Measure] Reconnect the cable.

If any damage to parts is found after cleaning the ADF feed path, replace the damaged parts or the ADF Unit. (see ADF unit)
If the error continued after replacing the ADF 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 document feed path, sensors, and reflectors of the ADF Unit. (see ADF/SCN Unit)
  • Clean the feed roller surfaces.

Replace the ADF Pick Up Roller Assy (see ADF Pick Up Roller Assy ) and ADF Retard Roller (see ADF Retard Roller).
(If the symptom continues to occur after replacing the ADF Pickup Roller and ADF Retard Roller, replace the ADF Unit. (see ADF unit) If the trouble is not resolved, inquire at service support)
