What to do if my Epson Perfection 4490 Photo Scanner image quality is poor?
- J
  Johnny HernandezAug 3, 2025
  If you are experiencing poor image quality with your Epson Scanner, it could be due to a few reasons. If the image has white spots, the Document Glass might not be clean, so clean the glass. If vertical bands appear on the image, the mirror in the Carriage might not be clean, so clean the mirror. If the white document mat is deformed or not clean, the Upper Housing may have failed, so replace the Upper Housing. A CCD Sensor Board failure will also cause this, so replace the Carriage Unit. Main Board failure also causes this, so replace the Main Board. Finally, Carriage mechanism failure may be the cause, so replace the Carriage mechanism.

The SUB_C Board and the SUB_D Board may have failed, so replace the SUB_C Board and the SUB_D Board. DRV Board failure may be the cause, so replace the DRV Board.

  If the fluorescent lamps on your Epson Scanner are not lit, it could be due to a few reasons. First, Connector CN1 on the Main Board might not be connected, or Connectors CN1 and CN2 on the CCD Board might not be connected, so connect the disconnected connectors. Second, the lamp might not be set on the Inverter Board correctly, so set the lamp on the board correctly. Third, the Carriage Unit may have failed because the Carriage FFC is not connected to the Main Board and the Carriage, so replace the Carriage Unit.
