Scanner Maintenance includes scanner cleaning and calibration. You may complete these two steps to ensure the scanned images quality.
Paper powder, dust, ink and toner from paper being scanned may make the inner ADF dirty, which leads to poor image quality or document-feeding errors. When this happens, it’s time for scanner cleaning!
Before cleaning the scanner, please turn off the scanner and disconnect the scanner’s power cable and USB cable. And wait a few minutes for the glass and/or the inner ADF to cool to ambient temperature. Please clean the scanner with the cleaning cloth comes with the scanner, or other lint-free cloth.
After the cleaning is completed, please calibrate the scanner with the calibration sheet to adjust the color difference. Until now, the scanner maintenance is finished.
