  • Disconnect the USB cable from the computer before cleaning the machine.
  • Do not use tissue paper, paper towels, rough-textured cloth, or similar materials for cleaning so as not to scratch the surface.
  • Never use alcohol, thinner, benzene, etc. The exterior may deform, discolor, or dissolve.

With a soft dry cloth, wipe the platen (A), the inner side of the document cover (white sheet) (B), and the exterior (C). For stubborn dirt, clean with a well wrung damp cloth, then wipe off moisture with a soft dry cloth. Wipe thoroughly, especially the glass surface so as not to leave any residue.



  • Do not press the document cover or platen heavily. The glass may break and cause injury.
  • Wipe off moisture thoroughly. Scanning with moisture left on the glass surface and document cover may affect the image.
  • Do not wet the connectors or metal parts on the rear side of the machine. If they get wet, wipe them thoroughly with a dry cloth.
  • Do not wipe with a wet cloth that has not been wrung well or directly spray water or detergent onto the machine. Moisture may get inside the machine and adhere to the inner side of the platen or sensor, causing an image defect or malfunction.
