Clean inside the top cover of the printer to maintain better printing quality and help prevent problems. Also clean inside the top cover in the following situations to ensure optimal operation:

• If the printed surface or the underside (back) of the paper is dirty after printing
• After you have used up a roll
• After borderless printing
• After printing on small paper
• After printing on paper that generates a lot of cutting debris
• If you have replaced the roll
• After printing on paper that generates a lot of paper dust
• If the message Blue platen switch is dirty. is displayed

		If the platen inside the top cover becomes dirty, it may soil the underside (back) of the paper. We recommend cleaning the platen after borderless printing or printing on small spaper.
		If the ejection guide is dirty, it may soil the edge of the paper when the paper is cut. We recommend cleaning the ejection guide even if it does not appear dirty, because it may actually be covered with paper dust.

1. Open the top cover.
   
   
   
2. If paper dust has accumulated in the vacuum holes (a) on the platen or in the borderless printing ink grooves (b), use the cleaning brush (c) provided with the printer to wipe it away.
   

Do not touch the Linear Scale (a), Carriage Shaft (b), or Ink Tube Stabilizer (c). Avoid cleaning where the carriage is retracted, in position (d) or (e). This may damage the printer.

3. Using a damp cloth that you have wrung out completely, wipe away dirt or paper dust (debris from cutting) inside the top cover.
   Wipe away any ink residue and paper dust (debris from cutting) on the Top Cover Roller (a), all over the Platen (b), the Paper Retainer (c), the Borderless Printing Ink Grooves (d), the Ejection Guide (e), the blue Switch (f), the section around the right-side Borderless Printing Ink Grooves (g), and so on.
   
   

		Do not use a dry cloth to wipe inside the Top Cover. This may create a static charge, which may attract dust and affect the printing quality.
		Do not touch the clear sheet on the side of the Top Cover Roller. This may damage the roller.

4. Close the top cover.
