Cleaning Inside the Top Cover
Clean inside the Top Cover 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 of 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
Important
•
If the Platen inside the Top Cover becomes dirty, it may soil the underside of paper. We recommend
cleaning the Platen after borderless printing or printing on small paper.
•
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.
