Cleaning Inside the Printer (Bottom Plate Cleaning)
Remove stains from the inside of the printer. If the inside of the printer becomes dirty, printed paper may get
dirty, so we recommend performing cleaning regularly.
You need to prepare: a sheet of A4 or Letter-sized plain paper*
* Be sure to use a new piece of paper.
1. Make sure that the power is turned on and remove any paper from the rear tray.
2. Prepare paper.
1. Fold a single sheet of A4 or Letter-sized plain paper in half widthwise, then unfold the paper.
2. Load only this sheet of paper in the rear tray with the open side facing you.
3. Pull out the paper output tray and the output tray extension.
3. Hold down the Stop button until the Alarm lamp flashes eight times, then release it
immediately.
The paper cleans the inside of the printer as it feeds through the printer.
Check the folded parts of the ejected paper. If they are smudged with ink, perform Bottom Plate Cleaning
again.
Note
• When performing Bottom Plate Cleaning again, be sure to use a new piece of paper.
