The scanner surface should be cleaned after 10 000 documents or every three
months or whenever image quality deteriorates.
1. Open the ribbon cover. See Figure34.
2. Move the impact print head to its rightmost position, as shown.
3. Rotate the scanner registration plate 180° up to expose the glass scanner
surface. See Figure 34.
4. Use a cotton swab that is lightly soaked with alcohol to wipe any residue from
the scanner glass surface.
5. Gently return the scanner registration plate to its original position.
6. The scanner should be recalibrated after it has been cleaned. See “Document
scanner calibration (Models TI8, TI9, TG8, TG9)” on page 60.
