10.3 Internal Cleaning
The overall internal cleaning of the printer is important to help reduce the dust and other
contaminates residing in the printer that may attach to the Print Head or Drive Roller and
affect the printer’s performance. Refer to Figure 10-5 for common areas needing cleaned.
1. Remove any installed media.
2. Turn the printer power “OFF.”
3. Loosen captive screws (Figure 10-3) and remove the top cover from the printer.
4. Using the two Head Release Levers (Figure 10-4), unlatch and raise the Print Head.
5. Basic internal cleaning can be done using a combination of compressed air, soft-bristle
brushes; foam/cotton tipped swabs and/or lint-free cloths dampened in alcohol. Using
any combination of these materials, remove dust or other contaminants from the printer.
6. When finished, latch the Print Head completely and reinstall the Top Cover and media.
7. Turn the printer power “ON.”
