APPENDIX
Your QL-500/550 may need cleaning from time to time, particularly if you are using it in a dusty
environment.
Cleaning the Print Head
The DK Paper Roll used in the QL-500/550 is designed to automatically clean the print head. As the
DK Paper Roll passes over the head during printing or label feeding, the print head is cleaned. If
necessary, simply feed the DK Paper Roll using the FEED button to clean the print head.
Cleaning the Roller
Use a Cleaning Sheet to clean the roller as described in the following procedure.
Refer to Accessories on page 67 for details on purchasing Cleaning Sheets.

2
Hold the DK Roll compartment cover at the sides near
the front of the QL-500/550 and firmly lift up to open the
cover.

Maintenance
Only use Cleaning Sheets designed for the QL-500/550 to clean the roller.
Anything else may scratch or damage the surface of the roller.
Be sure to remove the DK Roll before cleaning the
roller. The roller cleaning function will not operate
correctly if the DK Roll is not removed.
