36STEP 3 Maintenance and Troubleshooting
1 Maintenance
Maintenance of the printer needs only to be done when required. However, some environments will require that maintenance should be done more frequently (e.g. in dusty conditions).
Print head maintenance
The DK Roll (thermal recording paper type) used with the printer is designed to clean the print head automatically. When the DK Roll passes the print head during printing and label feeding, the print head is cleaned.
Roller maintenance
Clean the roller using the cleaning sheet (available separately). The printer contains only one cleaning sheet.
When doing maintenance on the roller, be sure to use the cleaning sheet supplied exclusively for this printer.
If using other cleaning sheets, the surface of the roller may be damaged and may cause a malfunction.
1 Turn OFF the power to the printer.
2 Hold the DK Roll compartment cover at the sides near the front of the printer and firmly lift up to open the cover.
3 Pull up the roll release lever and remove the DK Roll.
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.
