STEP4 Maintenance and Troubleshooting 52
Maintenance of the printer must be done as needed. However, some environments
require that maintenance must be done more frequently (e.g. in dusty conditions).
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.
Clean the roller using the cleaning sheet (separately available).
the printer contains only one cleaning sheet. To purchase additional cleaning sheets,
refer to Î "Accessories (For USA Only)" in page 58 as needed.
When doing maintenance on the roller, be sure to use the cleaning sheet exclusive
for this printer only.
If using other cleaning sheet, the surface of roller may be scratched or it may cause
a malfunction.
