STEP3 Maintenance and Troubleshooting 48
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 (available separately).
The printer contains only one cleaning sheet. To purchase additional cleaning sheets,
refer to Î "Accessories (For USA Only)" on page 58 as needed.
When doing maintenance on the roller, be sure to use the cleaning sheet designed
for this printer only.
If using other cleaning sheets, the surface of roller may become scratched and cause
it to malfunction.
1
Turn OFF the power of the printer.
2
Lift up the DK Roll cover by the tabs at the
sides of the cover.
3
Pull up the roll release lever and remove the
DK Roll.
Before cleaning the roller, it is necessary to remove
the DK Roll. Otherwise, the roller cleaning function
does not function properly.
