STEP4 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.
