Maintenance and Troubleshooting

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 30 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.

Turn OFF the power of the printer.

Lift up the DK Roll cover by the tabs at the 

sides of the cover.

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.
