Problem
An error occurs when the roll
cannot be fed to the beginning of
the printing.
Printer is in cooling mode.
I want to reset the printer/delete
the data transferred from the
computer.
Print head cannot be attached.
The media is not ejected correctly
when using the optional label
peeler.
Solution
If a feed error occurs, use the Paper Size Setup of the Printer Setting Tool to
assign the correct paper settings to the printer.
The thermal head is too hot.
The printer stops and resumes printing only after the thermal head has cooled
down. The thermal head may become too hot if you are printing a large number
of labels.
When the thermal head becomes too hot, it may produce imaging outside the
print area. To avoid or delay overheating, make sure the printer has adequate
ventilation and is not located in an enclosed space.
If the printer must cool down because it overheated due to the type of roll you are
using or the contents of the label, printing may take longer than usual.
NOTE
This condition may occur more often when the printer is used at high
altitude (more than 10,000 ft (3,048 m)) due to a lower air density
available to cool the printer.
See Related Information.
The print head cannot be attached if the print head spring is sticking out. Place
the print head spring correctly and try again.
Has the sensor of the label peeler been exposed to direct sunlight?
If the sensor of the label peeler has been exposed to direct sunlight, loaded
media may not be detected correctly. Use the printer in a location not exposed to
direct sunlight.
