then gently pull the jammed
paper out of the unit.
• Condensation collected in unit?
t If the unit has just been brought
into a warm room from a cold
location, condensation may have
formed inside the unit. Switch
the unit off and let it set for 1 - 2
hours (until it warms to room
temperature), then try printing
again.
Printouts dirty. • Thermal head dirty?
t
Use the head cleaning sheet
provided with the unit to clean
the thermal head. (page 24)

The unit stops printing
while printing almost
black images
continuously and the
message “COOLING”
is displayed on the
LCD. When printing almost black images
continuously, the thermal head
protection circuit may shut down the

Printing is interrupted.
When printing, the
unit discharges several
centimeters of the
white paper and stops.

cannot be performed.
The FEED operation
cannot be performed.
When the paper is set
correctly, “EMPTY” is
displayed. Does the sunlight or incandescent light
that includes strong infrared light
irradiate the paper exit?
t The unit has an infrared light sensor
that detects the printing paper.
Therefore, when the light directly
irradiates the paper exit, paper
detection may not operate correctly.
Do not expose the paper exit to
light directly.
