Nothing can be printed with ERROR LED ON
– Check the Paper Out LED.
If it is ON, most probably either the paper roll is not installed or the paper roll
is at or near the end. Install a new paper roll. If the Paper Out LED is OFF,
please check if the print hood is properly closed. There are 2 internal
checkpoints inside the printer to assure the locking of the hood for a decent
printing.
Therefore any dislocation of the hood may cause an error status and inhibition
to printing.
Press down the hood at middle of the opening
when closing it

If there is no paper jam and the print head is not overheated, turn off the printer
and wait for half a minute then turn it back on. If the problem still remains,
contact a qualified service person.

– Try to run self-test
according to previous chapter to check if the printer itself works properly. If

1).
Check the connection of the interface cable at both the printer and
computer ends. Also make sure that this cable meets the specification
required for both the printer and the computer.
2).
Check the printer data communication settings against the computer.
The printer settings can be found easily on the self-test print out.
If the problem remains or the self-test fails, contact your dealer or a qualified
service person.
Poor printing quality
– Contaminants like paper scraps and dusts on the
thermal print head can lower the print quality drastically. Clean the print head
as described in previous section.
Paper Jam Problems
Paper is jammed inside the printer
– Push down the hood release button
then the top hood can be released. Remove the jammed paper and reinstall the
paper roll. Close the hood properly and firmly for operation.
If the auto cutter is also jammed, the top hood will be locked. However, in
most of the situations the cutter will retract automatically when the hood
