Uneven printing Possible causes of uneven

 Mechanical misalignment of
the print head
Have a technician:
 Check the platen for uneven wear.
 Verify that the print head shoulder screws
are secure before replacing the print
head.
The shoulder screws that secure the print
head should be properly centered in their
holes, allowing the print head slight
vertical movement.
Gaps in printing

may have a short or damaged
connectors
 Defective print head
 Faulty circuit board
 Defective paper
 Dirty print head
Have a technician:
 Check the print head and signal cables
for shorts, opens, or damaged connectors.
These cables plug in between the circuit
board and the thermal print head.
 Check the print head and circuit board
and replace as needed.
 Replace the paper, using a fresh pack of
properly stored paper.
 Clean the print head.
