Printhead
Replacement
The thermal printhead is subject to wear both from the
paper or transfer ribbon fed past the heat-producing re-
sistors (dots) and from the rapid heating and cooling as
the dot pattern is formed. Thus, the printhead will re-
quire to be replaced after a certain amount of printing.
How often depends on application, print media and print-
ing conditions.
The printhead is easy to replace:
1
Open the printer's top cover by pressing the two cover
locks on either side and folding the cover upwards/
rearwards.
2
Pull the green carriage release lever, at the left side of
the print mechanism, forward and lift the print carriage
to open position.
3
In case of thermal transfer printing, remove front core
with the used-up ribbon and leave it in front of the
printer.
4
Turn off the printer.
5
Remove the single Phillips screw at the centre of the
printhead bracket.
6
Carefully manipulate the printhead out of the bracket
and disconnect the cable.
7
Fit the replacement printhead in reverse order.
