Printhead
The thermal printhead can become dirty from normal printer operation and keeping
the printhead clean will help insure trouble free operation. If print defects, such as
streaks or spots, do appear on print jobs, the printhead may need cleaning. To clean
the printhead, refer to Figure 4–1 and perform the following steps.
Turn the printer OFF before cleaning the printhead.
1.
Open the side access cover.
2.
Unlatch the printhead by rotating the printhead latch counter-clockwise.
3.
Remove the ribbon if installed (see page 3–9).
4.
Lower the hinge plate.
The printhead surface may be hot! Allow it to cool for 2 to 3 minutes
before cleaning. Do not touch the printhead with your fingers or
lubricant of any kind.
5.
Using a cotton swab dipped in 70% Isopropyl alcohol, clean the printhead by
rubbing the cotton swab left and right along the printhead elements.
6.
Raise the hinge plate and engage the printhead latch by rotating it clockwise.
7.
Close the side access cover.
