REMEMBER TO USE ESD PRECAUTIONS
To remove the Print Head Assembly from the Printer Mechanism Assembly:
1. Rotate the Knife Stepper motor gear train until the Rotary Knife Blade is
parallel to the bottom of the Printer Mechanism Assembly (Home position).
2. Orient the Printer Mechanism Assembly so that the Print-head Assembly
faces you as shown in Figure 7-10 on page 12.
3. Push on the Print Head Assembly until the upper set of alignment pins escape
from the alignment slots in the Paper Path Assembly.
4. Push down on the Print Head Assembly, and then rock the Print Head
Assembly toward you.
You should now be able to easily remove the Print Head Assembly.
When removing the Print Head assembly, be careful not to lose the
small tension spring behind it.
When reinstalling, make certain that the Rotary Knife Blade is parallel
to the bottom of the Printer Mechanism Assembly (Home Position), or
you may do damage to the blade, or the printer may fail to restart
without running it through a power cycle.
