Refer to Figure 4-18. The media guides are part of the print mechanism assembly. If they
are broken, the entire print mechanism assembly must be replaced. If the media guides are
simply bent out of shape, perform the procedure listed below.
1. Turn the printer Off (2). Disconnect the battery charger.
2. Slide the battery compartment door open and remove the battery.
3. Open the media access door and remove any media.
4. Stand the printer on a flat surface with the front of the printer facing you.
5. Refer to Figure 4-10 on page 4-18. Remove the printhead assembly by first lifting
the printhead off the platen roller. Gently bend in on one of the printhead pivot arms.
Carefully pull the printhead assembly out of the print mechanism module far enough
to gain access to the cabling.
6. Refer to Figure 4-11 on page 4-18. Loosen, but do not remove, the screw securing
the ground wire. Remove the ground wire.
7. Carefully disconnect the head-open switch wire from the spade lug on the printhead.
8. Refer to Figure 4-12 on page 4-20. Carefully disconnect the 16-pin connector from
the printhead.
9. (PT40x only) Refer to Figure 4-11 on page 4-18. Carefully disconnect the 4-pin
connector from the ribbon sensor board.
10. Using needle-nose pliers, carefully bend the media guides so the vertical portions
are perpendicular to the platen roller and the horizontal portions are parallel to the
roller.
11. Replace the printhead assembly into the print mechanism module by reversing
steps 5 through 9. Ensure the 16-pin connector on the printhead, 4-pin connector on
the ribbon sensor board (PT400 only), ground wire, and head-open switch wire are
connected to the printhead before operating. Ensure all connections are fully seated.
12. Close and latch the print mechanism module media access door.
