Rear Printhead
Fixed Cover
To remove the rear printhead fixed cover, carry out the following:
1. Remove the rear panel.
2. Release the two quarter-turn fasteners that secure the rear printhead cover
to the cover frame.
3. The rear printhead cover is interlocked with the upper printhead cover using
locating tabs. The rear printhead cover must be lifted to allow the locating
tabs to part.
NOTE
The knock out panel is removed when the printer is connected to a Temper-
ature Control Module (TCM). If a TCM is not fitted the knock out panel must
be intact, or this would contravene the safety requirements the printer is
tested to. Where the knock out panel has been removed and a TCM is not
fitted, ASM recommends fitting a new rear panel.
