5. 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
Temperature 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.
6. Once the locating tabs have cleared, pull the cover horizontally away from
the machine.
NOTE
Failure to assemble the rear EMO switch correctly results in the EMO
circuit remaining active preventing the machine from being powered up.
Upper Side Panels To remove the upper side panels, carry out the following:
1. Remove the rear printhead fixed cover (as detailed previously).
2. Open the front printhead cover.
