Front Panel The front panel is secured by a ring head quarter-turn fastener and a button
head quarter-turn fastener.
1. To remove the front panel of the printer, open the front printhead cover and
locate the two quarter-turn fasteners on the inside of the panel.
2. After releasing the fasteners, tilt the top of the panel away from the printer
and lift clear of the guide pins that locate the panel to the printer frame.
Rear Panel Removal of the rear panel requires a 4mm Allen key to release the two button
head quarter-turn fasteners located externally at the top corners of the panel.
After releasing the fasteners, push downwards on the panel to clear the rear
printhead cover, tilt the top of the panel away from the printer and lift clear of the
guide pins that locate the panel to the printer frame.
Safety Covers Safety covers are fitted to the side panels to protect personnel from inadvertent

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.
