Chapter 3 Hatches and Doors
The left-hand cover gives access to:
• The electronics incl. CPU board, mains connection, power
supply, Centronics interface pcb, and any optional interface pcb.
• The motors, belts and pulleys of the paper feed, ribbon feed and
the optional rewind unit.
The left-hand cover plate is fitted to the printer’s frame by means
of a total of eight #T10 Torx screws; four along the lower edge and
another four along the top.
CAUTION!
The electronic compartment contains wires and com-
ponents with dangerous voltage (up to 380V). Make
sure that the printer is turned off and the power cord
is disconnected, before the left-hand cover is re-
moved.
After having disconnected the power cord, open the right-hand
door. Using a #T10 Torx screwdriver, remove the four screws along
the lower edge first, then remove the four upper screws. Put the
cover plate aside on a soft cloth or similar material to avoid
scratches.
When replacing the left-hand cover, press it forcefully inwards to
overcome the pressure of the leaf springs. These are used to connect
the cover plate to chassis ground in order to create a isolated box to
prevent radio interference. Before finally tightening the screws,
check that the cover is aligned with the front moulding and the rear
plate and that it does not interfere with the right-hand door.
