13. Electronics Compartment
13.1 Introduction
The Electronics Compartment is off limits to the normal user, but
for the authorized service technician, it contains a number of parts
of great interest:
• The stepper motor and belts of the print unit and ribbon rewind
unit.
• The headlift sensor.
• The brake of the ribbon supply unit.
• Stepper motor and belts of the optional liner/batch takeup unit.
• The CPU board.
• The Centronics interface board.
• The power supply unit.
• Optionally one or two extra interface boards.
The CPU board is fi tted inside the left-hand cover plate, which is
held by a total of eight #T10 Torx screws; four along the lower
edge and another four under the top of the right-hand cover.
WARNING!
Before removing the cover plate, make sure that
the printer is switched off and that the power cord
is disconnected. The power supply unit, that is
fi tted behind the CPU board, contains high volt-
age wire and circuits.
When fi tting back the cover plate, press it forcefully inwards
against the conductive leaf springs before tightening the screws.
Check that the cover is properly aligned with the front and does
not interfere with the right-hand door.
