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 drive belts of the print unit and ribbon
rewind unit.
• The headlift sensor.
• The brake of the ribbon unwind unit.
• Stepper motor and drive belts of the paper rewind unit.
• The CPU board.
• The Centronics interface board.
• The power supply unit.
• Optionally one extra interface board.
The CPU board is fitted inside the left-hand cover plate, which is
held by a total of 8 #T10 Torx screws: 4 along the lower edge and
another 4 under the top of the right-hand cover.
CAUTION!
Before removing the cover plate, make sure that the
printer is turned off and that the power cord is
disconnected. The power supply unit, that is fitted
behind the CPU board, contains high voltage wire
and circuits.
When fitting 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.
