Open the printer door by pressing the door latch
inwards.
Place forefinger against the lower edge of the
mechanism mounting chassis and thumb against
the base of the door (see Figure 6).
Carefully press the door and chassis in vertically
opposite directions until the catch is released. Do
not pull the door and chassis apart without first
releasing the catch.
Swing the chassis back, leaving the door fully
open. This will expose the printer mechanism
and ink ribbon cartridge.
Press down on the end of the ink ribbon cartridge
marked 'PUSH' (see Figure 7) and carefully
remove the used cartridge.
Fit a replacement cartridge, ensuring that the
paper lies between the ribbon and the steel
printer platen.
Check that the ribbon cartridge spindle is
correctly seated over the printer ribbon drive
shaft, and snap the cartridge into place.
Ensure that the ribbon is taut and parallel to the
paper.
If necessary tighten the ribbon by turning the
faceted disc clockwise using fingernail (see
Figure 8).
If there is some paper protruding from the front of
the printer mechanism, ensure that it will pass
clearly through the guide channel and past the
tear bar before snapping the chassis shut against
the back of the door.
Turn the paper roll by hand so that any loose
turns are wound snugly against the roll.
Close the door and check that the paper flows
freely, using the paper feed button.
For paper and printer ribbon refills, contact the
Metron Inc. factory.
