Printer Mechanism Alignment

If head jams are occurring, the alignment of the printer mechanism may

need correction.

Open the printer top cover, then install a ribbon cartridge (see page 16)

and position the print head to the far left toward the green thumb wheel.

Observe the area between the print head and the printer cavity (circled in

the f ollowing illustration). If the ribbon cartridge touches the pivot frame

or press n ut, the printer mechanism needs realignment.

This illustration shows the print head to the far left in the printer.

1 Loosen the four screws that hold the mechanism in place using a Phil-

lips screwdriver (see the following illustration).

2 Realign by pushing the printer mechanism to the right, away from the

green thumb wheel.

3 Push on the right side of the printer mechanism to the back as far as it

will go.

Note: In this position, the right back edge of the printer mechanism may

touch the pivot frame. The left side must NOT touch the pivot frame.
