The print unit is a self-contained module and attached to the print-
er's center section by means of four #T20 Torx screws. There are
also a number of cables running from the print mechanism to the
CPU board (see Chapter 15.3), which are not illustrated.
The ribbon rewind unit is driven by a belt from the motor of the
print unit via an idle pulley attached to the inside of the center sec-
tion. The liner drive roller (fi tted underneath the platen roller) may
be driven by a belt to the optional liner/batch takeup stepper motor,
if a liner/batch takeup kit is fi tted. These belts have to be removed
before the print unit can be pulled out.
