Even if the liner takeup unit is intended to be factory-fi tted, it is quite easy
to upgrade a printer with such a device:
• Remove the cover plate from the center section using a #T20 Torx
screwdriver.
• Pull out the rear part of the timing belt from inside the media guide
assy.
• Fit the takeup pulley into the recess in the center section and wrap the
timing belt around it. When you pull the timing belt, it will engage the
pulley of the stepper motor.
• Screw the takeup shaft through the rewind pulley and into the center
section using a pair of pliers. Then screw the takeup guide shaft into
the center section. Use tape or similar to protect the shafts from being
scratched by the tool.
• While rotating it, press the takeup hub onto the shaft and the pulley.
Press until the snap-lock engages the groove in the shaft.
Replace a broken or worn-out timing belt like this:
• Remove the media guide assy. as described in Chapter 7.5, "Label Stop
Sensor/Replacing the Sensors."
• Pull out the rewind bobbin from the shaft. You will need two straight-
slot screwdrivers or a special tool to pry the two legs of the snap-lock out
of the groove in the shaft.
• Separate the pulley from the takeup hub while taking care so the spring
clutch stays inside the hub.
• Fit a new timing belt over the pulley of the stepper motor.
• Put back the takeup pulley and rewind hub as described in Chapter 8.3.
• Reassemble remaining parts in reverse order.
