Perform only when the unit is OFF
with power disconnected and COOL.

switch.
2. Remove the protective backplate at the
rear of the unit. This piece should be
handled by two maintenance personnel.
WARNING
This safety interlock switch
is only to be defeated
temporarily while performing
this procedure.
Never operate the unit
unless all safety systems are
working correctly.
Serious Injury Could Result.
3. The unit will not operate while a safety
interlock switch is open. As a temporary
measure during this work, defeat the pro-
tective backplate interlock switch by taping
down the switch inside the right endframe.
4. Release tension on the return ribbons. Se-
cure the return ribbon guide assembly in a
high position by tying o from above with
wire or string or guide tape (Figure 7-23).
5. Place a tarp, plastic drop cloth, heavy
paper, or another temporary protective
covering on the oor at the rear of the unit.
6. Pull the return ribbons around their tracks
until all the lacing clips are accessible and
aligned at the back of the unit.
7. Remove the ribbon connecting pins.
Remove the ribbons from the idler rolls
on top and let the ribbons hang from the
guide assembly onto the protective oor
covering.
8. Place a tarp, plastic drop cloth, heavy
paper, or another temporary protective
covering over the return ribbons and guide
assembly.
CAUTION
Avoid gouging or leaving any
at spots on the cylinder.
The unit will work properly
only if the ne polished
surface of the cylinder
is preserved.
Clean the cylinder using
vertical motions, not a
sideways motion, to preserve
the ne polished surface of
the cylinder.
9. Clean the exposed part of the ironing cyl-
inder. Use a belt sander with 220 to 350
grit sandpaper. Use only light movements
of the sander, not heavy pressure.
Figure 7-23: Use wire, string or guide tape to
secure the return ribbon guide
assembly in a high position.
