Feed Ribbon Tension Adjustment
Adjust the tension of the feed ribbons when
they sag or track to one side of the ironing section.
Both conditions cause excessive wear on the
ribbons and shorten their life.
Required Tools
Wrenches:
3/8”
9/16”
Perform only when the unit is OFF
with power disconnected and COOL.
1. Turn power OFF at the main disconnect
switch.
2. Open both endframe doors.
3. Locate the feed ribbons drive roll tension
adjustment bolts (Figure 7-2, A). There is
one on each side of the machine.
4. While holding each adjustment bolt in
place, loosen its locknut (Figure 7-2, B).
CAUTION
Do not over tension the
ribbons. Too much tension
can cause excessive motor
amperage and premature
ribbon wear.
5. Adjust each bolt the same number of turns
clockwise until the ribbons are snug. Test
the tension by pulling up lightly on the
ribbon. Resistance should be felt within
1/4” to 1/2” (6 to 13 mm).
6. Turn power ON at the main disconnect
switch.
7. Turn the SPEED knob to the slowest
speed.
8. Run the unit briey and make sure the rib-
bons track straight and do not rub on the
ribbon guides under the feed table.
9. If tension on the ribbons is uneven, ribbons
track toward the end of the drive roll where
the tension is highest.
10. Stop the unit and turn power OFF at the
main disconnect switch.
11. Either turn the adjusting bolt counter-
clockwise at the high tension end, or turn
the adjusting bolt clockwise at the low
tension end.
12. Repeat Steps 6 to 11 until the ribbons have
the correct tension and track evenly.
13. Stop the unit and turn power OFF at the
main disconnect switch.
14. While holding each adjustment bolt in
place, secure its locknut.
15. Close and secure both endframe doors.
WARNING
Never operate the unit unless
all safety covers are in place
and all safety equipment is
working correctly.
