SECTION 3 – COMPONENT REPAIR
PRINTHEAD CRADLE ASSEMBLY
CRADLE LATCH LEVER
Note: Earlier models of the Sharp SX
are
equipped with latch pins in the place of cam
followers. If the latch pins need replacing, the latch
mechanism needs to be upgraded to the cam
followers. This procedure is best completed at
Sharp Packaging Systems’ facility by our service
personnel because substantial machine
disassembly is required.
The cradle latch lever holds the cradle into position,
compressing the pinch roller onto the film feed
roller to ensure the bag film is fed through the
machine. This works in tandem with the cradle
latch, located on the opposite side of the cradle.
Sharp Packaging Systems Inc. recommends
replacing the cradle latch lever and the cradle latch
together for best results.
1. If the cradle latch is worn, the film may track to
either side of the roller, or the cradle may
unexpectedly open or open easily. Also, it will
not “snap” into position when the cradle is to be
locked closed. If this is the case, the cradle
latch lever needs replacement.
The cradle latch lever is adjustment free.
1. Release the cradle latch to expose the
printhead and drive rollers. Remove the cradle
latch by loosening the two countersunk screws
from the bottom (Figure 3-272). Slide the latch
from the machine, being sure to catch the
nylon washer on the shaft between the latch
and side plate.
2. Once the cradle latch lever is free of the
machine, remove the two handles by
unthreading the two screws shown (Figure 3-
273).
TESTING
Always remove electrical power from the
SX
prior to performing any maintenance
on the machine.
