Points to
note:
1. The
stop
pin
(integr
al with
the rear
flipper
arm) rests on the bottom edge of the carrier,
alternating from one side to the other in
consecutive flip cycles
2. Azimuth adjust rotates the entire assembly to
bring the flipper arms parallel to the carriage - a
very sensitive adjustment
3. The arms must move freely, without end float.
Over tightening of the screws will lock the arms.
Card held by flip arms : As the carriage moves
into the flip station, the card slides into grooves in the
flip arms. The entire flip assembly is then elevated
clear of the platen.

The flip
station
requires no
routine
maintenance
other than
occasional
vacuuming
out of debris.
Typically, there should be no need to alter the factory
settings.
If the flip station ceases to function, or functions
erratically, the technician should perform the
following tests before replacing components.
1. Power OFF. Remove all cards from the hopper, then
close the hopper cover. Disable the main cover
interlock so that the printer will function with the
cover open. Power ON.
2. On the host computer follow this sequence:
Start > Printers (or Printers and Faxes) > Right
click Zebra P640i > Properties > Device Settings
> Control >
Advanced Utilites
3. Click Move Truck to Flip Station.
4. With the flip arms horizontal, click Flip Test 3 (No
Flip) a few times, noting what happens as the
carrier begins to elevate at the start of the flip
cycle.
This is a test for clearance between flip arms and
platen. If the arms touch the platen, even lightly, there
will be tendency for one or both of them to rotate a
little as the carrier rises. The arms
must be parallel to
the platen, with a few thousandths of an inch clearance
each side. Using a flashlight, check the gap by
inserting a 0.004" (0.01 mm) feeler gauge between
each arm and the platen. (A narrow strip of regular
copier paper can be used instead, but a long metal
feeler gauge is better.)
Caution • Cards thicker than 0.033"
(0.84 mm) may jam in the flipper arms.
