P640i Card Printer User Guide

If you detect that either of the arms catches at one end 
of the platen, but is free at the other, the carrier needs 

, see below. Always correct for 

azimuth error before adjusting the gap between arms 
and platen. 

If there is no azimuth error, but insufficient clearance 
between arms and platen, see 

 below. 

Azimuth adjustment: The flip station carrier is 
held in alignment with the platen by a U-shape 
molding that rides along a fixed rail in the motor 
housing behind the carrier. Using a fiber tip pen mark 
the screw for reference, then adjust it in very small 
increments, such as 1/8 of a turn. A full turn of the 
screw moves the U-shape molding about 0.08" (2 
mm), rotating the carrier almost 3º. 

To fine tune the azimuth adjustment, run Flip Test 3 
with flip selected. If the gap between the rear flipper 
arm and the platen is to spec (0.004") at the arm’s 
mid-point, 

 if neither end of the arm snags after 

repeated flip cycles, you can be sure the azimuth 
adjustment is good. 

Flip carrier sensor tabs: This view is from left to 
right, along the center wall of the printer ockwise 
rotation of the azimuth adjust screw causes clockwise 
rotation of the carrier assembly, viewed from above. 
Example: if the platen tugs down the right hand end of 
front flipper arm as the carrier elevates, the carrier 
needs clockwise rotation. 

Gap adjustment: The flipper arms must be 
separated so that they clear the platen, but not so far 
that they 
lose their 
grip on 
the card. 
There is 
a fine 
line 
between 
too tight 
(grabbin
g the 
platen) 
and too 
loose 
(failing 
to hold 
the card 
securely)
. 

Because it is easily accessible, and doesn’t require 
removal of the rear cover, try to correct the problem 
with the front flipper adjustment. 

Mark the bushing for reference with a fiber tip pen. 
Using a ¼" open end wrench, adjust in 

, such as 1/8 of a turn. A full clockwise turn 

of the screw moves the bushing in by about 0.03” (¾ 
mm). 

If you are starting from scratch, set the nose of 
bushing about 0.02" (½ mm) proud of the inner 
surface of the carrier. You can estimate this by 
comparison with a CR-80 card, which is 0.03" thick. 

After adjusting the gap: Check operation of the 
flip station by running 

 with Flip, both with 

and without a card in the flipper arms.

The rear flipper arm is different: You need to 
remove the rear cover for access. Also, it’s not 
possible to adjust the bushing without first removing 
the cam.

Flip Test 1: Picks up a card, runs it to the flip 
station, flips it, raises it to the laminator infeed, then 
ejects it through the laminator. The sequence repeats 
until the PRINT button is pressed and released. 

Flip Test 2: Picks up a card, runs it to the flip 
station, flips it, returns it to the platen, then backs it 
out to the card sensor (by the mag head). The 
sequence repeats until the PRINT button is pressed 
and released. 

Flip Test 3: See Flip Station Adjustment 
Procedure, preceding page. Exercises the flip station 
by raising and lowering the flip station carrier, one 
cycle per click. The radio buttons select Flip or No 
Flip cycles. 

Eject Card: Picks up a card, runs it to the flip 
station, raises it to the laminator infeed, then ejects 
it through the laminator. Like Flip Test 1, but done 

once only, and without flipping. 

Flip/Pause: Picks up a card, runs it to the flip 
station, raises it to the laminator infeed, then holds this 
position (termed the Insertion Height  in the flip 
station dialog) until the user presses the PRINT button 
(at which point the flip carrier descends, and the truck 
returns the card to the hopper). 

Inserting a CR-80 card into the 

flipper arms to check for grip is easier if 
you remove the color ribbon.
