2.

Using the manual card transport knob, drive a 
card under the head and leave it there. With the 
card under the head - make sure it’s there - turn 
the adjustment screw to elevate the left end of the 
head bracket to the point where your CR-80 feeler 
gauge just slides under the bracket. Test the 
mechanical setup by running the card back to the 
hopper, then slowly out again. There should be a 
barely perceptible upward movement of the 
bracket as it rides up over the tapered pick edge of 
the truck, see diagram on preceding page. 

3.

Load a few cards with magnetic stripe. 

4.

Click Mag Position Adjust. The printer will then: 

a.

Pick a card from the hopper 

b.

Mag encode it 

c.

Back up, then run it under the read/write head 
again to determine the position at which the 
mag encoding begins 

d.

Eject the card through the laminator. The 
starting position is stored in firmware and is 
used for all subsequent mag operations 

5.

Click Mag Amplitude Adjust. The printer will 
then: 

e.

Pick a card from the hopper

f.

Mag encode it

g.

Back up, then run it under the read/write head 
again to measure average maximum 
amplitudes of the recorded data displayed on 
the Mag Data Monitor below 

h.

Pause for a few seconds to allow adjustment 

i.

Back up again, and repeat the read cycle 
continuously until the PRINT button is 
pressed, after which the card is ejected 
through the laminator 

6.

Turn the adjusting screw first clockwise then 
counterclockwise in quarter-turn increments 
while observing the data monitor. With the 
bracket setup described in Step 2 above, it is pos-
sible that there will little change in amplitude 
even with a full turn or two of the screw in either 
direction. 

•

If there is no appreciable change, press the 
PRINT button to end the test, then restore the 
default setup of Step 2 using the CR-80 card 
shim. 

•

•If the amplitude varies as you turn the screw, 
tune for maximum values. 

All three tracks should read at least 130. If there are 
track-to-track differences greater than 10, the head 
may be defective, or skewed in the bracket. If skewing 
is the problem, loosen the lock nuts on the clamp 
screws (diagram, preceding page), back out the screws 
a turn or two, then carefully free the head (which may 
have a light adhesive film on the surfaces mating with 
the bracket). Position the head with its rim a hair 
below the edges of the bracket, then retighten the 
clamp screws and lock nuts. 

7.

Complete the procedure by re-running Mag Posi-
tion Adjust as in Step 4 above.
