Duplex Rotational Adjustment 
This adjustment sets both the Duplex Home and Duplex Print Return offsets. 
These parameters control the rotational position of the flipper as the card enters 
or leaves the duplex module. This adjustment is best made with two instances of 
the Diagnostics software (start Diagnostics and then start another copy). 
Adjustment Procedure 
1.  From Diagnostics, select Printer and then Step Test. 
2.  Click on the Move duplex to home position button. The flipper will rotate 
and re-register at the home position. 
3.  Open a second instance of Diagnostics and go to the Printer Values window. 
4.  Examine the physical position of the duplex calibration pointer. The proper 
location of the pointer is at the letter "E" on the duplex chassis. 
•  If the pointer is right of the "E", add the number of units to the current 
setting (each letter represents 2 units because every other letter is shown). 
•  If the pointer is left of the "E", subtract the number of units from the 
current setting. 
5.  Verify the setting by re-homing the duplex in Diagnostics. 
 
6.  Set the other parameters based on the new Home offset. The table below 
shows what should be added or subtracted from the Home offset’s value. For 
example, the Handoff offset should be 77 units larger than the Home offset. 
Parameter Change Sample 
Duplex Home Offset  Baseline  17 
Duplex Print Return Offset  Add 6  23 
Duplex Handoff Offset  Add 77  94 
7.  Save the values to Power-on defaults.
