CP80 and CP80 Plus Service Manual 5-53
Upper Duplex Rotational Adjustment
This adjustment sets the Upper Duplex Home offset. The Duplex Print Return
and Duplex Handoff offsets are adjusted based on the resulting value of the
Duplex Home offset.
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.
