Paper Axis Calibration
The paper axis calibration procedure ensures that the processing that drives the
stepper motor is correct to minimize line length accuracy errors.
To perform the paper axis procedure:
1. Select “Utility Menu” from the Main Menu. This brings up the Utility Menu
as shown in Figure 3-19.
2. From the Utility Menu, select “Calibration Menu”. This brings up the
Calibration Menu as shown in Figure 3-25.
3. From the Calibration Menu, select “Use Paper Calib.” Ensure that Use
Paper Calib is set to ON and press “Ok.” This allows the printer to store
the data that is entered in step 7.
4. From the Calibration Menu, select “Paper Axis Test”. This runs the paper
axis test which prints out two “T” figures that are mirrored from each other
and about 33” (83.82 cm) apart. See Figure 3-27.
