Step Calibration
The printer step calibration is performed to verify and correct media feeding. The printer prints a complete
image pass by pass. A pass is the horizontal carriage sweep perpendicular to the media movement. After
each pass the printer moves the media forward for the next pass. This movement of media is called a step.
The distance by which the media is moved is called the step size and it has to be accurate. Step size errors
cause horizontal white or dark bands to appear in the print output. Step size needs to be adjusted for
multiple factors like thickness and roughness of the print media etc. Step calibration should be used to
fine adjust the step size and has to be done for each desired pass.
The
Step Calibration
and its parameters are shown in the image below:
Fig 52: The Step Calibration Parameters
First, feed the Base Step Value as 95000 (this is the approximate value and this need to be corrected by
following the below steps).
Follow these steps to perform step calibration:
Step 1:
Select the desired pass from the list and click on the
Select Pass
drop down list button (Refer to
Fig 52).
Step 2:
Feed the correction value in the
Revise
field (the correction value up to two decimal places) (Refer
to Fig 52).
Step 3:
Click on the
=>
icon (Refer to Fig 52) on the Step Calibration window. The correction value result
will be reflected in the
Step
field (Refer to Fig 52). The same step value will also be displayed in the
Steps
field on the
Quick Access Toolbar
