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.

Step Calibration
result image is shown as below:

From the above figure, you get the accurate step adjust correction value. The correction value is either
positive or negative. If the value is positive, then add it in the current step adjust value for the Print
Head calibration. On the other hand, if the value is negative, then subtract the value from the current
step adjust value. From the above, you can conclude that the pattern is corrected at
“0”
position.
