Based on the above figure, the list of mechanical checks appears and as per these checks, Print Heads need
to be adjusted with the help of tools provided. The list of mechanical checks are given as below:
•
Angle Check
•
Vertical Check

Let’s discuss each test and their result one by one in the upcoming section.
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 it’s parameters are shown in the image belo

First, feed the Base Step Value as 62000 for Roll to Roll and 116485 for Flatbed (this is the approximate value
and this need to be corrected by following the below steps).
