Mechanical Checks
Accurate mechanical alignment is the key for achieving good print quality. In case of misalignment, the Print
Heads have to be adjusted manually using the provided tools and alignment should be re-verified iteratively
until the Print Heads are perfectly aligned.
Angle Check
This test checks the mounting angle of all the Print Heads. Print Heads should be mounted at exactly 90
degrees to the carriage scan direction. In the figure below, when the Print Heads are mounted correctly at
90 degrees, then an unbroken vertical straight line pattern is formed, as shown below:
Fig 61: The Good Quality Angle Test
When there is angular error in a head’s placement, t
he line formed by a particular Print Head will appear
broken, as shown in the image below:

Let’s discus the next vertical check.
