Measurements are taken within the left and right printing areas of the platen.
Measure at 3 to 5 locations while rotating the PF roller. Be careful to prevent anything from altering
the accuracy of the measurements taken and to avoid any warped areas of the gum roller.

The standard gap should measure between 0.25 and 0.3mm (a range from 0.2 to 35mm can be
expected depending upon any variances).
