Service Test Print 5 - Transparency/manual feed
mode. This print allows you to evaluate
transparency printing as well as manual feeding. It
prints two prints, one with primary color fills and one
with secondary color fills and a band of 50% blue as
this is a popular background for overhead foils.
Look for: Look for uniformity of fill with no
scratching. Evaluate the print on an overhead
projector. Some print artifacts visible on the print do
not show when projected. Likewise, some defects
do not show until projected.
Causes: The ink drops from the jets are traveling in
incorrect trajectories. The printhead is incorrectly
mounted or its printhead-to-drum spacing is
incorrect.
