Printhead Pressure And Support Adjustment - Datamax Prodigy Operator's Manual

3.7 Printhead Pressure and Support Adjustment

The Printers printhead pressure is not adjustable. Two springs in the
head mount assembly apply a fixed 9.5 lbs of force upon the printhead.
The adjustment of the Printhead Support may be required if you are
changing from wide full width media to narrow media that is
significantly different in terms of thickness.
The head support plate exists for the purpose of supporting the outer
end of the printhead when narrow media is used. Without this support,
the printhead would bear down on the drive roller, causing diminished
print quality and premature wear. The head support plate needs to be
engaged only when the media width is less than 4 inches.
To make the adjustment, loosen the two mount screws that fasten the
head support plate, leaving the screw on the left snug (see Figure 3-9).
Using the media to be printed on, cut a strip about 5 inches long. Place
the strip between the drive roller and the printhead, and then engage the
printhead by rotating the head lift lever to the down position. Then
push down on the head support plate on the right hand side until it
comes in contact with the roller bearing plate just below it. Finally,
tighten the two mount screws to secure the support plate.
