Checks and Adjustments
9.
Ensure there is a small gap between the printhead and the back
tension blade. Determine this by gently pushing the printhead
towards the drum — do not apply heavy pressure; push gently. The
printhead should move slightly before contacting the back tension
blade. If the printhead does not move because there is no gap, then
repeat this procedure beginning at Step 1. Verify the gap for the
center, left, and right edges of the printhead.
10.
Slide the tailpiece slide ramp all the way to its right; the printhead will
move away from the drum. Slide the printhead back to its
home-position.
11.
Make a test print on a sheet of the thin test media (2.7 mils thick)
included with a replacement printhead. The tailpiece slide ramp
should move about a 0.25 inch (6 mm) to the left when the printhead
passes in front of the media and sets the head-to-media spacing. If the
slide ramp does not move then the printhead-to-media gap is too
large, repeat this procedure.
12.
Install the tailpiece cover by hooking it on the top of the tailpiece and
hinging it down to snap in place on the bottom of the tailpiece. Be
careful to clear the torsion spring on the tailpiece.
Proceed to the drum alignment adjustment.
