frequency banding (less than an inch between lines) can be caused by other noise or
imperfections in the paper path.
Solution
1. Print a solid area fill plot (insert plot here) and measure spacing.
2. Reset belt tension and rerun diagnostic 1040 plot. Check pulleys and bearings for any
slop or run-out.
3. Clean rollers and other paper handling mechanisms, adjust belt tightness and ensure
that the motor is mounted securely. If tuning the system does not solve the problem,
drive components may need to be replaced.
PA05: Top of Form Transition Error (TOFTE)
PA05 displays as a set of horizontal lines visible near the top of the page.
Cause
TOFTE results from a change in paper speed as it transitions to the starwheel feeder
after the print zone. If the transition is not smooth, it will result in the horizontal lines.
The problem can be exacerbated by thick or curved media and can be improved by
reducing the starwheel force, staggering the starwheels and improving the dive angle of
the media as it enters the pinch. It could also be any problem with the starwheels
sticking, jamming or being out of position.
Solution
Ensure that all of the starwheels are spinning easily and that the spring force is
correct. Use thinner media, and ensure that the media is curved so that it transitions
smoothly into the star wheel pick area. For labels, use media that does not have the
ladder removed.
PA06: Bottom of Form Transition Error (BOFTE)
PA06 displays as a set of horizontal lines visible near the bottom of the page. This
occurs 20mm from the bottom of the page.
Cause
BOFTE results from a change in paper speed when the paper is released from the grit
shaft that precedes the print area. Differences in speed between the leading and trailing
paper handling drives can make the problem worse, as can improper tension settings on
the belts and pinch wheels. The paper thickness and shape also plays a role.
Solution
Ensure that all belts are properly tensioned. SEE TOFTE
