Print-Quality Troubleshooting
Big Bands OHP
This print allows you to evaluate transparency printing. It prints two
transparencies from Tray
1, one with primary color fills and one with
secondary color fills and a band of 50% blue, as this is a popular background
color for overhead transparencies.
Look for: Scratching on the print. 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: Confirm that you are using the transparency that is supported for this
printer.
Clean or replace the paper release blade. For more information about scratches, see
“Scratches or Marks Parallel to the Long Axis of Printing, Particularly with Film” on
