IQ7 Deletions RAP

Initial Actions
Reload with fresh, dry paper of the correct specifications. Paper contaminants (such as fibers
or other particles) may cause spot deletions by interfering with the second transfer. If the prob-
lem occurs with heavyweight paper, ensure that the correct selections are being made on the
print driver and/or UI. If the problem is not resolved, continue with this RAP.
NOTE: Small white deletions with a sharp edge are usually caused by Fuser offsetting. Go to
the IQ16 Spots RAP.
