IQ 12 Missing or Partial Image RAP
Use this RAP to troubleshoot wide deletions in the process direction that affect a complete
printhead or a when a single colour is missing from a single printhead.
The problem is usually caused by a communication or power error in the marking unit and
causes the substantial or complete loss of a single printhead,
Figure 1
and may be seen in one
or all colours. The problem may be an ink supply problem if only a part of the printhead is miss-
ing.
NOTE: Blank sheets accompanying multi-feeds or chase pages following a jam are normal.
Ensure
IQ 1
