Missing Nozzles Compensation (MNC) Procedure This Missing Nozzles Compensation procedure (MNC) should be performed in case of a bad printing quality or after replacing the print heads. The reason for a bad quality could be clogged nozzles, nozzles firing aside (shifting), or not stable nozzles. These problems create quality problems such as micro banding. The MNC allows to eliminate these nozzles and compensate with others while printing. Limitation of this method is that not more than 5 nozzles per print head may be compensated. For example, the print head shown in Figure 4-10 has 7 missing nozzles. If you choose to replace such print head, refer to the Print Head Failure Approval Process in your Warranty Policy.

Missing Nozzles Compensation (MNC) Procedure
This Missing Nozzles Compensation procedure (MNC) should be
performed in case of a bad printing quality or after replacing the
print heads.
The reason for a bad quality could be clogged nozzles, nozzles
firing aside (shifting), or not stable nozzles. These problems create
quality problems such as micro banding. The MNC allows to
eliminate these nozzles and compensate with others while printing.
Limitation of this method is that
not more than 5 nozzles
per print
head may be compensated. For example, the print head shown in
Figure 4-10
has 7 missing nozzles.
If you choose to replace such print head, refer to the Print Head
Failure Approval Process in your Warranty Policy.
