56 T220UV User Guide
The previous example (see figure 12 on page 55 ) shows that the black head is poorly positioned in the inner carriage. The
head is overlapping with its neighbor on the left and there is a gap between it and the head on the right. Also there appears
to be a delay before the head fires relative to its neighboring heads, which would indicate that the head is not pushed down
fully in its mounting hole.
There are also 2 nozzles out. As they are not next to each other this should not introduce an artifact in the image and they
will probably recover on their own either during the image or during the pre/post print automated maintenance. If the nozzles
do not recover then further maintenance will be required (see below).
[13] Poorly Operating Magenta Head
[13] Poorly Operating Magenta Head
The final figure shows an example of a magenta head that is operating poorly. There are nozzles out and nozzles with poor
directionality causing overspray. There will definitely be banding visible in any parts of the image where magenta is used.
A dirty head, ink pooling on the nozzle plate, or ink curing around the nozzles, can cause this banding.
A High Purge on the individual color may fix this - if not, try a Recovery Purge. If necessary follow this by swabbing the
affected head.
If left untreated the overspray from this head may cause similar problems with other heads nearby.
