Figure 27 shows that the black head is poorly position 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.
Figure 27 Black Head Poorly Positioned
Figure 28 shows 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, too much heat causing ink to dry around
the nozzles, can cause this banding.
A High Purge on the individual color fixes this. If necessary follow this by swabbing the
affected head and finally by syringing the affected head until the ‘curtain’ of solvent
exiting the head is continuous – no gaps or spray in the wrong direction.
