How to Operate the Arizona T220UV 55
Five Adjacent Nozzles Not Firing
The next example (see figure 11 on page 55 ) illustrates 5 adjacent black nozzles not firing at all. This introduces banding in
an image. It is caused by dry ink or other contaminants in or around the nozzle. This is fixed by cleaning the head with a swab
and UV Flush, then performing a High Purge on the individual color. If necessary, follow this by swabbing the affected head
and finally by syringing the affected head until the ‘curtain’ of UV Flush exiting the head is continuous – no gaps or spray
in the wrong direction.
