QTR-Quadtone RIP

Hi Greg,

If you have inks in all the slots, try running an auto head check on a piece
of plain paper.
This is a much better indicator of nozzle status.

Also the first/last inch of paper/film is prone to banding as the paper is
held by only one set of rollers rather than 2.

Also the cartridges may need shaking if the printer has been sitting for
some time.
Best to do this when you next need to change one. Take out and shake them
all.
They have a little ball bearing inside that you can hear rattle around. -
though this is nothing to do with your banding issue.

Mike
