I am getting very faint banding on my P2DN digital negatives. When printing a nozzle check pattern I can see that one tiny portion of the Yellow channel is missing. Every other channel shows no gaps in the nozzle check.
It was suggested that I might have introduced air into my print heads by performing an automatic nozzle check (that I was unaware that I should not perform with BW inks as it confuses the colour sensor) and was told to leave the printer settle down for 24hrs.
I have done this, so can safely say that the gap is not caused by air in the print head.
I have ran a head cleaning by the gap is not eliminated
Should I remove the cartridge and try to flush with piezoflush to dislodge the slight blockage or should I run more manual head cleanings? What is the most economical in terms of ink? By introducing piezoflush to the nozzle won't I be required to run 2 head cleans to purge the piezoflush and re-instate the ink?
Also, how often should I be cleaning the wiper blade and capping station of my printer to keep in optimum condition?
