After doing a decent amount of printing with PK photo black, I switched to MK matte black ink. I ran a nozzle check and had 2 consecutive gaps for MK. I printed about 10 pages of letter-sized prints and do not see any banding. Next, 2 gaps appeared in the vivid magenta. I ran a utility cleaning and waited 30 minutes and the nozzle check had the same 2 MK gaps, but the vivid magenta went from 2 to 4 gaps.
I’m going to print a couple of 17x22" prints soon so this printer will not be idle in the near future.
Considering that I am unable to detect banding, should I run another cleaning? Or is 2-4 gaps not going to make a visible difference? Or should I try to get rid of all the gaps before the problem gets worse? Maybe clean with piezoflush on paper towels under the heads as shown in the inkjetmall video?
