Faithful Mimaki Strikes again

So my Mimaki cjv30-130 (cmyk) had some problems with contaminated prints which ended up being a combination of small things...now fixed. However, now a new problem arises. Please see the attached photos. I noticed it in some prints that I normaly print with these colors...like a magenta/very light purplish bleed through in in blue colors and white discoloration in greens. The green sample here those white streaks in the middle are not a reflection, that is the print. The blue sample is hard to see the purplish hue but its there right in the middle pretty much. Any ideas? Dampers perhaps?

Wow fast reply! All are under 3 months old and I clean every single day. This literally just started two days ago. Same color, same prints and all of a sudden it appears. Oh, and nozzle check comes out literally perfect. But it should, the head is only 1.5 months old.

 

Oh yeah I suppose, alot of business's shut down! I'm fortunate enough to be working my day job yet. But that may change any day now. I can pop the cover and take a look at them but I'll be honest I don't really know how to troubleshoot the dampers. My black ink is getting pretty low, estimate says 10% left. Maybe that is letting air in? The media is curling a bit upwards on each end while you look down at it... It's a fresh roll of orajet 3561RA... But I'm going to pop in a roll of wrap vinyl and do a test print and some more solid color squares of the problem colors. I'll post the pics shortly!

 

I went ahead and switched out the media and did the same exact squares as the first set on the previous media and they came out essentially perfect...I'm thinking solventinkjet is on to something with the buckling. I'm going to slag off about 6 feet of the other new roll and put a tail on it for the takeup reel and see if that helps. I'll report back tomorrow!
