Latex 315 Color Shift

HP Latex 315 Print and Cut Solution Printer

#1 jkrier6599 9 months ago

A couple of months ago I started to notice that the printer was giving me color shifts in my gray scale that also made my blues look washed out. Replaced the Black/Cyan printheads and all went back to normal.

Fast forward to this week. The problem is back

I have recovered the printheads, done nozzle checks and see nothing outstanding. But the alignment check of the printhead has me puzzled.

Why is there a color shift on the big black bars. The one on top is the one I ran right after installing new printheads. The one on the bottom is from yesterday.

#1 looks like ur cyan firing is very weak, try weight ur ph, belive got air inside your ink tube. or maybe the Fi towel got problem.

Kelvin - "try weight ur ph". What do you mean?

Also what is the "Fi towel"?

Hello, We have a few suggestions:

  1. Did you do a printhead alignment and a color calibration?
  2. Remember that the color calibration has to be repeated for each media
  3. To be able to recover colors from day 0 you have to do a color calibration on day 0 to be able to compare.

I hope this information helps

Hi Sonia,

I did a printhead alignment and color calibration.

This color shift just happened out of the "blue"

HP has decided that both of my black heads are clogged. Sending out replacement heads. time will tell if this fixes the problem.

#8 The new C/K printheads showed up yesterday. Installed last night and problem is gone (again). Will see if I get more than a month out of these heads.
