I apologize for not responding yesterday, I was tied up on a support call that took the majority of my day.
I have attached the photos you sent (in order from top to bottom: A, B, C and nozzle check).
Your nozzle check shows all colors in the correct positions, and I can see the VLM is lighter than the VM, and LC is lighter than the C (I thought one of those carts may have been mis-filled, which would have caused the color shift you’re experiencing).
What I am noticing from the printed examples you sent, is the recent prints are significantly darker/more saturated, which is showing as a strong purple cast in many areas.
Was this nozzle check printed with the ConeColor inks, or after you reinstalled Epson and made several prints? If the nozzle check was made after switching inks, it would be helpful if you could check all the ConeColor inks by doing a Q-tip swab test comparing inks in the carts to inks in the bottles- using the bottle samples as the “known good” base, in case there’s any chance a cart was accidentally mis-filled. Use a clean Q-tip for each ink smear on a piece of scrap paper, and label each to specify the color and if it’s from cart or bottle.
Have you recently updated anything such as the printer firmware, computer OS, print driver, or software?
Have you shut down both the computer and printer at the same time for a total reset, then checked the output again? I have occasionally experienced sudden strange output that was solved by shutting down + restarting both machines.
Please send me screen captures of all your print settings for review, so I can review your complete workflow (not doubting you- but it’s an important thing to check and rule out, as one off setting can certainly effect the output quality/color).
I will await your responses to help me gain a better idea of your situation, in order to determine the cause and solution of this issue to get you back to happily printing.
Best regards~ Dana
Hi Dana, I spoke with our work study students and one topped off carts after I did in May. It’s looking like that may be the problem. I hope so any way. He’s feeling pretty bad … I assured him that while he may have made a mistake, no one can screw up like I can. On to your questions …
Yesterday’s nozzle check was made with Epson inks and after several prints.
I did the swab tests and I’ll attach the results. It sure looks to me that the VLM from the cart is too dark.
I’m also including an attachment of a ConeColor nozzle check comparison. The one on top was printed quite some time ago and the one on the bottom a couple of days ago. Again the VM looks dark.
We have not updated printer firmware, computer OS, print driver, or software.
We have shut everything down, unplugged the 4900 etc.
I still have the Epson carts in and the Blue skies are still Purple. If VM ink was added to the LVM refillable cart could the hose and printhead be still contaminated? Can I fix this? Will we ever have blue skies again?
I’m still not able to attach files … see what I mean about being the best at screwing up. If they don’t go through I’ll email them again and ask for a tutorial.
