Says it all.....hmmmm....sure about that?
Yes.

Unless you have an explanation how that piece of paper causes straight line ink dropouts with perfectly split bimodal hues in a single swath. We've seen this many times. This is classic electrical irreparable failure.

We are open to changing paradigms if the data is presented. This would be an exciting addition for members with similar issues to look for in the future if true.

Did you try another nozzle check to test your hypothesis that the scrap paper is the cause?

No.....still moving slow to check everything in detail and do some thorough cleaning of internal parts before re-assembling.

YES.....hope you are right......because feeding this monster with new printhead and complete set of cartridges is money down the drain...

Nozzles did also get a dose of chemicals...

Ink was low when I got it.....and now it is only 1 more Nozzle Check printout, but will let ink use gravity until new test tomorrow.

Cleaning the Pro 1 print head yourself is a waste of time, because the printer can do a far better job itself..

Ok....but I can do better than this ;)
