This looks like the infamous clogged damper problem. Try inserting a cart of Piezoflush into the black position. Use the QTR calibration program flush/print the black onto some cheap photo paper. Continue printing black tests until the black comes out pink. Allow the Piezoflush to sit in the black line and heads for a few days (printing standard test patterns and doing head cleanings during that time, are OK). After a few days, when no more black shows in the printhead test, reinsert the black ink cart, and use the QTR to prime the line, just as before. Hopefully, this should cure the problem.
[QUOTE=lmbruns;11939]I am using an Epson Stylus Pro R3000. I am printing using Lightroom running under Windows 10.
I develop a large number black streaks or smudges on the left side of print. See attached. They are mostly horizontal about 1/2 inches long and about 1/16 inch wide. There are some vertical streaks which very in length. They are rather consistent.
I did the following to try to clean and clear out the problem:
- I used PiezoFlush to clean the capping station, print heads and wiper blade - twice
- I did nozzle cleanings through the printer driver and I included an attachment of the nozzle check
= the nozzle cleaning sometimes delays the streaking for as much as one picture but usually less
- I tried setting the Platen Gap to wide and paper thickness to 11 mm but this had no impact
At this point I am stuck. Do I replace the capping station or the whole nozzle assembly?
Are there any less drastic measures?
Thanks for any help you can give me,
