Two days ago I completed the professional cleaning of my Epson 7900 using the intranet instructions here with PiezoFlush:
Now when I run a nozzle check absolutely no ink is printing on the paper. I’m assuming there is some adjustment I must have missed but I could use some direction. Thank you.
Most likely you have a dead or dying cleaning assembly that is simply unable to suck ink out of your head but instead is pushing air into the head plate.
The damper and cleaning assemblies need to be changed every 2 years (together). Sometimes the air pressure pump does too. A quick search of this forum and others will bring up relevant info.
best,
Walker
