Title: bad Cyan Nozzle Check on 9890 - please help
Post by: Paul Ozzello on April 29, 2016, 01:21:26 pm: Hi all,

I've had problems with the CYAN channel on my Epson 9890 since the day I bought it - the printer is two years old now and on it's 3rd head, and today I'm having problems again with CYAN...

I can print a perfect nozzle check after a power cleaning, in fact I can print a dozen perfect nozzle checks one after another but as soon as I make a print, I get CYAN banding and the nozzle checks are bad until I do another Power cleaning. Is this a problem with the head, air in the lines, a problem with the capping station ?

Thank you,

Paul

Perhaps cleaning or replacing the wiper, may also need to use some distilled water on thin micro fiber cloth to try and soften up/clean the ink from the head.

Thank you Wayne,

I tried as you suggested and let the cloth sit behind the head for a few hours before rubbing it gently back and forth - but it hasn't helped...

Yep - Epson Hot Press :) Do you think the paper fiber particles accumulate on the head ? But why is it always CYAN and never the other channels ??
