Thank you very much
If I remember (because I am not at the Lab now) I had turn off the auto nozzle check,but after every 2-3 prints it is there again.
I can print only in service mode continuously . Can I do something to fix it ?
Is this a new printer or one that's older? What you describe was how the printers functioned originally ... auto nozzle check didn't really turn it off all the time. A firmware update in late 2009 changed it. Is it possible you need to do a firmware update? With ANC turned off, the only time the printer will ever perform a nozzle check and clean on it's own is when you do a PK/MK switch.
