hello everyone
was called to this machine with half of the cyan not working, performed print head recovery and lost the entire cyan - performed many head cleans and got up to 90% working again, tried another recovery and lost the lot again
cleaned the print head with alcohol, replaced the ink recovery unit, fitted new cyan ink & even used the HP advanced cleaning page
has anyone, ever, anywhere seen a solid solution for what appears to be air in the cyan? lots of customer complaints in the HP forums but no solutions
please help
