Hello Guys, I have had this persistent problem with the black head laying down a random pattern when printing. It is not all the time but occurs sporadically.
I have had a tech out twice... at first they thought it was the main board which they replaced... no difference so they refitted the original then cleaned and refitted all ribbon connectors... Viola! all sweet again until about a month later when it all started again.
This time I reseated them myself after cleaning with electronic cleaner but one of the strips subsequently shorted and took out the yellow/magenta head so I got the tech back to fit a new head and two new connector strips. All back to normal for another three weeks before it all starts over again.
I know that the humidity here in Queensland is a big problem but the aircon always runs when the printer is going. Still, the dampness permeates into everything I suppose.
The trouble is that I cannot put my finger on the exact location of the problem.
Any ideas??? There must be a wealth of experience out there...
