It actually does the tearing sound when it exits. I might see if I can
get a cleaning assembly as I heard that be4 that that could be my issue.
They are like $200 isch I heard. I hope it's not the print head.
A service manual would be helpfull. If I took a picture of the magenta
lines that are causing problem is there a way to find out from that if
it's the printhead or the cleaning assembly. Some jets do actually work
just partial but some have like a weird pattern to the failure. It is
hard to describe but I'll take a picture tomorrow.
