I just emailed Art for his cleaning manual.
I've had my 740 for maybe 5 years now. It's always worked great. The
nozzle-clean utility has always brought everything back to quality.
I print only every other month with this printer.
But now things are bad. I just ran out of color and replaced the cart
with a new one. It's an Amazon Imaging Value Pack. I think a previous
cart of theirs worked fine. It's at least a year old.
The nozzles just won't print a clean test pattern. Very striped.
I just took the carts out and swabbed around inside the head
compartment with Q-tips soaked in alcohol and Windex. They started out
very inky but in the end seemed fairly clean.
I cleaned the whole track area of the heads with a clean thin rag
wetted with alc/windex. Then I centered and unplugged the printer and
ran the heads over top of a wetted strip of rag. I scrubbed the heads
from the underside with a moderate shoe-shine motion. I did this til
the cloths all came out fairly clean.
I tested it---first test almost OK, next tests nothing. Plain paper. No
pattern would print. A half hour later I sometimes I get a 80% pattern,
other times almost 0%!
I hope I didn't destroy anything.
Whups, now I see it's telling me my black level is low. And my color
level is 3/4's---ha, after printing nothing but a few tests with a few
stripey marks on them.
Does tape over the cart chip work good for fooling these things?
Well, thanks! --JP
