I have a very stubborn head clog on the cyan color, that is not responding
to attempts to unclog it. When I print a nozzle check pattern, the top part
of every other row is not printing. Underneath the grids that are printed out
in each color are blocks labeled A through H. The "B" block looks like a comb
with its teeth up, while the "E" block below it is fairly solid, both of those are
cyan ink only.
I am wondering what the significance of each of those blocks are,
as well as what I should try next to get the problem resolved.
In case it was a bad electrical contact, I applied some Caig Labs
contact conditioner to the contacts on the printhead. I have tried
filling an ink tank with window cleaner and letting it soak for a few days,
and also using a syringe and tubing connected to the intake port on the cyan
color and hot distilled water to clear out the ports, as well as running cleaning cycles.
I can scan and post the nozzle check printout if that would help.
Thanks in advance!
