Printer problems … fixed.

After cleaning print head and deep cleaning print heads and still not getting a decent print out, I came across this site PrinterKnowledge, started by Rob Ludlow’s nifty-stuff.com, which helped understand the nature of the problem.  (Anatomy of a Canon print head helped a lot – see photo below.)

It was the print head, but it needed more careful attention.  And it was clogged, but asking the printer to clean the print head didn’t resolve the problem because it can not actually dissolve the clogged ink in the print head.  Fortunately there was some solvent left on the shelf from JetTec.  Patiently cleaning the head with solvent, q-tips and paper towels for half and hour, then letting it dry did the job.  (By the way, if necessary you might need to inject solvent through the print head or soak overnight, but you decide!)

Checkout PrinterKnowledge if you’re having trouble.  It could save you time and money.
