I had enough of the C62, so I ended up dismantling the head assembly
yet again, as before I noted ink weeping from edge of the head clamp,
cleaning the whole face with isopropanol, re-assembling and a couple
of nozzles cleans brought it back to life along with the same old
symptoms.
So I removed the head assembley again knowingly for the last time,
upon removing the head clamp I was aghast with the amount of dried
ink that had caked up on one side of the clamp, the dried ink came
off in tiny clumps, I could see a small damp area where I presume the
ink had been coming from, the other three edges was intact with no
signs of ink build up.
Since this is the 2nd printer with the same print faults as the
original I am pretty sure that the cause was the same and a pretty
good bet that it was on the same edge.
It seems hard to imagine two printers with presummeably the same
defects, the nozzle selector board which is at right angles to the
print head, was intact and clean, no ink stains (this is a small PCB
that carries the connections to the print head), any corrosion of the
copper tracks will cause print problems and ink stains will cause the
copper tracks to short or become leaky to electrical signals that
drive the head.
What could have caused this in two printers I can only put down to
poor design or faulty manufacture of the print head. I doubt that
there is anything that I could have done to create this fault on two
printers in about the same period of time.
But as I have said it all began by a nozzle clean which seem to become
more frequent.
I put the printer where it best belongs - in the trash bin
