Canon Bubblejet Problems
Canon BubbleJet printers not printing after cleaning
(From: Handy (handy@redshift.com).)
Take out the cartridge that you want cleaned. Find
that hole that ink comes out of, squeeze the
cartridge until ink comes out of that hole -
actually drips. Put it back in the machine, clean it
at least FOUR times. Usually on the fourth time for
some reason, it works. Just clean the one that you
think needs cleaning.
Canon BJC 600 problems
(From: Rob Connelly (connelly@ix.netcom.com).)
I have found that sometimes the BJC 600 series gets
confused and needs to be reinitialized. If you
haven't already done so, unplug it from the wall,
wait 60 seconds for the internal supply capacitors
to completely discharge, then plug it back in and
try again. When you remove it from the AC line it
goes through a complete warm up cycle and resets
itself.
Also, the contacts that mate with the print head are
notorious for oxidizing. You might want to carefully
clean them (lightly) with a pencil eraser and some
isopropyl.
If these remedies don't work, the Canon 1-800 number
will put you in touch with their tech department,
and they are really quite good at determining what
the problem is over the phone.

When I was working on printers, we'd see a few of
the 600s in with corrosion on the ribbon cable end
under the printhead. NewKote apparently had a
venting problem with their copykat ink cartridges,
where in some situations ink would spurt (leak?
drip?) and somehow corrode the ribbon cable.
I never tried to replace one and see if it could
actually be repaired with just the cable, but I did
try vigorously cleaning the cable end: no conclusive
repair.
BJC 600 print head error - lights flashing
"Upon powering up the printer the two lights flash
indicating a print head error. However by cleaning
the electrical contacts (with alcohol) on both the
print head and the printer the printer works
temporarily. Within a day or two the problem
resurfaces. When the printer does print it prints
excellent quality. The nozzles seem to be is good
working order."
(From: Al Savage (asavage@iname.com).)
Although printhead failures are common on the 600
series, so is failure of the ribbon cable to the
printhead. This is an acknowledged problem from
Canon, when aftermarket ink reservoirs are used
(i.e. Pirana or NewKote). Somehow the ink gets up to
the cable/printhead interface and corrodes it. When
I was working on them (about 18 months ago) Canon
and NewKote were pointing fingers at each other. It
appeared to be a reservoir venting problem.
