Longevity of Canon inkjets?

How perceptive, I don't notice a problem with my i960, but YOU DO!

hehehe...good one!

Measekite has the innate ability to see things as they aren't and then
rearrange them to his liking. So in the end he's not even remotely close
to the actual facts anymore. Fact is, my 3 printers have now accumulated
over 5 years of printing using the same printheads and aftermarket inks -
without failing. They are lasting. One early one failed after a month.
It was a bum printhead (and printer!) and was replaced. Anyone can get a
lemon. But they are all lasting now and show no signs of failing any
time soon. But Measekite is definitely failing when it comes to telling
the truth.

I do not believe the kid. He just has to justify his poor decisions.

Actually if you take right care of your Canon printer I suspect the print
head will last a very long time. The key is to make sure the print head
is never starved of ink. If you keep an eye on the ink flow and make sure
the print head is never short of ink to print it will last a very long time.

It can be fatal to the print head if it does not get enough ink to print, as well
as to cool the heaters in the nozzles.

Correct viscosity of ink and proper capillarity of the sponge in the cartridge
are two main elements to provide proper ink flow to the print head.

The print head will be able to handle light load such as printing color text
and heavy load such as printing photos only if the ink flow is right.

It is an enormous joy when you see your printer being able to keep printing
and never give slight problem to bother you, especially when you use 3rd
party ink and ink cartridges.

Well put! Especially the part about not letting the print head get
starved for ink. During the first 30 months of use of my i950
printer, there were several clues that I failed to interpret at the
time. The most important, as I now consider it, is when the printer
starts "banding" there has to be an explanation.

That first printhead eventually failed after roughly 3000 full size
8x10 color photos, and I replaced the printhead many months ago and
started all over with new cartridges. Today, after having refilled
most of these cartridges 6 or more times, I spotted the first banding.
This time with lots of detective work (mostly just careful examination
of the variables) I recognized that one of the cartridges seemed to
have some small gel like particles in the reservoir. These apparently
were plugging the sponge, and if ignored would plug the nozzles. I
then examined the particular bottle of refill ink, and realized these
gel particles were precipitates or coagulants in that particular ink.


Then I followed the trail back, and realized that ink was past its
published expiration date. I promptly threw out the rest of that
batch, and opened a new batch of that same brand of refill ink, and
checked it. No particles visible. After taking a brand new empty
refillable cartridge and using that new ink, the banding has
disappeared and the photos are again pristine in quality. So,
hopefully, I caught it in time to avoid having to replace the
printhead again. (And I do have another brand new printhead if ever
needed.) Incidentally, this second printhead is well past 600 full
size 8x10 color photos and hopefully will make the 3000, as long as
I'm attentive to the details. After having worked a full career in
engineering and research in the chemical industry, I feel far more
qualified to comment along these lines than that illiterate jerk whose
all too frequent remarks sound much like Charlie McCarthy, the dummy
of Edgar Bergen. (Am I showing my antiquity here?)

I hope these points are useful to other refillers.

Never, ever trust anything that comes from meashershithead. He is the
model idiot of this ng.

I have been using a BJC-250 since 1998, and only the first ink
cartridges were Canon. It still works just fine.

Burt - you are absolutely correct, my apologies to Bergen and
McCarthy!!!

Did the termites finally get him?

I like his (Edgar's not Charlie's) daughter on "Boston Legal" better
than McCarthy's acting... I always found his performances a little
wooden ;-)

I studied ventriloquism as a youngster, and as ventriloquists go, Edgar
Bergen wasn't very good... his mouth moved all the time.

Art - initially it hardly mattered as his act was on a radio show.
Surprised that TV didn't kill the act. I think that it was so popular and
the Charlie McCarthy character was so endearing (unlike our wooden headed NG
dummy) that Bergen's skills didn't matter, even on TV.
