Hello,

My Canon s750 has been giving me trouble. It stopped printing black,
but my black tank is about 1/2 full. I figured it was a clogged head,
and I've tried multiple deep cleaning cycles, soaking in alcohol, and I
just tried a cleaning kit from inkjetsaver.com.

None of those things helped, and while I was running the last cleaning I
began to smell burning from the printer. I pulled out the head and it
was very hot, bit there was no smoke.

Does anyone have any suggestions on reviving it? Did I just burn out
the head on the last cleaning?

Thanks.

Ink passing through the nozzles also helps maintain an acceptable head temp
while in operation. IF you were to do many cleanings in a row with a clogged
head, I suppose it could get hot and smell, but I wonder if something was
not damaged in the alcohol bath.
In either case, I dare say it is history.

Considering the cost of diagnostics and a new head if that is the problem,
my recommendation (if in the U.S. anyway) is call Canon and take advantage
of the Loyalty Program. I picked up my iP4000 for just over $130 shipped
next day to my door. A new printer, better resolution and a new warranty.
That is if you want to stick with Canon any way.

I originally went with the Canon because of the separate head and ink
tanks, but now I've found out that actually getting a new head isn't
really worth it.

I'm now thinking that the HP model of replacing the heads with the
cartridge is the way to go. I guess you can always buy a refill kit and
get a little more life out of those carts?

Any advice on a multifunction device? Faxing from home would be nice.

Actually for a company it's the wrong way to go. Having separate tanks and
head is the only way to differentiate products without creating logistical
nightmare of having to sell hundreds of cartridges. There are two parameters
you want to differentiate, and both of them have to be done by having
different head:
- speed (head with more nozzles)
- quality (head with smaller droplets, or with more colors)

HP home printers are very limited in parameter range, and this is because of
using the same set of cartridges. They don't differ in printing speed too
much (are slower than canons especially in color), and are obsolete - they
still use 4 pl droplets. I guess when you sell so many pritheads they have
to be cheap :-(

Even HP knows it's better to have separate head and tanks and separate tanks
for each color. But it keeps this superior design for more expansive
printers.

"Choose HP's most cost-effective color printer for
general office use. Save money initially and over time,
with a low purchase price and four individual
high-capacity replacement ink cartridges that reduce
intervention and deliver consistent, outstanding print
quality and lowest cost-per-page. Each of the four ink
cartridges holds a single color, so when a cartridge
runs out, replace only that color, eliminating waste.
Four separate, long-lasting printheads are another
important element of the economical design-you don't
throw away a functional printhead when replacing an
empty cartridge."

But it's not as easy as in case of Canon, where you just pop 3-rd party
cartridge instead of original, for 1/5 the price. In Hp you either toy with
syringes, smear your hands with ink, deal with ink flowing out of the
cartrigde, and have a problem with resetting printer settings - as hp
printers have protections against refillers built in. Or you buy refilled
cartridge, which is unfortunately expansive - costs 1/2 of original
cartridge price.

I wouldn't count on on HP reliability too much. I used them in the past and
had a lot of problems with paper tray - in all models. Like taking multiple
sheets at once. Over time paper trays started working worse, at the end it
only accepted 1 sheet of paper at once. I guess it's kind of an planned
obsolescence on HP's part, as even Lexmark printers have very good and
reliable paper handling mechanism.

Thanks for your great insight into this.

OK, so this leaves me in this position:
I have a canon s750 with a burnt out print head. I haven't been able to
find a new print head for sale anywhere, but I hear they are expensive.
All of the logic behind the separate print head makes sense, and it's
the reason I went with Canon in the first place. However, given the
extreme cost for fixing it, I'm not sure it's worth it.

So this brings up the question: Did my print head fail abnormally? I
had been using cheap replacement ink carts, and only print a few pages a
month. If I had bought better quality ink, would the head not have failed?

I'm stuck here now trying to figure out if I should buy a new printer
(I'm intrigued by the multifunction devices), or keep spending money
trying to fix the one I have.

Well, generally you would not need to replace the head. I have several
Canon's (one almost 6 years old) and have never had a printhead fail. Yes it
can happen just like with any other brand, but with my Canon I know if it
does (on the 3 newer units I have) that the printhead is also covered under
the warranty. Even with the cost of the Extended warranty from Canon which
covered the head for the additional 2 years and using Canon OEM inks, I
still save plenty having individual tanks compared to my previous printers
with the all-in-one tanks.

Well you can get a new S750 printhead direct from Canon Sales or a local
Canon ASF, or even here
http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WD1V
for about $60. Now while it is VERY likely the problem you experience is due
to a failed printhead, you have to keep in mind it may be something else.
With the cost of a new Canon iP3000 being just $39 more than the printhead
and considering it will provide not only a new head, but also printer with
added features (higher resolution, auto-duplexer, dual paper paths, etc) and
a fresh warranty, IMHO I would probably opt for the new printer. That is of
course unless you know someone that has a printer that uses the same head
and confirm your S750 is a bad PH and want to save $39.

Not true, PartsNow and others also carry them.

I suppose you simply can't expect reliablility from an inkjet printer
nowadays. They are not build to last. Some time before, when inkjets were
more expansive quality seemed to be higher, now it's all shoddy. From my
experience quality starts with office-class laser printers that have 500
sheet paper tray and 30+ pages per minute speeds. This kind of hardware is
build solidly and works without problems even on high load.

I wouldn't count on HP to provide reliable inkjet. All HP inkjets I dealt
with had some problems with paper handling mechanism - jamming, pulling
multiple sheets or no sheet at all, pulling paper at an angle instead of
straight etc. All these problems had been hardly visible at first, then they
started getting worse with time. On the other hand they were all printing
very well looking text, and their heads rarely clogged even when left for a
few weeks of non-use. I wouldn't recommend HP for graphics printing mainly
because of too high cost of color ikjet cartridges.

I have both HP and Cannon. HP45a black cartridges for my 970 are about $26
each, refill spec say 40 ml ink.
Cannon BCI-6 Black are $11 each for 13 ml ink.
Work it out yourself!!
