Just for clarification - the reason I gave the advice I did is because if the
printer is in warranty and the problem is related to the ADF and turns out to
be dirty optics you will probably be billed by the repairer,

NOT IN DA USA
a great pity since
the optics are simple to clean. If on the other hand, the problem is printer
related then it is probably going to require a qualified warranty/service
agent.

ONLY THE MFG HAVE THE QUALIFIED PEOPLE. THEY KNOW BEST WHAT THEY DESIGN
AND BUILD AND HAVE MORE EXPERIENCE WITH THEIR SPECIFIC MODELS.
Vertical strips on inkjet printers are almost never caused by a failed
printhead, they are usually caused either by ink
ESPECIALLY AFTERMARKET INK
on the rollers or if they only
happen during scan to print (photocopying) by drity optics.
Please do not let the resident troll put you off, there are plenty of people
here willing to provide real help.

Cleaning the optics is a user responsibility and not covered by warranty and is
almost definitely chargeable work anywhere in the world.
The majority of repairs to Canon, Epson, HP etcetera are done by qualified
certified service agents. There are very few printer companies who do their own
routine or warranty servicing, there are very sound commercial and service
quality reasons for this.
Good luck

I MEANT THE 780

Why would the 780 be better? It's sort of a coin toss between the 760
and the 780 whether you want the sheet feeder and modem or if you want
the color tilt screen and 35mm scanner. I think the mp780 might have
an xD slot as well but I can't remember, I know the 760 does not.

But oddly enough the mp760 tends to go for more money than the mp780
even though a sheet feeder it more complex than a simple backlight, not
to speak of the modem.

Thanks for the reply Burt. My answers.
When you say "replace the print head" did you mean to remove and replace the same print
head that came with the unit to see that it is securely and correctly in place?
Yes, per the Canon support tech. They also sent me a replacement print
head free of charge, which I installed following the instructions
included with the print head.
Did they ask you anything about your ink cartridges?
Yeap, the tech seemed to think there was not a problem with the ink
cartridges. These are the original cartridges that came with the
printer, ahem, not OEM :). I bought the printer new less than a month
ago. The tape has been removed and they did 'click' into place.
Did you run a nozzle check?
Several times. And deep cleaning several times.
The nozzle check will probably tell you where the problem lies.
When the nozzle check is ran, you can see the 3 colors shift to the
left only on the character print out section. This section is about 1
and 1/2 inches from the left margin. Regarding the strips printing in
b/w, I believe the printout I tested this on may be using the color
inks to generate the black. On the nozzle check the black section looks
fine compared to the color sections. Since it's under warranty I plan
on taking it in to be repaired. If anyone is interested I can post the
results here. Thanks.

Please do post what the problem was. Helpful to all who would have a
similar problem with this unit. Unfortunately I was so focused on the
printing function that I didn't think about the scanning optics as being a
problem! Thanks to Tony, who has infinitely more experience with all
printers, for delving into that issue. What I didn't ask was the nature of
the "stripes". Was it white stripes that would possibly be from lack of ink
flow, and were they in the direction of the printhead travel, or were they
stripes of ink applied to the paper, possibly from paper transport elements
picking up ink and transfering it to the paper or, as Tony mentioned,
problems with the optics or foreign material in the scanning system. I
have never used an all-in-one unit, but I can not see Tony's point when
considering what problems I have seen from scanners and fax machines and
"stripes" from the scanning area.

I think you were too focused on the aftermarket ink problem being exposed.

In the business of competing with the mfg.

Measekite - he was using the original carts that came with the unit. You
are too focused on declaring that every printer problem in the universe is
caused by non-OEM inks.

Most of the manufacturers, Canon included, use independant repair facilities
for their waranty repairs. Your continual efforts to slam Tony, one of the
most helpful people on this NG.

Glad too see that you have given up your efforts to write Reggae dialect
lyrics about the evils of aftermarket inks on the NG.

NO SLAM JUST FULL DISCLOSURE. SOMETHING YOU WANT TO SUPRESS. YOU
SHOULD LIVE IN A COMMUNIST COUNTRY. YOU DO NOT NEED TO BOTHER WILL FULL
DISCLOSURE THERE.

Full disclosure - interesting.
You mean the way you disclose your real name, your real qualifications and your
real experience?

Communist country - interesting.
That's where people don't get to voice their opinions unless they want to risk
being hounded by miserable no lifers!
Also where shouting is used by inadequate people to convey a pathetic semblance
of authority.
Are you sure you aren't spoofing from a communist country? Probably not, I
suspect you wouldn't have the first clue how to do that.

I have always fully disclosed my business interests but seek absolutely no
reward for contributing here.

Ah well, time to do some real work.

I have no idea what the DA business is, I am certainly not in it anyway! I am
also not in the ink business; I am in the printer business which by definition
includes ink (OEM and non OEM) as a small part. I have disclosed this many
times in this ng but have never disclosed the name of my company nor its
limited geographical location and never will. Therefore I stand to gain nothing
but feeling good by trying to help others. I am not ashamed to make a living by
working hard, providing an excellent service and by the way supporting printer
manufacturers in a variety of ways!
What do you gain by hurting others?
DO U LIVE IN ONE
No I live in one of the world's finest democracies, do you?
BULLSHIT - YOU GOOTA BE A POOR BUSINESSMAN

Don't judge me by your pathetic and inadequate standards!

End of a pointless OT thread as far as I'm concerned but I'm sure you won't be
able to resist a response??????

The problem was too much grease! Some grease got in the ink
cartridges...no, just kidding. Actually, there was grease on the
encoder strip which was causing the print head to slip as it moved
across the paper. Apparently the problem was there in the b/w not just
in the color, but more difficult to see. The bar that the print head
slides across requires grease, although the tech mentioned he uses some
type of oil, and that somehow got on the encoder strip.

Across the back of your MP760 printer and probably most cannon printers is a Narrow (about 1/4") clear tape like piece that has black vertical lines all across it. This is located just behind the print head. Make sure this tape is clean. The printer head reads the vertical lines to keep the printhead in alignment with things. I bought a MP560 on Ebay and it had this vertical problem and it had a smudge where the vertical lines were. Cleaned it and it worked perfect. Hope this helps.
