Canon i9100 banding problem, continued

[DL]

The story so far:

I'm having a problem where certain images printed with my Canon i9100 printer
have a find set of lines or bands. I've tried another printer and another print
head, provided by Canon, and the problem remains. We're now to the point where
I've provide the image in question to Canon for them to look at.

(The first time I sent the image, they replied to my email and said I must have
forgotten to attach the image. The funny thing was, their return email actually
contained the image I sent them. To help them out, I not only re-sent the image
but also posted it to a web page.)

As I haven't heard otherwise for a couple of days, I believe they're beyond the
"we don't have the image" phase and I'm waiting to hear back.

Another individual sent me private email saying Canon reproduced a banding
problem he was having but offered no solution other than sending a new printer
(which is likely to have the same problem.)

p.s. I'm still looking for additional volunteers to print a 4x6 copy of the
problem image on their i9100 printer on Photo Paper Plus Glossy. Send private
email to (e-mail address removed) and I'll send you a link to a ~1MB .jpg image.

For anyone who cares, it's been two weeks since I sent Canon an image that
demonstrates the banding problem. I have had no response. I sent a follow-up
email tonight.

I strongly suspect that there's an inherent defect in the Canon i9100
hardware/drivers/firmware that results in banding on certain images.

I've been working with Canon customer service on this issue. There was some
problem in that the discussion was focused on my camera or noise in the image,
rather than the printer. I finally sampled the color that was causing the
banding problem on my printer, provided a single color image to Canon for them
to test, and Canon then was able to reproduce the banding an a smooth even
colored image. Their position was that the banding was "in spec" because it
wasn't visible at a "normal viewing distance under normal lighting." I didn't
accept that as an answer (I could see the banding with my printer with normal
distances under normal light), and asked for this to be escalated up the chain.
Working with a customer relations person, I agreed to try the new model i9900
which they shipped me overnight. I found that the i9900 did substantially
better on one of my troublesome images, and also on an image another person had
shared with me. I kept the i9900 and returned the i9100.

Bottom line is, though it took quite a while, I'm satisfied with the outcome and
Canon's behavior in this matter.

If you're interested in more detail on this please email me.

Is it possible that your observation does fit to my request "stripes
on print-out by BJC-i560x"?

How does your "banding problem" look like in detail?
