First, I'm running Mac OS X.4. I bought the Canon Pixma iP4000 back in
April and have had a persistent problem with banding. Canon sent me a
replacement printer, and a replacment print head, to no avail. I've
tried printing from a different computer (another Mac), using different
software, different images, etc. Same result. I've talked to Canon
support about 6 times and they've basically given up.
Anyone else on a Mac (or otherwise) have this problem? It sure seems
odd that more people would be having this problem because I've done
nothing out of the ordinary, printing-wise. I'm using the stock inks
that came with the printer, on Canon Photo Paper Plus Glossy paper.
I really wish I'd taken this thing back to the store for a refund when
I had the chance.
Ugh.
TIA

Well... if you want to help isolate the problem, there are some service
mode button presses that will print the test patern independent of your
computer. I doubt that it's it but this would cover all bases.

With the printer power turned off, while pressing the Resume/Cancel
button, press and hold the Power button. (DO NOT release the buttons.
The LED lights in
green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button.
(DO NOT release the Power button.)
3) While holding the Power button, press the Resume/Cancel button 2
times, and then release both the Power and Resume/Cancel buttons. (Each
time the
Resume/Cancel button is pressed, the LED lights alternately in orange
and green, starting with orange.)
4) When the LED lights in green, press the Resume/Cancel button the
specified number of time(s) according to the function listed in the
table below. (Each time
the Resume/Cancel button is pressed, the LED lights alternately in
orange and green, starting with orange.)

Press resume then power to do a self test print
press resume twice then power to do an eprom info print
The following link till show you about what they look like.

If self test is OK and the output from the mac is screwed up, well you
have an oddball software problem.

If selftest is BAD and output from the PC is BAD, printer, inktanks,
or printhead is BAD and yell at Canon.

The printer is pretty good. I like them. They for the most part work
well. But they are based on a thermal printhead that is a close cousin
to a lightbulb. They do burn out. It's far more likely that you are
the victim of a bad production run of printheads than having an issue
because you are running a mac. This sucks... but the problem can be
resolved and canon is obligated to resolve the problem even if you feel
so disapointed your final solution is to sell the sucker on e-bay.
