Canon i560. It's reporting that my magenta is out of ink. It warns me that
the printer could be damaged if it's run on the ink out condition. How can
the printer get damaged for running out of ink? By the way, I printed
anyhow and low and behold, there's still magenta even though it says that
it's 'out'. What actually could happen to damage the printer? Can I keep
printing anyway or do as Canon suggests?

No, no, no... STOP PRINTING IMMEDIATELY!

Sad but true, the only thing that cools the nozzle resistors in the
printhead is the ink itself. When it's gone, you risk frying the nozzle
resistors I believe. Now unless you want to go out and buy another
printhead, around $55 on eBay, I'd suggest you change or refill the
cartridge - whatever you're preference.

See steve's review of the canon i850 to give you some idea how the ink
sensor works.
http://www.steves-digicams.com/2002_...anon_i850.html

Basicly when the reservoir is empty you get a warning that your ink is
low. Low = 20% left IIRC. There is an additional warning after this
that your ink is out. I've never seen this warning as I tend to
refill before then. But at the point that the ink is reported as being
out there should be a small percent of ink left. could be 10%, could
be 5%, I don't know.

Printing totally without ink on a thermal printer like yours can result
in, in theory, a number of things including burning out the ink jet
heaters. I've never done this my self, and i've known a great many
people who print till dry than add more ink. What ever the case, it's
time to get more ink unless your sensor is kapaut. If you pull the
magenta and see the reservoir still has ink in it, you know the printer
is on crack.

I already knew the resourviour is out because I checked a long time ago. I
knew it would just be time before I got the ink out warning. I was just
making sure that this was not just something to get me to change my ink to
give Canon more money. I already have the cartridge and will install it.

The cartridge has been replaced.

CHANGE THE CART FOR A CANON OEM CART. DO NOT REFILL WITH SOMETHING THAT
YOU BOUGHT FORM A RELABLER THAT DOES NOT DISCLOSE WHAT YU ARE GETTING

INK IS OUT BUT THE CART IS NOT DRY. THIS IS A GRACE PERIOD. IF YOU LET
IT GET BONE DRY THE PRINT HEAD WILL BURN AND WHOOPSE DOOPSE GET OUT YOUR
WALLET.

While I don't know the exact amount of ink left in the tank when you
get the ink out warning... it's under 20%. So we are talking less than
$2.40 of ink if 20%, $1.20 if 10% and 60c if 5% there and abouts.
Printhead as Taliesyn is $55 from various sources. If you normaly
would waste 10% (A guess) and push your printer to the limit, and need
a new head after the 10th complete set of cartridges you broke even. I
know people who do this, print till bone dry, but it's not a good idea.
Odds are you're giving Canon less money by replacing a cart near the
"i'm empty" warning.

I refill with bulk ink when I get the "low" warning so I have no
accurate meter.
