B&H Photo has the rebate deal for $120 for the Pro-100. Less than the price of a set of ink and it also includes $44 worth of paper as well. Deal valid through end of February.

Well, it happened again. The representative (Mary? Nancy?) this time said that the printer needs to be plugged directly into the wall outlet, not in an extension. If all my products required this, I would only be able to have the printer and one computer (no monitor) plugged in!
To be fair, it is sharing a heavy duty 3-prong extension cord with an HP laser printer, which has never so much as hiccupped in the 3 or 4 years since I've had it!
Anyway, she said to unplug the unit, press the power button 15 to 20 times, then let it sit for a minute. Then plug it in. That worked.
She said it would also work to have it unplugged overnight.
Best of luck!

My Pixma Pro-10 wouldn't power up no matter what I did. I followed your "press 10x; press and hold; plug back in" method and IT WORKED immediately. So bizarre. But it worked!
I had this problem as well, and called the technical support line at the number above. The tech support person said to do the following sequence below, which worked! She said it had to do with a power surge. I do have this plugged into the same outlet box as a laser printer but don't have much option here at work. She said to do the following:
1. Unplug the printer.
2. Briefly but firmly press the power button 10 times in a row.
3. Press and hold the power button for 10 seconds.
4. Plug in the printer. At this point I heard a "snap"/"pop."
5. Press the power button. You should be ok.
UPDATE: I had the problem again, and a new rep said to press it 15-20 times while unplugged. Also, she said to wait an entire minute before plugging it in. That worked! She said it should be plugged directly into the wall, not into a power strip or extension cord. I'm not sure I'm going to be able to pull that one off in my 1983-built office!

A number of months ago this worked for me repeatedly. Now, no more. I can't get an inkling of life out of this printer. If this many people are having this problem isn't it a defect???

I would not believe that this will solve the problem but I am schocked to see it really worked.
Yes, unplugging and pressing On button worked my printer and it is working now.
thank you so much. you saved my night from nightmares..

I had problem too - PIXMA PRO-100, several years old, lightly used to print, and the unit would not power up. However, all the recommended fixes about pushing the button repeatedly did not work. The Canon tech support recommendation solution was initially to replace the power cord but turned out that was not the problem, as the power supply tested fine for continuity. So in the end as the next step, they recommended buying a new printer.
However, and in reply to people like christojo58 whose printer would not power up either, I later found the power supply was a removable unit, and I was able to find a used power supply at eBay. When I replaced the power supply, the printer now powers on.
So instead of having to replace and put into the solid waste (trash) a hefty professional 43.2 lb (19.60 kg) printer that otherwise worked fine, I was able to replace a power supply.
Seemingly Canon needs to reconsider and sell or otherwise provide replacement power supplies for this printer, and maybe engineering figure out why the power supply is a weak link item that fails.
