I somehow found out that unplugging and replugging it would work.... except that recently it didn't.
I found this, and it suggested plugging the printer into the wall instead of a power strip.
This worked, which was a relief, but I'm left with two questions. Apparently, the failure to turn on unless you fiddle with it is a problem with a number of Canon printers. Can this possibly be a hard problem, considering that I've never had any other electrical device that suffers from it?
Is the electricity from the wall different from the electricity from a power strip? Should I give up on laws of nature? Or might it be that sometimes the printer needs to be unplugged and replugged a bunch of times, and having many alternative places to plug it in (I'd previously gotten good results by plugging it into different outlets on the power strip) means that I eventually achieve the magic number?
