Question about Canon PIXMA MP760 All-In-One InkJet Printer

Pixma MP780 Series All-in-0ne Printer

Hello. Found your site while looking for solution for my printer problem. The display is stuck on "Please Wait", has been all day.

I've unplugged waited replugged; uninstalled reinstalled , checked computer configurationconfigurations. I thought that maybe it makes you wait if it needs new ink cartridges, which I have, but the ink arm won't slide to the middle so you can't put the cartridges in. Pressing the power on and off doesn't clear the Please Wait message, nor does anything else I've tried.

I have used the printer in the past without any problems. But then a few months ago it started to print a pale green color, no black print at all. I put in generic matched ink cartridges with no change. I ran the diagnostics, cleaning, maintenance, and still green. I then bought Canon's brand of ink, and was prepared to try these, but am stuck on Please Wait. Any ideas? Thanks for your time.

I have a Canon Pixma says it's offline and the printer screen is flashing 'please wait'. I've tried turning the printer and computer off and on, I've tried re-installing the printer but still...

Unplugging the printer from power and letting it sit for at least 10 minutes should clear the error, unless there is something physically wrong with the printer.

You get that message when the printhead goes bad. It's not the ink cartridges. You need a new printhead

My PIXMA MP780 is still flashing check the printer then press ok - an error msge ##357 keeps coming up. what does this mean pls?

This is an error in the position of the paper feed unit.
First, make sure there is no paper jam anywhere in the machine.. look inside, rear, where the paper tray (output) is, etc to see if you find any shreds or torn paper that may have gotten stuck and you didn't see.Look carefully in the zone of Purge unit, using flashlight in the right side on printer.Look in the sheet feeder too. If this not help your printer need service.

Not knowing where you are from, I can only give the following help.

Do a Google search using the following text:

Note the "+driver" (no space between the "+" and the word "driver").
