PIXMA iP8720 won't print oversized (13x19) just threads paper

alidoucette — Sun, 08 Mar 2026 19:27:59 GMT

Hello! I'm hoping someone can help me figure out why my Pixma iP8720 won't print oversized. I can print letter size just fine, but as soon as I try to print oversized it just threads the paper, and blinks yellow on the error/thread button.

I'm printing from Lightroom Classic by adding a custom size of 13x19 (not available in the paper size presets). I've just replaced all of the toners with Canon toners so ink isn't low, and I'm using Canon Matte Photo paper. Just printed an 8.5x11 today so communication to printer is working fine.

Looking for any advice, thanks!

Update: it will also print borderless 11x17 (which is an available paper size in my page setup settings from Lightroom Classic). Just not 13x19 (not available as a preset size).

Did select Custom size in the printer driver?

Yep, I was choosing custom size, and inputting 13 x 19. I tried with a .25" margin and also borderless w/o a .25" margin.

I’m having the same issues. I know you posted this a year ago, but did you ever figure it out? It’s so frustrating. It will print smaller sizes just fine, but not 13”x19”

Ridiculous that Canon support doesn't have anything on this, when they happily advertise this printer as working with 13" x 19" paper.

As it turns out, an A3+ sheet, commonly referred to as 13x19, is actually 12.95"x19.02" (329x483mm). Setting up my custom paper size to those dimensions fixed the issue.

This is such crap!

Canon should have a profile for a page that it advertises the printer can use.

And when it does not, we should not have to rely on one another to access this information. Canon should be supporting this kind of information.

But I'm very happy that you figured it out, I was ready to toss the thing out a window.

Sorry this is such an old post I'm commenting on, but THANK YOU for the help!

I set my custom paper size to the A3+ sheet settings (12.95"x19.02") but the printer is still spitting out the paper. 😞

The only thing that I can think is that I might need to trim a teeny bit off the sides of the paper? (The 0.05"?) Did you do that?

Haha, this is ridiculous!! Thanks!

Try unchecking detect paper width setting.

Unchecking paper width setting should work with A3+ paper. If using Canon A3+ paper its actual dimensions are

32.9 cm by 48.3 cm, in inches it measures 12.95"x19.02".
