imageCLASS MF656Cdw - constant jam message, but no jam

giustonewport — Sun, 23 Mar 2025 19:00:16 GMT

Hello,

We are dealing with a printer that will print about 3 menus, front and back, before getting an error message that it is jammed. There is no jam. Sometimes it only prints 1 before it gives that warning. We called and asked support, who told us our paper was too heavy, so we ordered the one they recommend, the Neenah 8.5 x 11, 1952.m weight, 67 base weight. It is now giving us the same issues. We do not have this issue when we print on legal paper back and front, just letter size paper. Could someone please help?

I really can't tell what weight your paper is. Have you adjusted the paper weight to match your paper in the printer remote UI settings or the LCD panel? I've had the 656cdw since September, never had a jam. I use 24lb paper and adjusted the settings to Paper 3.

Greetings,

I don't recall the maximum paper weight the 656 is capable of, but the OP did use paper that was too heavy and jammed his 656. Its possible that something was damaged when one or more jams were removed. Tugging on heavy paper can cause alignment issues. I can't say what happened in this case definitely. I'd start by removing the paper drawer and re-checking the paper guides. I would also carefully remove and reseat the toners. Then retest.

The printer has a 3 yr warranty. If unsuccessful, I would contact support.

Thank you. We called them and they said the paper we were using before was too heavy, and this was the paper they told us to get

however, it is doing it as well. I think calling support will be our only chance, and may be a problem with the printer.

Well, you may have done damage to the printer by using, jamming and then having to extract the paper that was too heavy. That's why there's an owner's manual.

It's never actually jammed, it's only said it has. Thanks.

So when do you get the error? When you load the paper? When you send a print job? Does the printer do anything/make any noise before it displays the error?

When I put the paper in and begin printing. It prints three, and then says there is a jam. There is none. It looks like it begins to pick up the paper, because the one on the top is slightly forward than the rest of the paper in the drawer.

Sounds like a defect. I think you're stuck with Canon warranty support, unless you still have time to return the unit.
