So you've got 110# Index = 199 g/m2. The specs for your machine are maximum 43# Bond = 161 g/m2 from the cassette or 58# Bond = 218 g/ms from the multi-purpose tray. (Canon U.S.A. : Consumer & Home Office : Color imageCLASS MF8350Cdn)
So you cannot feed this stock from the cassette. The main problem is that heavier paper has difficulty making the hard vertical turn from the cassette.
And you can feed this stock from the multipurpose tray. The operators manual states that you may load only one sheet of heavy paper stock of 129 to 218 g/m2 media in the MP tray (probably because this machine uses pad separation in the MP tray, and cannot separate heavier stock. And the Heavy3 setting must be selected for the MP tray, and in the driver. http://gdlp01.c-wss.com/gds/0/030000..._en-us_R_1.pdf
The machines that are designed to handle heavier paper do several things that your machine cannot.
1) they increase the transfer current to accomplish proper transfer through the heaver media.
2) they increase the fuser temperature. Additional heat is required to fuse heavier paper stock.
3) they decrease the copy speed to increase the the amount of fusing time.
4) they have pickup roller/feed roller/separation roller feed systems to separate heavier paper stock.
5) they are able to duplex heavier stock so that smudging is avoided, when reloading the paper.
Now the harm question. Will it harm your machine? That depends:
1) You'll have more paper jams. There is always additional risk of fuser claw damage to the upper or lower fuser roller when you have jams. If you're one of those users that gets agitated and starts slamming around the machine when you get a jam, you'll also have user damage.
2) If the paper exceeds machine specs you'll have incomplete transfer and incomplete fusing. To you that means diminishing image quality, additional transfer waste collection, and toner buildup on fuser rollers and guides. That translates to streaks from the transfer belt and/or streaks from the toner on the fuser rollers, on the prints and copies.
3) You'll be replacing the multipurpose tray rollers more frequently. How much more frequently? That will depend upon what percentage of your paper volume will be heavy paper stock.
How long do you suppose that will take to print your job one page at a time?
And if you try to duplex it by replacing the once-printed pages in the MP tray, the pad separation will smear the first image. That is why this is not a suitable machine for printing heavy stock.
