A:AnswerI have been running this card stock pictured below without any problems. I also included two photos of what the online resource says is acceptable paper types.
A:AnswerI don't use it but just figured it out. First, of course, extend the paper tray completely out until it clicks by pushing the blue tab on the right and pulling back, to accommodate the legal size paper. Then with the flat side up and the long straight side towards you, just lay the dust cover in place. It can be done with the paper tray pulled out or pushed in. The two round pegs on the bottom side of the dust cover fit into two holes in the front cover of the paper tray where you grab with your hand to pull it out. Took me a while to figure it out as well. In fact, I didn't even know what it was for. Once you get it the first time, it is quite easy. I agree, no instructions or diagram for this is unacceptable. Seems you are expected to figure everything out on your own or go online and download a manual, or look for answers on a forum like this. I included two picture of the cover in place and one just to show where the two round pegs go. Hope this helps.
A:AnswerI looked this up and it said do not use coated photo paper that is made for inkjet printers. The heated drum could possible melt it and mess everything up. I have some Gloss brochure and flyer paper for inkjet/laser that is safe and works, however it is not nearly up to the look of photo paper. I was told at Office Depot that they could order me photo paper for a laser printer. I haven't yet. I am not sure that the print quality is up to the standards of a photo printer, but i have not tried it yet on actual laser photo paper. The sales tag had a check mark next to photos, so I assumed it would be good for photos. So far for me it's not acceptable, but like I said before, I haven't actually gotten any laser photo paper to try it on yet.
A:AnswerCanon MF644 will print on paper weighing up to 200 g/m2. That equates to 75 lb card stock.
Most common card stock is allegedly 80 lb or 216 g/m2.
Have not tried printing on paper over 200 g/m2, so I don't know if that's the absolute top limit.
75 lb card stock is described as postcard thickness, so if that will work for you, that's your choice.
