I'm having trouble finding the max card stock size (thickness) for this printer, I thought it was 120lb but my printer is jamming with 100lb. I've gone to printer preferences and changed the paper to "thick", but it still jams. Can anyone please tell me if this printer is capable of printing 100lb car stock? and, if so, what do I have to do to get it to actually print? Thank You, Eric

Some Ideas / Checkpoints to consider
The problem might be the paper type.
For example, the printer supports Index paper (an ISO standard paper type) to 110lb / 200 gsm.
Other paper types, for example "Cover" paper, is heavier than Index paper -- 100llb Cover paper = 270 gsm.
One of the many references --
PaperPapers - Help Understanding Paper Weights
---------------------------------------------------
What else?
Check that the printer is aware of the Paper Size / Type.
- Use the Printer Control Panel right after changing the paper or after opening and closing the paper intake tray
OR
- Use the Embedded Web Server (EWS) to check / adjust Paper Size / Type.
See example below in section Message Content References
---------------------------------------------------
Printer is older - normal wear and tear might mean that a supported paper size, type, and weight that used to work might have problems later in the printer's service life.
---------------------------------------------------
Printer might be dirty - even supported paper sizes, types, weights might stick, balk, or jam in a dirty printer.

Sorry for the late reply, thank you for responding. I was able to follow the recommendations above and test, no problem using the IP address, but the paper still jams at the rear rollers. It's "standard" (I guess) 100lb paper I bought off of Amazon. The printer is at home and does not get excessively used.
This is the Amazon title: White Cardstock - For School Supplies, Kids Art & Crafts, Invitations, Business Card Printing | Extra Thick 100 lb Card Stock, 8.5 x 11 inch, Heavy Weight Hard Cover Stock (270 gsm) 50 Sheets Per Pack.
The brand is Fine Cardstock.
I would try another brand if the community thinks that will help, or is the 270 gsm the problem? Thanks in advance for any help

You are welcome - no worries about late replies.
Smiling.
The printer does not support 270 gsm card paper.
The printer does not actually support any "Card Stock".
No "extra thick" paper.
The printer supports
Index card paper weight - 110lb / 200 gsm.
Index is an ISO standard paper manufactured to certain weights, surface, and "whiteness".
HP defines this paper in their media specifications as "Card" paper or HP Card.
Regardless of the name, the paper is essentially Index paper.
Printer - in good condition plus clean and sparkling - supports "card" paper of this type (110lb / 200 gsm).
True -- Index weight "card" paper is wimpy paper for crafts, signs, or projects.
The brand is not the problem -- the paper is just too heavy for the printer.
You might get away with 225 gsm -- but you know, this is a guess and paper can get expensive.
Were it mine to do, I might try 220 or 225 gsm but I'd not expect it to work.
Sorry, no -- You cannot tell the printer you are using Photo paper unless you are loading / using photo paper.
Notes – Paper Types
Photo Paper might be supported to 250 gsm, or, if specified, to 280 or 300 gsm.
Supported photo paper types vary – Photo paper types, sizes, and weights are printer model dependent.
For example, HP Advanced Photo paper is 250 gsm.
Do not select Photo paper if you are actually using a different paper type.
Do not attempt to use 300 gsm photo paper in a printer that does not support paper in that weight class.
Index card paper is an ISO paper type.
On a printer that supports “card paper”, HP Card paper -- unless otherwise specified -- is defined as Card / Index paper and is generally supported to 200 gsm.
If “card” paper is not listed in the Specifications, paper in this weight class might NOT be supported.
HP Brochure and HP Professional paper are typically the same weight. Brochure paper comes in two print surfaces: Matte and Glossy. HP Brochure / Professional papers are 180 gsm in weight.
HP Presentation Paper is a lighter weight “brochure” type paper at 120 gsm.
If the “heavy” paper type is generally supported but is not listed in the job configuration Properties, select the closer alternative: For example, in Properties > select “Brochure” / “Professional”.
Plain Paper is typically defined as standard office paper at 16-24 lb in weight.
