I have a SX engine based printer, and had at one time, a CX based engine.
I have for years, printed on card stock with either engine, (that is how
I made business cards until I got a small photocopier that works better)

at any rate, you can generaly run 110 lb cardstock through the laser with
no problem.  YOU MUST MANUAL FEED it, however.  I am not sure about the
machanical adjustment you are looking for.  I would suggest contacting
HP and getting a copy of the service manual for the appropriate printer
engine.  They have both CX and SX manuals.  These are complete service
manuals, with all adjustments etc etc.  Monkeying around with the 
mechanical adjustments is tricky.

In either case (sx/cx) the key is to provide a straight paper path.
That is automatic on the CX, but on the SX engines, you have to open
a little door like tray, and fold it down.  The major jamming problem
comes with you attempt to negotiate the curl that puts the paper upside
down on top of the SX printers.  The only other thing to remember is that
your paper should be dry, and not damp.  If you live in a high humidity
area, it would be advisable to keep the cardstock in a garbage bag with
one of those moisture absorbing packets.  The cardstock is a tad on
the thick side for you to get a really good bond (that is why I use
a BD-3110 copier from toshiba.  It does DEEP BLACK FILLS, and the
toner STICKS.  The fusing roller temprature is not quite as high on
lasers, so the thickness of the stock makes a big diffrence.  There is
a way to increase the temprature (an adjustment) but if you get it to
hot, then you have problems the other way with lighter paper.
Don't even think about trying to run TEXTURED business card stock
or 90 lb/110 lb textured paper through the laser.  The paper will go
through fine, but if it is say a linen weave style paper, the toneer
WILL NOT BE FUSED down in the "valleys" of the texture.  

Hope this helps,
Cheers
