Ok, I just went down to CPS Central and rummaged through a bunch of crap to dig up the 1500 nozzle cap that I removed. It is in one piece, with no signs of glue except a little on the left and right sides. It looks like I chipped away a thin bit of the left side about 2 inches long and then it pried right off. The switcher is intact and a separate piece. BTW this version of 1500 had a screw under the nozzle cap, screwside.
I'm pretty sure that your 1700 cap is glued and that simple prying is not enough.
