I feel like an idiot, but how do you insert a print cartridge inside an hp deskjet f340 all-in-one...?

with our breaking it? I have been trying for the last hour, doing what the directions said to do, I just can't get it in! Is there a trick to this?I feel like an idiot, but how do you insert a print cartridge inside an hp deskjet f340 all-in-one...?
Not normally, it slides right into place. Sometimes you can try too hard to do something. Leave it for a couple of hours and then try again. Also go to the Hewlitt Packard company website. They have step by step instructions on how to do everything with respect to all their printers, including replacing the cartridge. The instructions are both written and spoken, so make sure your sound is turned on. Don't worry, it will be okay.I feel like an idiot, but how do you insert a print cartridge inside an hp deskjet f340 all-in-one...?
Normally you just open the printer, take out the old one and slip the new one in on a slight angle.
