Question about HP Officejet Pro K5400dtn Printer
The above suggestions are the easiest to do first, but I've found that all the mechanisms of the machine work except that the pick-up rollers won't drop down. This is a mechanical error in the cluster of gears that you can see when you open the top cover. If you look through the top left opening you can see the cluster of white gears that sit on a metal plate just below the top metal paper guide. Very carefully give the gears a little squirt of WD40 and move them around with your fingers as much as you can(very small opening and you may have to use a tool, be gentle). There is also a black and white coupling to the left and above these gears that you can push to the left a couple of times to insure that is not binding. Worked for me.

The HP officejets usually have problems with paper handling so here's a few things to check and try:
If none of these have any effect and the printer is in warranty you could try for a warranty replacement but if you're a bit more technically minded it's likely that the rubber pick up wheels/rollers are in need of some TLC in which case something like this may help:
Note: I've found that after cleaning the rollers can become too clean so a quick run round with your finger to add in some grease and dust (sounds insane but it works) can resolve the issue.
Hopefully you'll find the solution in there somewhere. Good luck :)
