My hp laserjet 3050 printer does not want to print,says no paper pickup

SOURCE: HP Laserjet 3050 No paper pickup

NOTE:
If the printer DOES NOT PICKUP paper .
That is a jam also so the places to look are smoth rollers or smoth spots on the rollers.
trays not adjusted properly and if they have it some trays have a coustom/standarsd switch (should be in standard for letter/legal paper

SOURCE: HP laserjet 3050 prints skewed vertically

250-sheet input tray (tray 1)
The input tray holds up to 250 pages of 80 g/m2 or 20 lb paper or fewer pages of heavier media
(25 mm (0.9 inch) or less stack height). Load media with the top forward and the side to be printed
facing down. To prevent jams and skewing, always adjust the side and rear media guides.
NOTE When you add new media, make sure that you remove all of the media from the input
tray and straighten the stack of new media. This helps to prevent multiple sheets of media
from feeding into the all-in-one, which can cause jams.

Hope this helps if not you may have a registration roller problem.
