Turn the printer onto its right side so you can access its underside. Check the gap where the input tray was. Remove any loose paper or other obstructions in the gap. If any paper is jammed inside the gap, grasp the paper with both hands, and then pull the paper slowly but firmly toward you to remove it.
HP Printer Paper Tray Lock A Paper tray lock is used to prevent the tray from accidental use. The lock is used in printers that contain multiple trays. It is mainly used in printers while inserting special papers into the input tray.
With dot matrix printers, paper is often feed through pins on a wheel that grab and slowly move paper through the printer. With inkjet and other page printers, paper is fed through the printer with rollers that grab and move the paper through the printer.
Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer. False paper jams can also occur.
Paper that is loaded incorrectly in the input tray might prevent the tray from closing completely. Remove any paper from the input tray, and then reload the paper correctly before closing the input tray. Grasp the handle on the input tray, and then pull the tray toward you to open it.
Paper Overloading

Because many desktop inkjet printers are top-loading, it can be easy to overload the tray.

Tray 2 lift error can be caused by a damaged, dislodged cartridge contact in the body of the printer, which would explain why multiple cartridges do not solve the problem. Open the cartridge door, remove the cartridge and inspect the contacts on the left side, they should look the same as the picture below.
The flag located right of the pick-up roller has a fixed position. If the flag becomes stuck or broken, it will produce a 60.02 tray lift error or a “LOAD PAPER” message.
To remove the icon from the taskbar: Open HP Support Assistant, select “Updates and tune-ups.” Then click “Other settings” on the bottom left and uncheck the taskbar options in the “How would you like to be notified?” section. I hope this helps.

Load tray errors when the tray is full are usually the result of a mismatch between the size/type of paper requested by the PC, and the size/type of paper present or set on the printer.
The paper tray is empty or overloaded. The paper is curled. The print side, or shiny side, of the paper is not loaded in the paper tray face up. For photo paper, always load the rougher side of the paper facing down.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.

Laserjet M603DN tray 2 not lifting
ANSWER : I had a similar issue with a M602, though it’s the previous generation machine they are close in design. This one kept saying tray 2 lifting but there was not a sound of the motor even trying. My first thoughts were replace the lift motor then DC controller but it was replacing the formatter that fixed it after other parts made no difference.

Optional 250 Sheet Feeder Tray (Q5931A – Tray 3) Constantly "Jams"
ANSWER : You don’t say if the paper moves at all. That’s key in determining the cause. If it’s not moving, then try swapping the rollers with tray 2. If it is moving out of the tray, then that would indicate there is some obstruction it is hitting on its way out of the tray. Hard to troubleshoot remotely when one doesn’t have specific details since we can’t see what is occurring.
