The common reasons for this issue are various, for instance, the paper input tray is overloaded, dust or moisture can affect the paper feed or paper pick rollers, the printer driver is old, etc. Thus, the printer cannot detect the paper that has been inserted into the tray.
Right-click your product, and then select Printing Preferences. From the Printing Preferences menu, select Paper/Quality. From the Paper Source drop-down menu, select Tray 2.
Insert the stack of paper into the product, and then gently push the paper guides snugly against the paper. Make sure that the paper is fully inserted into the product. Try printing again. If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time.
Paper Overloading

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

Paper Jams

This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.

Generally when the printer tells you to print to tray 1 it means the job being sent to the printer is asking for a paper size and/or type that the printer does not think it has in any tray. Check you paper size and type settings for trays 2 and 3 and then check what each job is asking.
Click the Copy/Print or Print tab. Open the Manage Trays menu. Modify the tray settings.
Most common culprits for a clogged printhead are microscopic dust particles, air bubbles or dried ink. Running a printhead cleaning on your machine will clear the print nozzles of excess or dried up ink.
This will be used to prevent like paper from being fed if Auto Switching is ON. Press Printer Setup > Tray Settings > Settings > Tray Protection. Choose a tray and press the button to activate this function.
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
Using both hands, put one piece of paper in the manual feed slot until the front edge of the paper touches the paper feed roller. Once the machine has grasped the paper, let go. The side to be printed should be faced up. The machine will hold the paper in place until the print data is sent to the machine.
The cause: a tiny spring, intended to load the paper intake rollers, is inadequately weak. The intake / feed-in rollers just slide around on top of the paper instead of gripping it and pulling it into the print mechanism. The solution: a bit of sponge (seriously).

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.

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.

Tray 1 (upper tray) paper feed problem
ANSWER : There is no way of adjusting the distance of lift. Could be that the pickup roller is worn enough that it will pick up a sheet that is higher, but not one that is lower down. You can look at the end of the roller that first makes contact and see if it is worn smooth.

Paper tray 3
ANSWER : What usually happens in this instance is that the access flap to the left of the pickup roller pops up. This blocks the tray from opening. The only way to fix it is to look in from the back of the tray with a flashlight and get something thin and long, maybe a wooden ruler? Reach in and push down on the flap until it locks in place. If you’re not sure what I’m referring to, you can pull out and look at tray 2 for guidance.
