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.
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.
When the printer tells you to load tray 1 it means the size and or type of paper being asked by the print job does not match the same that the printer thinks it has in the tray.
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.
Open the input tray, and then remove the stack of paper from the tray. Remove any torn pieces of paper, or jammed paper, from inside the tray. Replace the stack of paper in the tray, and then close the tray. Check if the noise comes from the input tray.
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.
Gently press on the edge of the extender that is inside the paper tray. The extender should give slightly. It`s now loose. Remove the tool and close the extender.
The Load Tray 1, Tray 1 Missing, or Insert Tray 1 error messages indicate that the printer has failed to detect the tray. The Tray Low or Tray Empty errors indicate that one or more of the tray sources are empty or low.
Improve printer performance by selecting the optimum paper type for the tray. You can select from the following paper types: Tray 1. [Thin Paper], [Thick Paper 1], [Thick Paper 2], [Plain Paper], [Recycled Paper], [Color Paper], [Preprinted], [Prepunched], [Letterhead], [Bond Paper], [Cardstock], [Label Paper]
This usually occurs when one or more toners are not fully seated. Most times it is the black cartridge lock on the left side breaks so the black toner cartridge is sitting a bit out on the left side and the door will not close. Easy to tell. Just remove all the toners and see if you can close the door.

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 jam in tray 2 (but no paper pulled from tray) also M476DN models
ANSWER : Isopropyl alcohol is not recommended for rubber rollers. It dries out the rubber and hasten it’s cracking and breaking. It will do nothing to restore the grip. Those rollers are really hard to replace. It would be easy if that dumbass secondary menu really worked. None of the techs I’ve spoke to ever got into it. Everyone I know sends a print job and listens for the roller to rotate into position where you can pull it off.

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.
