Our sources include academic articles, blog posts, and personal essays from experienced technical support :

just GOTO settings > printer properties of your printer > preferences>paper quality >change the paper to A4 size . and restart the printer.
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.
Under Hardware and Sound, click Printer. 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.
Sometimes paper can get stuck behind the tray and get stuck in the sensors and arms that detect paper size and detection. You can remove the tray completely from the machine and look at the feed unit and rollers and make sure there is no obstruction or paper stuck.
The paper might not be engaged with the feed rollers. The paper-width guide is pressed against the paper stack too tightly. The paper tray is not completely inserted into the product. The paper settings in the print driver do not match the paper loaded in the paper tray.
Tray 2 holds up to 250 sheets of 75 g/m2 paper.
Open the System Setup menu, and then open the Paper Setup menu. Select the tray that you want to configure. Select Paper Type, and then select the desired paper type for the tray. Select Paper Size, and then select the desired paper size for the tray.
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]
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.
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.
To specify a tray within MS Word the user must: Click File and then Print. In the Print Dialogue click Page Setup. In the Page Setup window click on the Paper tab.
The bypass tray is intended primarily for small-quantity jobs using special media. The bypass tray is on the left side of the printer.
Paper is housed in the printer`s paper tray, and most trays can be found along the bottom of the printer. There is usually a small notch on the face of the tray that pulls out so you can insert the paper. Within the paper tray, you will notice a guide that can be adjusted to fit your preferred paper length.
The extra time needed to pick the sheet of paper incorrectly leads the product to `believe` that the piece of paper pulled from Tray 2 is actually longer than it is. Depending on how much extra time was needed to feed the sheet, the product may jam and/or display the Unexpected Size error.

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.

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.

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.

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.

Paper tray jammed
ANSWER : Check from the back of printer to see if some paper lodged at top of tray and has jammed it up – you may be able to work it out from the back side. If not you may have to partially disassemble the printer and/or tray to get the tray out.

Printer stops pulling paper from tray 2 after a few sheets
ANSWER : Sticking pickup roller solenoid. Pretty easy fix. You need to remove the right side covers. The back one just slides off, but the top holds the front one. I usually just take the 2 right side screws off and gently lift the top enough to pop off the side panel. Open the metal door on the formatter assy. Then release the tab in the middle. There’s also a tab at the front of the panel. When putting it back on, make sure you engage the rocker switch and the metal rod before pushing it into place. When you get it open, you’ll see the solenoid at the bottom front. There’s 1 screw holding it in place. Remove it and take the top plate and spring off. Be careful not to lose the spring. Then scrape off the gooey crap on top and clean off the plate as well. I put a piece of thin sticky backed felt in place of the remnants of the disintegrating sponge that HP uses. You can find it at the hardware store used for the bottom of chair legs.
