What you are describing sound like the solenoid plate and return spring. If you look at the plate itself, you’ll see a lip curling up on one end and there are 2 slots on the sides at the other end. The lip is what stops the roller from turning until the solenoid pulls the plate down. The slots go on the 2 poles sticking up on the solenoid with the lip pointed up. Then you hook the spring on the 2 metal tabs one on the solenoid body and the other between the 2 slots at the back of the plate.

Tray 2 holds up to 250 sheets of 75 g/m2 paper.
Most likely the pickup roller is worn. You cantry cleaning with warm soapy water and try. If that does not work then the roller needs to be replaced. Not that hard, just do a google search for instructions and where to purchase tray 2 roller.
The solenoid is an activator for the paper pickup drive assembly, it is usually about as big as a thumbnail, and it`s a metallic device with a spring and a hook which clips onto the pickup roller drive gear. These solenoids “click” on and off constantly to allow the gear to spin and drive the paper feed.
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.
One sensor is located in the printer carriage. A second sensor—the Auto Sense sensor—is located in the back of the printer near the paper `clean out` area. Each sensor performs a specific set of media detection functions.
Check That the Paper Tray Is Full (Not Jammed)

Sometimes, printers are finicky—there may be paper loaded, but if the printer can`t grab hold, it`s going to think it`s empty. Try removing the paper tray, re-aligning the paper, and sliding it back in. In other instances, there may be some paper jammed in the mechanism.

Solenoid issues may cause your vehicle to go into “limp mode,” a mode created to shield your engine and transmission from catastrophic failure and a severe accident. In Limp Mode, the entire vehicle will begin to grow weak in its power and the ability to accelerate.
The paper starts to feed into the printer, then stops. You may hear a crumpling sound as the paper gets stuck and crumpled up inside the printer or paper tray. Paper feeds into the printer; the printer starts to print, then printing stops, and the paper remains in the printer.
Paper jams

A piece of paper stuck in the paper tray or inside the printer can create a paper jam.

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.
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.
If roll paper does not feed, cut the end straight across and uncurl it by rolling it backward, if necessary. Then reload the paper. If thick media does not feed, make sure you are loading it straight into the product, not at an angle. If paper jams when you print on both sides of the paper, try loading fewer sheets.
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.
There are different methods of paper feeding. 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.
Your printer has a paper type sensor that detects the following paper types and automatically adjusts the paper type setting in the Print dialog: Plain. Coated. Glossy/Photo.
If the paper guides are too tight, the paper might be held in the tray and not allowed to feed into the product. Try the print job again.
The Print Spooler is software built into the Windows operating system that temporarily stores print jobs in the computer`s memory until the printer is ready to print them. In some circumstances you may need to stop and/or restart the service.
Electromagnetic solenoid valves (otherwise also known as solenoid valves) are valves controlled by electric current. They consist of two main parts – the valve body and the solenoid (coil). The solenoid is composed of a wound copper wire that surrounds a core with a movable closing plunger.
When a solenoid is first energized, its coil receives a pulse of high inrush current that decreases as the plunger closes. If the plunger does not close, the high inrush current continues, which can cause the coil to overheat and burn out. This is the most common cause of solenoid failure and spotting it is easy.
A failed solenoid may be debilitating for your machinery or manufacturing process but, thankfully, it`s a part that you can often easily repair or replace once you`ve identified the root of the problem.
When it does, it usually entails replacing the complete starter motor which can range from under $100 to more than $450. On older cars, the starter solenoid is separate and less expensive, usually under $50, but it`s still aggravating when it fails.
Dirty printer rollers. If your paper jams are happening randomly and you can`t identify the cause, it could be that your printer rollers are dirty. Over time, dust and debris can build up on the rollers and cause the rollers to grab onto paper unevenly, which can lead to paper jams.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. 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.
Store paper in a dry and cool place.

Always make sure to store the papers away from the sun, heat, and humidity. These conditions can affect the quality of your paper, causing paper jams.

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.

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.

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.
