Printer is not taking paper from tray automatically

in the menu system of the printer you have to set the tray to "FIRST"
and you have to have a piece of paper loaded in the "bypass" (MANUAL) feed first BEFORE sending the print job.

You'll have to change the paper TYPE of tray 3 to a different type as in tray 2.

For the majority of the Lexmark printers, all that needs to be done is to set the paper size and type the same for each drawer. Example - drawer 1 & 2 sizes are set to letter, drawer 1 & 2 paper types are set to plain. Set up this way, when drawer 1 empties, the printer will automatically switch to drawer 2 to supply the paper.

Sounds like you have a mismatch in the paper you are trying to print on and the paper that is loaded in the printer. HP printers look to feed paper from tray 1 anytime the computer settings don't match the paper loaded in tray 2. Tray 1 is the multi purpose tray and prety much any size paper can be loaded in tray 1. Double check your document settings and double check the paper size loaded in the paper tray 2 and make sure they match. Also try printing a different document to see if the error persists. If it does this on everything you try to print you should also double check teh rear guide in the paper tray. There is a rear guide in paper tray 2. If it slides back too far it will make the printer think that paper longer than 8 1/2 x 11 is loaded. Push the paper all the way forward in the tray and push the rear guide until it is snug with the tail end of the paper stack.

"MP" tray is refering to the top fold down tray on the front of printer (bypass tray) You might load paper in the bypass and see what it does?

The 4100 will look at tray 1 first then tray 2 If tray 1 is empty it will pull from tray 2 if the papersize matches the job otherwise back to tray 1 and ask for the paper.
Your machine likely thinks the paper in tray 2 is not the size you want. For instance you have LETTER in tray2 But the machine thinks it is legal.
The LJ 4100 detects the paper size in tray 2 automatically. If you print a configuration page:
MENU them INFORMATION then ITEM then CONFIGURATION PAGE then SELECT.
The page will print and show what size paper the machine thinks is in Tray 2 if it says LEGAL and you have LETTER you need to Check The Paper Backstop in TRAY 2.
The back stop sets the length of the paper if it is not at Letter (8 1/2 x 11) the machine will not detect LETTER. Even if it just a little bit off or between positions.

If it is set at LETTER then you may have bad switches in the machine that are operated by the tray.
Or the arms on the tray that operate the switches are not moving properly.
You will find the arms on the rt, side of the tray and feel them change position when you move the backstop.
Hope this helps.

You can do one or a nother thing. You can change the paper size in paper tray 3 to Legal size or you can go into the user settings, under addtional funcation and choose, that tray 3 will not daisy chain when tray 2 is empty or you can make tray 3 not to be able to print too.

Verify your settings under the Paper Menu are correct as far as size and type. All trays with same size and type settings are automatically linked as per the User Guide.

1-Is the paper set correctly in the tray? if you have Letter paper in it make sure the guides are snug against it

2-Check the lever inside the tray, remove the tray and look at the tires there should be a lever that you ca move freely that is the paper sensor
