HP Laser Jet 4100 HP Not pulling paper from Tray 2
Action: 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.

Is the light printing the same for black and white vs color? Light printing on a side is not uncommon for these printers. It is usually caused by the laser optics getting dirty. But this usually shows up more in one color than the other. Such as something printed in yellow is fine while red is faded on one side. If the light on the right side printing is the same on all colors including black then I would suspect something with your transfer unit.
If you do notice that it us just on black or another color then it is definately time to get the laser optics cleaned.

check the paper size in the printer driver settings.
this should also be set to letter.

The problem is usually caused by printing a PDF file with fonts/page size/ page formating errors which will cause the printer to display the 49.3048 error. The only way to use the printer is to POR or recycle the power and delete the print job from the server or spooling device and cancel it on the printer before the offending command is issued to the printer again. You can try updating the firmware to the latest version 46.140.5 from the HP website. MIke L.

Here is the real solution:

Click Printing Preferences
In Paper Source drop down, select Tray 2.

Leave Tray1 closed. Remove tray 2. Push down on green arrows visible after removing Tray 2. You should see the jammed paper on the plastic tray which becomes accessible after pushing down on the green arrows.

Check your fuser. It might be dirty.

paper jam on tray 1. How to open the back part of the printer.

Have you would try a different paper cassette.
Usually that clunking noise is associated with gears not mashing.
Is the lifter lifting the platform or not?
There might be something above the paper tray, maybe even the paper input assembly preventing the paper platform from reaching the top.
Check these and let me know what happens.

found problem ??
