We loaded new pack of paper now printer tells me to load tray 1 as if it does not know that tray 2 is in place and loaded with paper.

Insert the Hp CD and follow the onscreen instructions.

its not reading there is any paper in the slot so will not load from this draw. the is a switch that when paper is installed it lifts it to tell printer paper loaded. like any switch they can fail.

Load specialty paper Follow these steps to load specialty paper such as card stock, envelopes, photo paper, or labels.
Before you proceed, verify that your printer supports the specialty paper on which you are attempting to print by viewing the product specifications . If the size, type, or weight of the paper is not available, the printer does not support printing it. Also note the tray loading capacity for the type of paper on which you are attempting to print.

1. Remove the packing material from the printer.

• 1. Remove the all orange tape from the outside of the printer.
  
• Remove orange tape from paper tray 2.
• Remove the orange packing tape from inside paper tray 3.
• Remove the spacer from inside the print cartridge area.

1. Load all paper trays.
2. 1. Pull the paper trays completely out of the printer.
   
3. Press the blue tab on the rear paper length guide and adjust the rear guide so that the pointer matches the size of the paper to be loaded.
4. Move the side width guides outward to match the desired paper size.
5. Add the media to the paper trays, make sure that it is flat in the tray at all four corners. Keep the media below the height tabs on the sides and rear of the tray. Push down on the metal lift plate to lock it in place.
6. Slide the trays back into the printer.
7. Install the print cartridge.
8. 1. Remove the print cartridge from the packaging.
   
9. Rock the print cartridge back and forth several times to "mix" the toner.
10. Pull the sealing tape from the end of the print cartridge to remove the entire length of the tape.
11. Open the top cover.
12. Slide the print cartridge into the unit.
13. Close the print cartridge door.
14. Connect the LAN cable (optional). (HP LaserJet 2420n, 2420dn, 2430tn, and 2430dtn models only)
15. Connect the power.

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.

Since tray 2 works, I'd guess that each drawer has a "paper sensor" that sees that paper is in the drawer. You might pull both drawers all the way out, with a flashlight, if needed, look at the area inside of each where paper is fed and you can compare #2 with #1, since you know 2 is good. You may find a sensor out of place. If it's not something simple like it popped out of place, then you may need to put in a new sensor. Good luck, please rate this if it helped.

Dell 3100cn Color Laser Printer Error 024-965 - Load Tray 1

Cause:
The "Paper Tray Inserted" sensor buttons are not being depressed by the Paper Tray so the Printer thinks no Tray is inserted even if the Tray is properly inserted.

If you pull out the paper tray and look at the Paper Tray opening, you will see three white vertical sensor buttons along the left-hand side at the mouth of the aperture where the paper tray slides in. These three white vertically aligned push button sensors tell the printer that the Paper Tray is inserted when the paper Tray is
properly pushed all the way in and aligned. It also signals to the printer by noting which button is depressed whether the tray is a Letter Size or Legal Size tray that has been inserted. These buttons which are fully visible as soon as the tray is slid out can move out of place and even fall into the wall of the Tray slot preventing the buttons from sensing the tray.

Solution:
Click it back into place. There should be no play and the buttons themselves should be the only thing that move and then only in an in and out manner. They should move out toward you when the Tray is removed and be pushed in when the tray in slid into the paper tray feedering slot. A pair of needle-nose pliers may be necessary to draw the button module out of the tray slot wall if it has fallen in. Once it is STIFFLY repositioned and the Paper Tray reinserted, reset the printer by opening and quickly reshutting the printer cartridge compartment. This action will recalibrate the printer, shut off the amber error light and resume the current printing job if one was in progress.

Good luck!

printer supports it. just you have to goto printing preferences or printer properties and set rear tray to accept glossy paper. it will accept size of paper ur using. so give the actual size.

u will just have to place a paper in a paper feeding tray.thats in the lower base.maximum you can load is 50 -- 100 papers.minimum is 1 --paper in the tray.

Linda,

On printer check media/paper type tray 2 or 3 is plain and tray 2/3 is set for letter paper size too, via printer control panel. Also check under paper handling other options for tray 1, also on tray 2 and 3, I think there is a blue little round switch on left should be set as letter not custom.

Some paper types cannot be feed from anywhere else but tray1/bypass ie labels/laminate/card stock.

Check print driver on pc has tray 3 option installed and is not set as default to print to manual bypass/tray 1

light flashing cause printer wants paper type/size that it "thinks" it hasn't got in tray 2/3

If that dont cover it...post back
