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. Slide the paper-width guide to its widest position, and then pull out the paper tray extender. Figure 2: Move the paper guides
2. Insert plain white paper into the input tray with the short edge forward and the print side down. Slide the paper forward until it stops. Figure 3: Insert paper into the product
   CAUTION: Make sure the product is idle and silent when you load paper into the input tray. If the product is servicing the print cartridges or otherwise engaged in a task, the paper stop inside the device might not be in place. You could push the paper too far forward, causing the product to eject blank pages.
3. Slide the paper-width guide inward until it stops at the edge of the paper. Figure 4: Adjust the paper guides
   NOTE: Do not overload the input tray; make sure the stack of paper fits within the input tray and is no higher than the top of the paper-width guide.

Loading your paper
Paper loading tips:
● Load paper with the side to be printed facing down.
● You can print photos and documents on a wide variety of paper sizes, from
8 x 13 cm (3 x 5 inch) up to 22 x 61 cm (8.5 x 24 inch). The 10 x 15 cm
(4 x 6 inch) photo paper is available with and without tabs.
● Before loading paper, pull the Main paper tray out (use the Main tray release or
the tray grips) and slide out the paper-width and paper-length guides to make
room for the paper. After loading paper, adjust the guides to fit close to the edges
of the paper without bending the paper. When finished loading paper, push the
Main tray back in all the way.
● Load only one type and size of paper at a time in the same tray.
● After loading paper, extend the Output tray extension to catch your printed pages.
Use the directions in the following table to load the most commonly used paper sizes

I have the HP C7280 and I was able to fix the problem.
HP seems to have 3 trays. The bottom tray is for the paper. The middle one has a small blue tray for the photos and the top tray is where the paper comes out.
Well I lifted the top tray where the paper comes out (it can angle up) and then I clicked OK on the problem. I may have even rebooted, but then I got a new error message which is good. It said to push photo tray (the small blue tray) all the way in which I pulled out and pushed back in. Then I pushed the top tray down so all is flat again. I clicked OK and it re-calibrated with no more error messages! Hope this helps.

On that printer, you can't pull out the main tray. This video shows how to clear a paper jam on the C7280.

There are two possible solutions for this problem.
Usually it is due to the pickup roller wearing or becoming contaminated with toner or paper dust.
Simple solution, clean the pickup roller, the best thing for this is WD40, put a very small amount on a clean cloth and wipe the roller underneath the printer. Use a clean dry piece of cloth to wipe off any residue.
More complicated solution, remove the roller and reposition, you will need two small flat-bladed screwdrivers to pry apart the retaining clips, remove the roller, a tight squeeze beneath the laser housing, reposition and clean as above then refit the roller. You should find that the paper is picked up cleanly once again.

I hope this helps,
