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.

Have you checked that the printer is selected and ticked as being the default printer - also check that all the correct trays are opened and ready for use - some machines give a choice of top loading paper or front loading - paper needs to be in the selected tray in this case

If you put regular paper in the tray as it is asking does the printer use the regular paper to print the picture? If so, be sure the 4x6 photo paper tray (with photo paper) is pushed all the way in, and when you select print there should be an option (probably hidden in a submenu) to select the photo tray as the paper source. If you are printing from Adobe Acrobat, I have not found a reliable way to get the c6180 to use the photo paper tray. I hope this helps.

What does the display say? I would check the paper trays first. There is a dial on the front right after you open the tray. This has to match the orientation of the paper in the tray.

disconnect all usb cable from computer .power off again power on
press & hold down go button press t times if print , reset printer drive in your computer or not print test page replace drum unit .

check if there is a paper at tray 1. if so, may be the printer is unable to pick up paper due pick-up roller problem. try to remove the tray and look in the middle, there should be a rubber like roller. if its too glossy it cant pick the paper.

Thank you for contacting FixYa with your printer inquiry.
This is a common problem. The device can be set to print from tray 1 if it is loaded, or to print only from tray 1 if the type of media selected is other than standard bond.
Pull out tray 2 and make sure the paper size adjustments are properly set to match your size of paper. If you are using std bond and the adjustments are set to A-4 it won't pull paper.

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
into the printer.

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.

OK, I was having a similar problem: Tray full of paper and tray adjusted properly.

Whatever I tried, the printer kept saying load paper.

I went to print menu>properties button (windows XP this is next to the printer name)>paper source tab.

It tuned out that the paper source had been changed from cassette to multi-purpose tray.

Change it back to cassette and you should be golden.
