The common reasons for this issue are various, for instance, the paper input tray is overloaded, dust or moisture can affect the paper feed or paper pick rollers, the printer driver is old, etc. Thus, the printer cannot detect the paper that has been inserted into the tray.
Sometimes power cycling your printer can resolve the issue. Turn off your printer and unplug it, wait 30 seconds, plug your printer back in, and then turn the printer back on.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
There are a few things that could be the cause of this problem, including: Empty ink or toner cartridges that need replacing. Ink or toner cartridges that have become dislodged from their proper place. The wrong paper size loaded in the input tray.
Paper Overloading

Because many desktop inkjet printers are top-loading, it can be easy to overload the tray.

The most common cause of this issue is paper misalignment. Make sure you properly insert the papers in the tray and avoid overfilling the tray. If this doesn`t solve the problem, check the troubleshooting section of the printer`s user manual.
Use the operator panel on the printer to enter the menus. Locate the Paper Menu and select that menu. Locate the Paper Size/Type setting and select that. Find and select MP Feeder or Multipurpose Feeder and select that.
Click: `Open the HP Photosmart Toolbox` or: `Service this device` Click: Device Services tab. Click: Calibrate the Device or Clean the Print Cartridges or Align the printer. Follow the instruction which will appear on-screen.
Several factors may cause the product to print blank pages, such as print settings, low ink, or the product itself. Check the following: Make sure the product is placed on a flat, stable surface that extends beyond the base in all directions. The product won`t operate properly if it`s tilted or at an angle.
Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.
Signs of a bad transfer roller include streaking, squealing, jamming and odors emanating from the printer. Troubleshoot your transfer rollers to restore your prints to their normal high quality.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.

Paper jam in tray 2 (but no paper pulled from tray) also M476DN models
ANSWER : Isopropyl alcohol is not recommended for rubber rollers. It dries out the rubber and hasten it’s cracking and breaking. It will do nothing to restore the grip. Those rollers are really hard to replace. It would be easy if that dumbass secondary menu really worked. None of the techs I’ve spoke to ever got into it. Everyone I know sends a print job and listens for the roller to rotate into position where you can pull it off.
