Printer trying to feed from manual feed tray
Even though your system may show that your preferred tray (usually 1 or 2) is set to 8.5" x 11", occasionally the printer will start looking to other trays to find that size. The fix for this is usually very simple.
1. Open the tray
2. Make sure the paper is in a tight stack and not staggered along the edges.
3. Adjust the tabs that hold the paper in the tray so they are tight against the paper. If the tab is off by even 1 notch, the printer may sense that it is not set to 8.5 x 11 and look elsewhere.
Printing is slow
Unplug the power for the printer, wait 10 seconds, then reconnect power, and try your print job again.
Waiting 10 seconds while the power is removed (power-cycling) from the printer sometimes helps clear the memory and get back to normal printing.
Printer error ie: 82.0180 EIO 2
On the back of the printer where the network cable plugs in is a card that is held in with 2 thumb screws. Turn off the printer then loosen those two screws and gently but firmly pull the card straight out. Slide the card back in and tighten the screws. Turn on the printer and see if the problem persists.
