Paper Jam
The HP Officejet 4650 Printer may display an error message if there is a Paper Jam in Printer. If the message happens, remove all of the paper from the paper plate. Gently remove the jammed paper to avoid ripping and make sure no parts are left behind. If the paper jam is interior, make sure to switch off the printer by unplugging the power string. Then, elevate the scanner glass door to expose the ink cartridges and the inner paper jam. To avoid ripping, make sure to utilize both hands to remove the jammed paper.
Loss of Power
If the printer drops power while printing, verify that the power cord is correctly inserted into the printer and the power plug.
