Step 1
Check how much paper is on the tray. If you are experiencing frequent paper jams, make sure that you are not exceeding the maximum tray capacity. According to the HP user guide, the HP Officejet 4315 can only handle 10 mm of paper in the paper tray.

Step 2
Remove any paper jams if you are experiencing an error message on the display on the front of the printer. To do this, lift up the automatic document feeder located on the front of the printer. Then, gently pull the paper from the rollers.

Verify that the phone cables are properly inserted into the wall jack and the back of the printer if you are receiving a "Phone off the hook" error message.

Step 6
Perform a semi-full reset if the partial reset did not work. To do this, unplug the power cord. Hold "#" and "6" buttons while plugging the cord back in. Then, release the buttons and try to rescan or reprint your document.
