Just push the scanner hinge forward, and it should pop off, granting you easy access to the four additional screws along the back. Using your T10 bit, remove the eight screws on the front of your printer. These can be purchased at your local hardware store, or here through BCH Technologies. Step 4Īt this point, you will need to grab T10 and T6 screwdriver bits. If it doesn’t come down after being lifted, you know there’s a problem there. Paper will raise this lever, but once it’s removed, the lever will snap back into place. The second sensor is the paper ejection sensor, controlled by a lever in the middle. Of course, if everything else is physically fine, the board itself may be malfunctioning. However, if it does not go forward at a 90-degree angle, it will still block the sensor, resulting in a printer error. If the tray lever moves forward, it will move out of its slot, unblocking the sensor. One of these slots is for the tray, and the other is for paper ejection.

The lever is mounted on a piece of electronic board with two slots. In the case of a lever assembly that’s over-engineered, if even one piece is just slightly out of place, it can block the lever from going all the way forward. Notice how the paper jam error message mentions the paper tray-this is why you should make sure that the sensor and lever are working in that area.

The first sensor in the back is a tray sensor.

There are little marks on the tape the printhead reads to determine its position.

There are two sensors in the back that sense the paper feeding. Luckily, HP printers do not contain very many sensors, so you should be able to determine the root of the problem fairly easily. Printer sensors can trigger error messages if they are malfunctioning. Once you’ve eliminated the possibility that a foreign object is causing the jam, you should turn your attention to the printer’s sensors. You might need to check underneath the printer and shake it out to dislodge any loose paper or other debris that may have gotten stuck inside. Make sure no label fragments have jammed up your printer before proceeding. Shut the printer off, get a flashlight, and try to see inside. Small fragments of sticky label material commonly get torn off and stuck within your printer, collecting dust and causing a jam. If you’ve recently printed label sheets, there’s an additional troubleshooting option. Sometimes, it can be easy to forget your paper levels, and there could be a piece of paper that got stuck in the printer, so it never hurts to double-check.
