Clear jams
Common causes of jams
Cause
Solution
The paper length and width guides are not adjusted correctly.

Adjust the guides so they are against the paper stack.
The media does not meet specifications.


Use only media that meets HP specifications. See
Do not use media that has been previously printed on or copied.
You are using media that has already passed through a printer or copier.
An input tray is loaded incorrectly.


Remove any excess media from the input tray. Ensure that the stack is below the maximum stack height mark in the tray.


The media is skewed.

The tray guides are not adjusted correctly. Adjust them so they hold the stack firmly in place without bending it.

The media is binding or sticking together.



Remove the media, flex it, rotate it 180°, or flip it over. Reload the media into the input tray.
NOTE: Do not fan paper. Fanning can create static
electricity, which can cause paper to stick together.


The media is removed before it settles into the output bin.

Wait until the page completely settles in the output bin before removing it.


The media is in poor condition.
Replace the media.


The internal rollers from the tray are not picking up the media.

Remove the top sheet of media. If the media is heavier than 176 g/m2 (47 lb), it might not be picked from the tray.
The media has rough or jagged edges.

Replace the media.

The media is perforated or embossed.


Perforated or embossed media does not separate easily. Load sheets one at a time.


Media was not stored correctly.
Replace the media in the trays. HP recommends that media should be stored in the original packaging in a controlled environment.

Change Jam Recovery setting
When the Jam Recovery feature is turned on, the product reprints pages that are damaged during a jam.
Use HP ToolboxFX to turn on the Jam Recovery feature.
1. Open HP ToolboxFX.
2. Click the Device Settings folder, and then click System Setup.
3. Next to Jam Recovery, select On from the drop-down list.
Solve connectivity problems
Solve direct-connection problems

If the product is experiencing connection issues while directly connected to a computer, complete the following steps:
1. Ensure that USB cable is no longer than 5 meters (16.5 feet).
2. Ensure that both ends of the USB cable are connected.
3. Ensure that the cable is a USB 2.0 Hi-Speed-certified cable.
4. If the error persists, use a different USB cable
Service mode functions
Service menu

Use the control-panel Service menu to troubleshoot device problems.
Service menu settings
The Service menu is used to calibrate, restore factory default settings, and clean the print paper path. The following Service menu items are available:
# Restore defaults — used to reset all customer-accessible menu settings back to the factory default settings (except language) using the control panel or software
NOTE: This service menu item does not reset factory-settable settings, including formatter number, page counts, factory paper settings, language, and so on.
# PowerSave — used to configure the amount of idle time before the engine enters sleep mode
# Cleaning mode — used to remove dust and toner from the print paper path
Restore the factory-set defaults
1. Press OK to open the menus.
2. Use the Left arrow or the Right arrow button to select Service, and then press OK.
3. Use the Left arrow or the Right arrow button to select Restore defaults, and then press OK.
The product automatically restarts.
Secondary service menu
Use the secondary service menu to print service-related reports and to run special tests. Customers do not have access to this menu. Open the secondary service menu
1. Ensure the product is in the Ready state.
2. Press OK to open the menus.
3. Simultaneously press Left arrow and OK to open the secondary service menu.
4. Press the Left arrow and the Right arrow to navigate through the menu.
Display test
Use this test to verify that the LEDs and characters on the control-panel display function correctly. At the beginning of the test, each of the LEDs illuminates one-at-time. Press OK to continue to the next LED. After the LED test is complete, the character test begins by testing the pixels on each line. Then, each of the 255 characters displays in groups of 16. Press OK to continue to the next group of 16 characters. You can cancel the test at any time by pressing X.
Cold reset
The traditional cold reset function found in other HP LaserJet products is not supported for this product. The equivalent function is the Restore defaults option in the HP ToolboxFX or the Service menu. A cold reset unlocks menus that have been previously locked and resets all control-panel menu items to the factory defaults. It does not reset the serial number and the page counts.
NVRAM initialization
1. Turn the product off.
2. Simultaneously press the Right arrow button and the X button. Keep these buttons depressed as you turn the product on.
3. When Permanent storage init. appears on the display, release both buttons.
4. When the product has finished the NVRAM initialization, it returns to the Ready state.
