HP LaserJet Error Messages A - E

Message on printer display	What it means	What to do
ACCESS DENIED MENUS LOCKED	The control panel function you are trying to use has been locked by the network administrator to prevent unauthorized access.	1. Ask the network administrator to unlock the function. 2. Perform a cold reset. This will reset the printer to factory defaults. If a JetDirect network card is installed it will also reset the IP address and other settings so you might want to remove the JetDirect before performing the cold reset.
BAD DUPLEXER CONNECTION	The duplexer is not correctly installed.	1. Some printers need a right-angle power cord for a duplexer to be installed correctly.   Make sure right-angle cord is installed, if needed. 2. Turn the printer off. 3. Remove and reinstall the duplexer. 4. Turn the printer off and back on. 5. If the message persists, make sure the duplexer is connected and the connector is not damaged. 6. Replace the duplexer.
CHECK INPUT DEVICE alternates with PAPER PATH OPEN PLEASE CLOSE IT	The optional input tray cannot feed print media to the printer because a door or paper guide is open	1. Check the doors and paper guides and close any that are open. 2. If doors and trays are closed, check tabs and sensor levers in the tray for proper operation. Replace any defective tabs or sensors. 3. Replace the PCA controller in the feeder. For 5si, 8000, 8100 series make sure C-link cable is correctly hooked up. Also on the 5si check the paper accessory PCA.
CHECK OUTPUT DEVICE alternates with CLOSE OUTPUT DELIVERY PATH	The optional output device is not properly connected to the printer.	1. Ensure the optional output device is fully seated and properly installed. 2. Check any doors on the output device and verify they are closed.  For 5si, 8000, 8100 series make sure C-link cable is correctly hooked up.
DISK DEVICE FAILURE	The EIO disk had a critical failure or fatal error.	1. Reseat the EIO disk. 2. Remove the EIO disk and replace it with a new one. 3. A bad formatter assembly could also cause this error, replace if needed.
