HP LaserJet M630h Enterprise MFP

If the product is not correctly functioning, complete the steps (in the order given) in the following checklist. If the product fails a checklist step, follow the corresponding troubleshooting suggestions for that step. If a checklist step resolves the problem, skip the remaining checklist items.

1. If the control panel is blank or black, check the following before proceeding:
   • Check the power cable.
   • Check that the power is turned on.
   • Make sure that the line voltage is correct for the product power configuration. (See the label that is on the back of the product for voltage requirements.) If a power strip is in use, and its voltage is not within specifications, connect the product directly into the electrical outlet. If it is already connected into the outlet, try a different outlet.
   
   If the control panel is not responding to touch, or if it appears black or blank, look for the following conditions.
   NOTE: The following conditions indicate that the product has froze while in Sleep mode (opening a door or tapping the control panel causes the product to wake up it it is in Sleep mode).
   • The control-panel home button LED is illuminated.
   • The power-switch LED flashes once every three to five seconds
   • The product does not exit Sleep mode when a page is placed in the document feeder.
   • The product does not exit Sleep mode when the document feeder is opened to place a page on the scanner flatbed.
   a. Try upgrading the firmware. If the firmware upgrade fails to resolve the problem, and the product still freezes while in Sleep mode, elevate the case after collecting the following info:
   • Try printing to the product from a host computer. Does the product print a page?
   • Is the product HP Embedded Web Server (EWS) accessible?
   • Turn the product power off, and then on again. Save the product diagnostic file.
   b. If the product did not freeze while in Sleep mode, verify that the control panel is correctly functioning by accessing the control panel diagnostics (see the Control-panel checks section of the product problem solving manual).
   If the control panel does not respond to the diagnostic button, try the following:
   • Turn the product power off.
   • Reseat the cable connections on the bottom of the control-panel assembly.
   • Remove, and then reseat the formatter.
   • Turn the product power on, and then check for functionality of the control-panel.
   c. Verify that the formatter is firmly seated. Check the contol-panel cables and connectors at both ends of the cables.
   d. If the error persists, replace the control-panel assembly.
2. The control panel should indicate a Ready, Paused, or Sleep mode on status. If an error message displays, resolve the error.
   • Use the Power-on checks section in the product troubleshooting service manual to solve the problem.
3. For network connection errors, check the cables.
   a. Check the network cable connections between the product and the computer or network port. Make sure that the connections are secure.
   b. Make sure that the cables are not faulty by trying different cables, if possible.
   c. Check the network connection.
4. Print a configuration page. If the product is connected to a network, an HP Jetdirect page also prints.
   a. From the Home screen on the product control panel, scroll to and touch the Administration button.
   b. Open the following menus:
   • Reports
   • Configuration/Status Pages
   • Configuration Page
   c. Touch the Print button to print the page.
   • If the pages do not print, check that at least one tray contains paper.
   TIP: Make sure that the selected paper size and type meet HP specifications. Also open the Trays menu on the product control panel and verify that the tray is configured correctly for the paper type and size.
   • If the page jams in the product, follow the instructions on the control panel to clear the jam.
   • If the page does not print correctly, the problem is with the product hardware.
   • If the page prints correctly, the product hardware is working. The problem is with the host computer, with the print driver, or with the program.
5. Print a supplies status page and then check that the maintenance items below are not at their end-oflife.
   TIP: If a maintenance item needs to be replaced, order the part number provided below.

   b. Open the following menus:
   • Reports

7. Print a short document from a different program that has worked in the past. If this solution works, the problem is with the program. If this solution does not work (the document does not print), complete these steps:
   a. Try printing the job from another computer that has the product software installed.
   b. If the product is connected to the network, connect the product directly to a host computer with a USB cable. Redirect the product to the correct port, or reinstall the software (make sure to select the new connection type).
