HP LaserJet 3200 Series Printers - Troubleshooting a 79 Service Error

ISSUE: A 79 error appears on the display of the HP LaserJet 3200 series product.
SOLUTION: 79 errors are generated in a number of ways. They may be the result of hardware failure of the printer or printer accessory, or a conflict generated by software.

Troubleshooting steps

Can the message be cleared? If unsuccessful attempts have been made to restore the printer to a ready state, verify that all of the steps listed below have been attempted to restore the printer.

NOTE: If the message can be cleared, bypass the hardware troubleshooting steps, and proceed to the software troubleshooting. When any one of the hardware troubleshooting steps restores the printer to an operational status, proceed to the next step.

Hardware troubleshooting

Each of the following steps is intended to determine whether the 79 error displayed on the printer is the result of a hardware failure. A hardware failure should not be diagnosed unless every step has failed in restoring the printer to normal operational status.

First, turn off the printer then turn it back on again.

If the message persists, proceed with the following steps, powering on between steps to determine if the error message has been cleared:

  1. Turn off the printer.

  2. Disconnect from the PC/network.

    NOTE: If the error message does not appear after disconnecting from the PC/network, yet reappears once it is re-connected, verify that the print queue on the PC/server has been cleared of all pending jobs.
  3. Turn off the printer and unplug the power cord before proceeding with the following steps. Remove any accessories that have been installed on the printer (for example, RAM DIMMS).
    CAUTION: For the HP LaserJet 3200 series product, only an additional memory DIMM (which would be in the first slot) should be left out. The regular firmware chip needs to be present in the back slot and a RAM memory chip in the middle slot; otherwise, the product will not function.

    If the 79 error disappears after removing all the accessories, start adding the accessories back one at a time to isolate which one is causing the issue.

    NOTE: The following step may cause an HP Jetdirect card to lose its configuration.
  4. Restore the printer to the factory defaults.
    NOTE: This process accomplishes several important functions: It restores all settings to factory settings, including the fax header); it clears unprinted data, current incoming and outgoing fax jobs, and current copy jobs from the product's memory; and it removes factors that may cause many errors.
    1. Press the Enter/Menu button.

    2. Press < or > until Service is displayed on the control panel display and then press Enter/Menu .

    3. Press < or > until Restore Defaults is displayed on the control panel display and then press Enter/Menu .

    4. Press the Enter/Menu button to confirm the selection.

  5. Clear fax memory.
    NOTE: In addition to clearing the reprint memory, this procedure clears faxes that are currently being sent, unsent faxes pending redial, faxes scheduled to be sent at a future time, and faxes that were not printed or forwarded.
    1. Press the Enter/Menu button.

    2. Press < or > until Fax Functions is displayed on the control panel display and then press Enter/Menu .

    3. Press < or > until Clear Stored Faxes is displayed on the control panel display and then press Enter/Menu .

    4. Press the Enter/Menu button to confirm the deletion.

  6. Check the power source and verify the unit is plugged directly into a wall outlet, especially if the printer is located in an older building. Inadequate or bad power can play a major part in causing 79 service errors.

  7. Reseat the printer DIMMs (for the HP LaserJet 3200 series product only).

  8. Verify that the phone cord that shipped with the product is the one attached to the product.
  9. Update any out-of-date firmware versions. Flash firmware directly from the HP's Drivers and Downloads page .

  10. If all of the above steps have failed to restore the printer to a ready state, the printer should be serviced.
    NOTE: If the problem is intermittent, there is not a fix at this time. Repairing or replacing the product will not fix the issue. In this case, document any sub codes associated with the error and document the specific steps performed when the error occurred.

Software troubleshooting

NOTE: Many software-related 79 service errors are ambiguous and may be difficult or impossible to re-create in a testing environment. Due to this fact, solutions or workarounds may not be possible for all software-generated 79 errors.

The following scenarios are intended to identify specific conditions that cause 79 service errors, or provide several setting adjustments that may eliminate the error message.

Error occurs when printing from a specific environment (for example, Windows, UNIX, Mainframe) or application

  1. Print from a different application. If the 79 service error is caused by a particular file and is repeatable, get the file and the secondary code from the customer and create a technical escalation.

  2. Print different documents within the same application.
  3. Change the Graphics Mode in the Printer Properties.

  4. Change the Resolution setting in the Printer Properties.

  5. Select a PostScript driver instead of PCL, if a PostScript-ready printer is being used, or vice versa (Windows only).
  6. Select a Microsoft PCL driver (Windows only).
  7. Use a different font, if possible. (Font selections may not be accessible in some environments or applications.)
  8. Adjust the margin settings, if possible.
  9. Print an Event Log from the printer's Control Panel (if available) and check for PCL XL errors. If a PCL XL error is associated with the 79 Service error, troubleshoot the PCL XL error first to see if it resolves the 79 Service error.

Error occurs when printing a specific document

  1. Change the Graphics Mode in the Printer Properties.

  2. Change the Resolution setting in the Printer Properties.

  3. Select a PostScript driver instead of PCL, if a PostScript-ready printer is being used, or vice versa (Windows only).
  4. Select a Microsoft PCL driver (Windows only).
  5. Use a different font, if possible, or utilize fewer font changes.
  6. Adjust the margin settings, if possible.
  7. If graphics are used, try using fewer graphics on each page or rearrange the graphics on the page.
  8. Recreate the document.
    NOTE: If possible, send the file to HP Customer Care for testing.
