HP Color LaserJet 4500 and 4550 Series Printers - 49.xxxx Errors

ISSUE: A 49.x service error appears on the HP Color LaserJet 4500 or 4550 printers display, and other unexpected errors may be displayed such as:

  • 49 (FF05)

  • 49 (FF04)

  • 49 (FF03)

  • 49 (FF02)

  • 49 (FF01)

  • 49 (FFFF)

  • 49 (04FF)

  • 49 (0B0A)

  • 49 (0B22)

  • 49 (0011)

  • 49 (2FD3)

  • 81 Errors

Determining the causes of communication-related issues is a process of elimination. These errors occur when the printer's processor receives a command or data that it does not recognize, causing the processor to stop. The most common causes will be related to the following in some form:

  • A specific software application or settings within the application

  • The Network

  • The printer engine

    NOTE: Before beginning the troubleshooting steps, enter the properties for the PostScript(R) driver. Under the PostScript tab, select PostScript (optimize for portability-ADSC) . Then try printing the same print job that generated the 49 error using these new settings with the PostScript driver.
    NOTE: For Windows NT and 2000, enter the driver properties; click the Advanced tab, then Printing Defaults and finally the Advanced button. The Optimize for portability setting is found in the Postscript Options section.

SOLUTION: Generally, 49 errors are communication errors and can be solved by following the steps in this document.

  1. Turn the printer off, and then turn it on again. If the 49 error clears, proceed to Step 9.

  2. If the 49 error returns turn the power off, unplug the power cable, disconnect all network cables, and remove the HP Jetdirect card, which is located on the formatter, (see Figure 1 for location), or any third-party devices, if installed.

  3. Wait at least 30 seconds before plugging the printer back in directly to a wall outlet. Do not plug the printer into a power strip or a surge protector.

  4. Turn the printer on, using a cold reset. If the 49 error returns, turn the power off, and unplug the printer. Remove the formatter, and check that the parallel I/O board is firmly installed on the formatter board.

    NOTE: To perform a cold reset, turn the printer off, and hold down the GO button while turning the printer back on. Remember to remove the Jetdirect card (if installed) before performing a cold reset. (The Jetdirect card is located on the formatter).

  5. Check for any non-HP memory DIMMs (If any extra memory is installed, remove it). Click here for detailed instructions for installing and configuring memory DIMM.

    NOTE: EDO RAM memory is not supported on HP Color LaserJet 4500 printers and may generate a 49 error if installed.
  6. Reinstall the formatter board.

  7. Reconnect the power cord and turn the power on.

  8. If the 49 error returns, perform a cold reset. (If the 49 error returns, contact HP).If the 49 error clears, turn the printer off, reinstall items removed earlier, and turn printer on. If the error returns, try to isolate which part is causing the problem.

  9. Try to isolate which part is causing the problem by removing and reinstalling the parts that were removed, one part at a time.

  10. If no 49 error occurs at start up, print a configuration page. If there is still no error, try printing from the PC:

    • Print through a parallel port if printing from a network.

    • Print a driver test page to prove proper connectivity between the driver and the printer.

    • Print a small test page from various applications such as Word Pad to prove that specific software applications are functioning properly with the printer.

    • Add graphics to the Word Pad document and print again.

    • Create a new document if the 49 error was generated in a specific software application. Use both the PCL and the PS drivers.

    • Check to see if the printer properties are set to ECP Port if printing through a parallel port. If so, try changing printer port setting to EPP or NORMAL in the computer’s BIOS (refer to your computer manufacturer when changing BIOS settings). Try turning off the High Speed and Advanced Functions in the I/O menu if printing through a parallel port (The I/O menu is accessed through the printer's Control Panel).

    • Rescan any scanned images that generated a 49 error, and try printing again. Change the format of the image to a JPEG file with a lower resolution, or change the image to a different file type such as TIFF or bitmap. Moving the scanned image to the left, right, up, or down the page then resaving the image can also help. Cutting and pasting the document into a new document can help as well.

    • Check the file size by performing a print to file procedure to verify the size of the file spooling to the printer. Reducing the file size can cut down on the occurrence of 49 errors. Performing a print to file procedure verifies the size.

Contact HP?

If the issue is unresolved, click here to contact HP support (http://thenew.hp.com/country/us/eng/contact_us.html) and provide the following information:

  • Document number (bpl07020) used for troubleshooting and a brief problem description to assist HP support in resolving the issue.

  • Can the printer successfully print the internal pages like a Configuration page?

  • Is the 49 error generated on all print jobs or only on specific software applications or print jobs?
