Are you connected to a PC or a MAC? Is the error displayed on your PC or your printer? Is there a number associated with the error? Please provide the number at the exact error message.
Or, you can go to HP.com/support and drivers and research the error message.

Does it always happen? does it always happen from a particular program? may need to upgrade your memory capacity.

Thank you for the inquiry.
49.4C02 Error The 49.4C02 error usually follows a paper jam. When the customer closes a door after clearing the jammed media from one area of the printer, the control panel immediately posts a 49.4C02 error. Often, the customer will then power cycle the printer and it will hang at Checking Printer. For the 49 error to occur, additional media must still be stuck in the paper path.
Firmware version 5.005.3 contains a fix that allows the printer to recover and notify the customer of the location of the additional jammed media in the paper path. Customers who experience this issue should update to the newer firmware. This version of firmware also fixes the issue with the printer hanging in Checking Printer.
Since a paper jam is the event that triggered the 49 error, if paper jams continue, troubleshoot as necessary.

Hope this helps helps. Please keep us updated and remember to rate this answer.

If the printer gives magenta instead of red you have a problem with one of the other colors. Magenta needs other colors to print red. Print a cofiguration print and check witch color is bad or missing. Replace the cartrridge of the missing/bad color

From the service manual:

An error occurred with the magenta printcartridge drive motor during startup or rotation.

To fix:

1. Check that connectors J5003 on the magenta print-cartridge drive motor and J207 on the DC controller are seated correctly. If they are then:
2. Replace the magenta print-cartridge drive motor. If that doesn't work then:
3. Replace the DC controller.

Some people have issues with the PCL6 driver this causes pcl xl error like this to print. Change your driver from the PCL6 driver to the PCL5 driver. If you don't have the software you can down load it from HP at: http://welcome.hp.com/country/us/en/support.html
