Printers: HP LaserJet P4014, P4015, P4515 Problem: Printers cycling engine repeatedly and/or 41.8 error message. Fix: Replace fuser Due to an issue with earlier firmware versions the P4010 series printers are known to exhibit prolonged cycling of the print engine during, or at initial printing. This issue, in rare cases, has also been accompanied with a 41.8 error code which is not listed in the manual. This error is caused by an electronic disturbance in the fuser which triggers a mis-feed in the printer.   *This Tech Tip is contributed by Laser Pros.
