HP LaserJet P4014, P4015, P4515: Firmware Upgrade Issue

Don't Upgrade Firmware with Optional Tray 3 Feeder Installed

There appears to be some sort of bug in the firmware (or the firmware download/upgrade routine), so that if you upgrade the firmware with any accessories attached to the printer, it will no longer power up properly with those accessories attached. In the most common case (printer with an optional tray 3 feeder attached), it will hang in the “Checking Printer” or “Clearing Paper Path” state. If you remove the optional feeder, it will work normally.

To avoid this problem, it is very important to remove all optional accessories (any feeders beyond tray 2, output sorters/stackers, duplexers, envelope feeders, etc.) before doing the upgrade. Once the upgrade is complete, power off and re-install the accessories.

Recovery steps for firmware upgrade issue.

If someone has already upgraded their firmware with accessories attached (be sure to ask them about this if they call with a printer that hangs on power-up), they may be able to recover with the following procedure:

  1. Remove all accessories.
  2. Re-send the firmware upgrade file to the printer (it is important to wait until the upgrade has finished before going to the next step – this may take as long as 30-45 minutes).
  3. When the printer displays that the RFU is finished, power off and then power back on. Once the printer has reached the “READY” state, you can power off again and re-install the accessories.

If the printer now powers up and works normally, all is well. If not, you may have to remove all accessories and add them back one at a time to see which one is causing the problem. In the worst case, an accessory that still causes the printer to hang on power-up may need to be replaced.
