HP LaserJet P4014 and P4015/4515 Printer Series - Error Message "Clearing Paper Path" After Firmware Upgrade Issue After a firmware upgrade, the error message Clearing paper path is displayed on the printer control panel. Solution Perform the following procedure to upgrade the firmware: 1. Remove the additionally installed tray from the printer. 2. Then perform an upgrade. 3. After you have sent the file to the printer, you have to wait at least 30 minutes until the update is completed. (The maximum time experienced was nearly 45 minutes.) The printer will display if the RFU is finished. 4. After that, you have to power off the printer manually and restart the printer but without the trays. After the printer reboot, you will see READY displayed. 5. Power off the printer again, and add paper trays and power on again. Now you have the latest firmware file installed and the printer will not display a Clearing paper path error. If after the firmware upgrade, the message appears again on the printer control panel, we have to remove all the additional accessories installed on the printer and then install them one by one and power cycle the printer. The printer will come to ready mode after all the additional accessories are removed from the printer. After re-installing the accessories (one at a time) and rebooting the printer, we have to check with which accessory the message Clearing paper path occurs and we have to replace that accessory. With the other accessories the printer will come to ready mode.*This Tech Tip is contributed by Laser Pros. u *This Tech Tip is contributed by Laser Pros.
