Hello,
I replaced a defective formatter board in an HP P4014n but failed to reset the NVRAM. Now the printer thinks it is a HP P4515. I updated the firmware via FTP to 20030510 04.191.1 (the latest I could find for the 4014) but the issue is not resolved. Now I am periodically getting 49.4C02 errors that force me to power cycle the printer. Is there a way to reprogram the unit to the proper model? Thanks in advance for any assistance.
