Here is what happen to my HP Laserjet keeps Initializing (My Model is 1213nf MFP) , After latest update of Firmware to HP Printer it was started
What was noticed is
1. Initially when it starts initializing , the scanner head moves to scan area instead of standby position , on every initialization it moves either left or right . when it back to home position my printer works OK.
2. Another thing was noticed was , if I unplug my network cable my printer works OK.
To avoid initialization what I did was :
Step 1: Unplug network cable , printer usb cable , power cable and wait for 30 seconds.
Step 2: Plug back power cable.
Step 3: Power on the printer and hit Copy And X (Cancel button above copy button) until it says permanent storage initialize.
Step 3:Power on the printer and hit Right Arrrow And X (Cancel button above copy button) until it says permanent storage initialize.
Step 4:Download latest firmware and apply it ( Use USB Cable , DO NOT TRY IT OVER NETWORK TO UPDATE FIRMWARE)
Step 5:If your Router does not support ipv6 : disable ipv6 in your printer (This works in my case.)
Happy Troubleshooting !!
