4F Error : The head drive voltage has dropped from the high to low level in anabnormally short period.
1. Replace Head/Carriage Unit, Part # LK3211001 https://ebay.to/328Ko1y
2. Replace Main PCB, Part # LT1067001 https://ebay.to/2zlOgQD
Not worth to fix since the print-head + labor from service center cost more than a new printer.
4F indicates printhead problem - either to replace the print head or the print head PCB.
