Ask customer kung ano history,
hint: may foot prints ng daga.

paper LED light indicator is blinking
check wires and found cut wires, after ko mareconnect mga putol ng wires ng dynamo/motor.

next error: all lights are blinking pag on pa lng ng power.
Check waste ink counter using resetter 100% na kaya nereset ko.
After ko mareset, same error parin.
Bunot lahat ng wires connected sa main board at same error parin.

kaya sa main board na ako nag focus at using multi tester.
Nakita ko "F1" label sa board, open ang fuse.

next step na ginawa ko, gumamit ako ng hotair para maalis ang SMD Fuse.
After maalis ay jumper n lang gamit ang soldering iron at lead.

at whhaallaaa solved ang problem.
