If the light toggles between Green and Orange 4 times, this would indicate a Purge sensor error (5C00 on screen)
If it blinks 4 times between green flashes this will indicate a No Ink error (1600 on your screen;
1601- No ink Black: 1611-No ink Yellow:
1612-No ink Magenta: 1613-No ink Cyan.
If these tanks are full then the ink sensor is having trouble seeing the ink remaining or is defective.

The Purge unit (QG4-0257-000) is $28.81 plus the cost of labor to install. Is it ecconomical to repair this unit or purchase a replacement?

Thanks for all your help Barry I will try to source a quote here in the uk for the purge unit and repair. Then decide if its economical to repair.

Does anyone know how easy it is to replace the purge sensor with a new purge unit (Q64-0257-000)??? Should I even try? FYI, I've never fixed a printer before but am fairly mechanically inclined.
