OKI C5250 - 541 Magenta Toner sensor error

Hi Guys,
Customer replaced Magenta toner cart. and since then has got "541 Toner Sensor error" (Magenta). I've swapped whole drum/toner units, removed toner sensor PCB and changed all the optical sensors around (different positions). Error still the same. I haven't got service manual (anyone know where I can get one) so I can't go into the technical side any further.
Can anyone help Please?
