Hello I am using windows 7 and microsoft word 2013. When i choose to print to the kyocera which has been connected through our server it says document sent to printer. Normally it would ask for a password entry but now it doesnt. At the printer, it says 'Illegal Account press go'. I press go and it is still the same. This is now the same for all computers connected to the printer. I have tried removing the printer and adding again. Can anyone help me with this?
