    Context sd one scanner 24 inch pale blue background

    Hi fellow technician,
    I have a context sd one scanner which when i scan documents it gives a pale blue background in entire sheet. I've checked glass and cleaned it. The power supply which is adaptor also have been changed . But nothing happens. The only thing that comes to my mind is to calibrate the scanner but sadly i do not have calibration sheet. I have access to canon canada site. But sadly i couldn't find any sheet in pdf format because it is obsolote.
    Can somebody help me with this issue?
    Can somebody send me a scan of calibration sheet?
    Or at least can somebody tell me possibility of being same calibration sheet with new scanner generation?
Working...
