Try SIM 63-2 & 4 if you have the test charts (white shading sheet and SIT chart). If you have no charts run SIM 63-5 to set to default values.
Could also try setting scan exposure to color or B/W instead of Auto. I have seen that do some whacky things.

Sounds like a plan! thanks i will try out today.

Happy New Year!!
