54
ID sensor
coefficient (K5)
maximum/
minimum error When the K5 is more
than the value of
SP3-362-003 or less
than the value of
SP3-362-004, the error
54 is displayed. • ID sensor pattern density is too high or low.
• ID sensor or shutter is defective.
Same as 53
55
Gamma error:
Maximum Gamma is out of range.
5.0 < Gamma • ID sensor pattern density is too high.
