SYMPTOM
When feeding originals with a different width perpendicular to the feed direction in Mixed
Sizes mode, the second original [A] fed through the ADF is detected as the wrong size [B].
Depending on the combination of sizes (see the chart below), this may cause a customer
to be overcharged.
Note:
 This occurs depending on the value of SP5-131-001 (Paper Size Type Selection).
 This does not occur if the width of the two originals is the same perpendicular to the feed direction
(Example: A3 SEF and A4 LEF).
 The symptom is limited to Mixed Sizes mode.
Value of SP5-131-001 is “0 (DOM/Japan)”
