1. Color reproduction when copying cloth
【 Symptom 】
When copying cloth as an original, the printed color becomes reddish.
【 Cause 】
This symptom occurs when a specific cloth is used.
When a specific type of cloth that reflects infrared rays is used, the infrared area will be read as
more reddish than the original.
【 Countermeasure 】
There is no countermeasure on this series.
In order to improve this symptom, it is necessary to change the lens to a type that has the ability
to cut the infrared rays. The parameter of the image processing also needs to be modified.

7. Gradation Adjustment (1/2)
【 Symptom 】
FEET (rear edge side) of gradation adjustment output looks abnormal. It is different with
color tone or gradation adjustment.
【 Cause 】
FEET gradation adjustment is the image processing mainly applied to the edge parts of letters. It is
comparably difficult to converge the targeted gradation as this mode has less gradation steps. So this
image is specification.
【 Action in the field 】
Basically you do not need to worry about the convergence value for the gradation adjustment of
FEET. However, if the gradation adjustment falls a long way outside of the following range, you
must conduct a gradation adjustment again after performing “Initialization and Stabilization”.
Convergence at high density part within +/- 100
Convergence at low density part within +/- 60
