2.Detailed Descriptions
The up and down movement of the decurl unit is controlled by two sensors.
•
Before a print job, the decurl unit HP sensor [1] detects the home position of the decurl unit.
•
To correct front curl (concave) , the unit is raised [A] the distance specified by the user. If the decurl unit limit sensor
[2] detects the bottom actuator, this triggers the over limit error (SC582).
•
To correct back curl (convex), the unit is lowered [B] the distance specified by the user. If the decurl unit limit sensor
[3] detects the top actuator, this triggers the over limit error (SC582).
Moving the decurl roller up or down changes the amount of pressure applied to the paper to correct paper curl. The
maximum range of the decurl unit movement is ±13.15 mm from the home position of the decurl unit.
The amount of pressure applied to correct paper curl can be adjusted with the "Adjustment Settings for Skilled
Operators".

•
The next screen presents options for adjusting the amount of curl applied (Weak or Strong) for all the trays
(Tray 1 to 12).
•
To adjust the amount of pressure applied for "Weak" or "Strong", use SP1906-1 to 12.
