1) When receiving the pickup preparation signal from the host machine, the following fans are
activated:
• Paper suction fan
• Air separation fan 1
• Air separation fan 2
• Air floatation fan 1
• Air floatation fan 2
• Air floatation fan 3
• Side air floatation fan 1
• Side air floatation fan 2
Each fan operates under a condition according to the paper type and environment.
2) In the case that the coated paper is used and the detection result of the environment
sensor is within the range of the table below, the air pickup heater is turned ON.

is not performed until the air pickup heater reaches a specified temperature.
