Paper Suction Fans
The printer is equipped with suction fans in the front lower space. The space
behind the Paper Guide L is divided into 3 compartments (Stylus Pro 7400/7800
are divided into 2), and one fan is mounted in each compartment. Paper on the
Paper Guide L1 and L2 is firmly attracted to the guides by air flow created by the
fans. They work to draw air through holes on the sub-platen in the backside of the
paper path. This ensures stable paper feeding. The firmware controls the fan speed
(fan rotation duty control) according to the paper type and printer’s operating
statuses such as setting the paper or during printing.
NOTE:
The number of the fans Stylus Pro 7400/7800: 2 fans
Stylus Pro 9400/9800: 3 fans
