1-1. Head Maintenance Mechanism

The maintenance unit (also called as Ink Pan) is equipped with a wiper to clean the print head nozzle surface.
The wiper comes into contact with the head holder by means of raising and lowering the belt platen. To keep the
maintenance unit out of the way of the belt platen during printing, the maintenance unit is stored on the right-hand
side of the machine.
During maintenance (head cleaning), it operates directly under the print heads.
Actions from printing to maintenance
1) The belt platen moves from the printing position to the lower limit position.
2) The Maintenance unit moves toward the operation position.
3) The Maintenance unit arm activates the operation position sensor.
