MASTER REMOVAL SECTION
[ 10 - 5 ]
4. Disposed Master Compression Mechanism
1) Initializing
• If the light path on the master compression sensor [B] is open when the power is switched ON or when
everything is reset, the master compression motor operates in the compression direction, and when the light
path to the master compression sensor is blocked, it operates in reverse until the light path is open again.
• If the light path to the master compression sensor [B] is blocked when the power is switched ON or when
everything is reset, the master compression motor operates in the return direction until the light path is open again.
• If the light path to the master compression sensor [B] is blocked when starting master removal, the master
compression motor operates in the return direction until the light path is open. (The initializing operation is
not performed if the light path to the master compression sensor is open when starting master removal.)
2) Master compression
Once the removed master vertical transport operation is complete, the master compression motor
operates in the compression direction to lower the master compression plate [A]. The light path to the
master compression sensor is briefly blocked by the master compression sensor plate [C].
When the light path to the master compression sensor is subsequently opened again, the master
compression motor stops (the stop time can be adjusted using the Test Mode No. 384), and then
operates in the return direction to return the master compression plate to its home position.
3) Ejection of removed master
The master removed by the vertical transport operation is pushed inside the master compression plate [A].
Compression is performed by the master removal motor rotating the master compression plate [A] on the
pivot shaft [D]. The piston shaft link [E] also rotates, but it rotates on the piston shaft [F] rather than on the
pivot shaft [D]. This causes the piston block [G] to move in the direction in which the master ejects out.
