Table 2 shows the signal names for the Print Engine Controller PWB <=> OCT PWB path:
Table 2 Signal Names
Signal Name Description
/OCT PRES Signal from the OCT PWB that detects the installation of the OCT. This
signal turns Low when the OCT is installed.
Signal Levels: High = 3.3V Low = 0V
/NOT FSTK OCT Signal from the OCT PWB generated after the receipt of the signal /NOT
FSTK from the Stack Full Sensor. This signal detects the full of paper on
the Exit Tray of the OCT. Turning High of this signal informs the Print
Engine Controller of the full stack of the Exit Tray.
Signal Levels: High = 3.3V Low = 0V
/OFFSET MOT Motor control signal for the Offset Motor Assembly.
ON
Signal Levels: High = 3.3V Low = 0V
/OCT POWERD Control signal for the OCT. The signal is used to switch on the OCT for
the reason that the OCT Harness Assembly-M includes the signal lines
for the Mail Box and is used commonly for the Mail Box. This signal is
sent from the Print Engine Controller to the OCT PWB when /OCT PRES
is Low.
Signal Levels: High = 3.3V Low = 0V
/OCT MOT ON Motor control signal for the Drive Motor Assembly.
Signal Levels: High = 3.3V Low = 0V
MBX IN/OCT EXIT Signal from the OCT Exit Sensor Assembly. This signal turns High when
the paper actuates the OCT Exit Sensor Assembly.
Signal Levels: High = 3.3V Low = 0V
DIRECT SOL ON Control signal for the Direction Solenoid. This signal is High when the
Direction Solenoid is actuated.
Signal Levels: High = 3.3V Low = 0V
/NOT FSTK OCT Signal from the Stack Full Sensor. This signal turns High continuously
when the Exit Tray becomes to be full of paper.

Signal Name Description
/NOT FSTK Signal from the Stack Full Sensor that detects the installation of the OCT.
This signal turns Low when the OCT is installed.
Signal Levels: High = 3.3V Low = 0V
/OCT HOME Signal from the OCT Home Sensor. This signal detects the home position
of the Offset Roll Assembly. Turning Low of this signal informs the OCT
PWB that the initiation of the Offset Roll Assembly is completed.
Signal Levels: High = 3.3V Low = 0V
