Detailed Descriptions
Function
Detects B1 width paper.
1) Detects the leading edge of the original and stops the
original feed roller. The user can then manually make the
original straight. 2) Detects the leading and trailing edges
of the original.
Detects the leading edge of the original. This starts the
scanner motor. Also functions as an original width sensor
(it detects A4 or 8.5" width paper).
Detects the leading and trailing edges of the original as it
leaves the scanner unit. Signals a jam if the edges are not
detected.
Detects A3 width paper.
Detects A2 width paper.
Detects A1 width paper.
Detects A0 width paper.
Detects 914mm width paper.
Detects 30" width paper.
Transfers scan image signals from CIS5 LEDs to the SIB
Transfers scan image signals from CIS4 LEDs to the SIB
Transfers scan image signals from CIS3 LEDs to the SIB
Transfers scan image signals from CIS2 LEDs to the SIB
Transfers scan image signals from CIS1 LEDs to the SIB
Direct Realization Edge Scanning Sensor. The DRESS
sensor is mounted on the lower left edge of the carriage
unit. It performs both paper registration and image
registration.
Detects the long encoder strip mounted behind the
horizontal drive belt. Controls the operation of the
horizontal motor, which drives the carriage unit during
printing.
The head lift motor (a stepper motor) rotates an actuator in
and out of the gaps of head lift sensor 1 and 2 to adjust the
size of the gap between the print heads and the paper.

On Carriage Fill Sensor K1. The on-carriage sensor that
monitors the position of the feeler arm on the side of the
K1 ink sub tank. This sensor is used to signal low ink in the
K1 sub tank.
On Carriage Fill Sensor K2 The on-carriage sensor that
monitors the position of the feeler arm on the side of the
K2 ink sub tank. This sensor is used to signal low ink in the
K2 sub tank.
Detects excess air in the K1 ink sub tank of the K1 print
head unit.
Detects excess air in the K2 ink sub tank of the K2 print
head unit.
On Carriage Fill Sensor C. The on-carriage sensor that
monitors the position of the feeler arm on the side of the C
ink sub tank. This sensor is used to signal low ink in the C
sub tank.
On Carriage Fill Sensor Y. The on-carriage sensor that
monitors the position of the feeler arm on the side of the Y
ink sub tank. This sensor is used to signal low ink in the Y
sub tank.
