3.2. General Descriptions
Following is a brief description of the optional paper feeder board and major electrical component.
3.2.1. General I/O Circuit
The optional paper feeder has the IC2 (16bit I/O Expander) that is controlled by printer engine. The communication protocol of the
printer engine and IC2 is 4-wired serial method.
The IC2 have 16 bit Bi-directional port (D0-D16), and direction of these ports are detected by logic of DI (IC2). When DI’s logic is
low, each port of D01-D16 is output port. When DI’s logic is high, each of D01-D16 is input. When direction of port is input, the
status of D01-D16 is output by IC2 (DO).
When SIO_nCS1 is low, the IC2 is active and then can communicate with printer engine in sync with CLK. The general port (D1-
D16) of IC2 is used for detection of paper size, paper jam and paper existence.

3.2.2. Motor Drive Circuit
The motor (stepping motor) is driven by IC3 (bipolar constant current driver). The motor rotates in sync with the clock (PHASE1,
PHASE2) that is generated by IC4 based on ACF1_SMNA and ACF1_SMNB.
When the both IA1 and IA2 are low level, the motor rotates with maximum current.

3.2.3. Pickup Solenoid Drive Circuit
The pickup solenoid is driven by the transistor (Q1). When the signal nSOL_ON is low, the paper is fed from the tray.
