1.This chapter describes the objective and role of each function, the relationship between the electri-
cal and mechanical systems and also gives an overview of the operation timing of each part by func-
tion.
The symbol in the outline diagram indicates the transmission of mechanical drive, and the
symbol together with a signal name indicates the flow of electric signals.
2.In the descriptions of the digital circuits of the cassette feeding unit, “1”indicates a high electric sig-
nal level and “0”indicates a low electric signal level.
The cassette feeding unit incorporates microprocessors, but as their internal operation cannot be
checked, a description of microprocessor operation has been omitted.
Since it is assumed that service engineers will not repair printed circuit boards on the customers’
premises, descriptions of printed circuit boards are limited to overviews illustrated with block dia-
grams.Consequently, circuit descriptions cover from sensors to the input sections of the major print-
ed circuit boards and from the output sections of the major printed circuit boards to the loads, as well
as block diagrams of each function.

I. BASIC CONFIGURATION
A. Overview
The unit transports the paper to the printer assembly.
The operation sequence of the unit is controlled by the paper deck driver PCB. This
PCB incorporates an 8-bit microprocessor (IC201) that performs operation sequence
control and control of serial communications with the option controller PCB.
The paper deck driver PCB drives solenoids, motors, etc. in response to commands
transmitted from the option controller PCB, via serial communication lines. The paper
deck driver PCB also notifies the option controller PCB of sensor and switch information,
via the serial communication lines.

II. PAPER FEED AND DELIVERY SYSTEM
A. Overview
The paper deck driver PCB starts the paper feed operation when it receives the paper
feed command from the option controller PCB. Paper fed by the Pick up roller is trans-
ported to the feeder assembly by Pick up/feeding roller and the separation roller.The reg-
istration roller corrects any skew feed in the paper and then stops.
The paper deck driver PCB causes the paper feed motor (SPM3) to rotate.This caus-
es the Pick up roller, Pick up/Feedig roller and the separation roller to turn.
At the same time, after the paper deck driver PCB causes the motor (SPM1) to rotate,
the paper feed solenoid (SL1) is turned on. This lowers the Pick up roller to the surface
of the paper. As a result, the rotating Pick up roller feeds the paper to the feeder assem-
bly. The paper transported to the feeder assembly goes through the registration paper
sensor (PS1) and stops temporarily when it reaches the registration roller. When the
paper deck driver PCB subsequently receives the paper feed command it causes the
paper feed motor (SPM3) and the delivery motor (SPM2) to turn. At the same time, the
registration roller clutch (CL1) is turned on.This causes Pick up/feeding roller, the regis-
tration roller and delivery roller 2 to turn, and the paper is fed to the printer assembly.
There are two photo-interrupters (PS1 and PS2) in the delivery path that detect when
the paper reaches the path, and when it goes through it.
The paper deck driver PCB assembly assumes that a paper jam has occurred when
the paper does not reach or pass the sensors (in the paper feed path) within a specified
time. It then stops operation and notifies the option controller PCB that a paper jam has
occurred.
