INTRODUCTION
The following rules apply throughout this document:As a rule, the descriptions in this documentation are based on the following:1. As needed, the work of each function and its relationship with electrical and me-
chanical parts are explained; where applicable, the timing at which associated partsare driven are also outlined.In a diagram, the symbol indicates a path of mechanical drive; the symbol
accompanied by a notation indicates the flow of an electrical signal.The expression “power-on” means turning on the power switch, closing the frontdoor, and closing the delivery door so that the parts of the machine are supplied withpower.
2. In a digital circuit, the state of a signal is indicated by ‘1’ if its voltage level is highand by ‘0’ if low. The level of voltage, however, differs from circuit to circuit.The machine uses a CPU; however, since the internal functions of a CPU is outsidethe scope of a service person, detailed explanations are omitted from descriptions. Inthis document, a circuit diagram may cover from sensors to inputs of a controllerPCB or from outputs of a controller PCB to loads, or it may be a functional diagram.
The descriptions of the machine are subject to change for product improvement, and ma-jor changes will be communicated in the form of Service Information bulletins.
All service persons are expected to be fully familiar with the contents of this ServiceManual and Service Information bulletins to develop a good understanding of the machine,equipping themselves with the ability and skill to identify faults and to maintain the machinein good order.

2.3.2 Detecting the Presence/Absence of an OriginalThe presence/absence of an original on the original tray is checked by the original set sen-
sor (PI5).When an original is placed on the original tray, the detecting lever operates in conjunction
with the light-blocking plate, which blocks the light of the photointerrupter, causing theoriginal set sensor (PI5) to generate the original detection signal (DTS). The ADF controllerPCB turns on the Original Set indicator in response to the original detection signal (DTS).

2.3.3 Initial Original Size Detection (feed direction)The initial original size detection (feed direction) mechanism is executed using the large/
small identification sensor (PI3) designed to find out whether the original on the originaltray is of a small size or a large size. In addition, it serves to distinguish between LTRR andLGL during last original size detection.
When a large-size original is placed on the original tray, the detecting lever operates inconjunction with the light-blocking plate, which blocks the light of the photointerrupter,causing the machine to identify the original as being of a large-size and send the result ofdetection to its host machine.
The result is based on real-time detection, and is sent to the host machine at 100-msec in-tervals.

2.3.4 Initial Original Size Detection (breadthwise)a.Outline
The initial original size detection mechanism for the breadthwise direction of an originalis performed by the original width detecting volume (VR1) located inside the original tray.
The original width volume operates in conjunction with the slide guide, and the resis-tance shows analog fluctuations. The ADF controller receives the fluctuations in resistancein the form of the original size signal (WIDTH), and converts it to a breadthwise size.
The A4R/LTRR identification sensor (PI4) is used exclusively to enable the originalwidth detecting volume (VR1) to accurately detect the width of A4R (210 mm wide) andLTRR (216 mm wide).
The A4R/LTRR identification sensor generates the A4R/LR identification signal (‘1’)when the width of an original is 197 mm or more and less than 214 mm.

2.3.5 Last Original Size DetectionThe last original size detection mechanism is executed by the post-separation sensor (S3).The last original size detection mechanism takes place when the original is held in read
wait position. The mechanism uses the width detected by the initial original size detectionmechanism using the original width volume (VR1), and uses the post-separation sensor (S3)to find out the length of the original.
If the original is large size, the post-separation sensor (S3) emits light in response to thereference intensity adjustment signal (SEPAJ), and its light-receiving segment detects thelight reflected by the original, and sends the original detection signal (P-SEP) to the ADFcontroller PCB.

2.3.6 Checking Originals When Printing Originals of Different Widths or inExtra-Length Mode
When printing originals of different widths or in extra-length mode, the originals are iden-tified as being large size or small size with reference to the state of the post-separation sen-sor (S3) with an original held in read wait position. The detection is based solely on thelength of the original, and is executed within the feed path.
a.Post-Separation Sensor (S3) Is Off (small size)The distance over which the original has moved is checked based on the number of
clock pulses from the feed motor (M2) between when the post-separation sensor turns off(passage of the trailing edge) and when the original is held in wait position.
b. Post-Separation Sensor (S3) Is On (large size)The distance of feed is detected based on the number of clock pulses from the feed mo-
tor (M2) between when the read sensor (S2) turns on and the read sensor (S2) turns off.

When the Start key is pressed while originals are placed on the original tray, the followingtakes place to pickup up the originals:
a.PickupThe pickup motor (M1) rotates in reverse, and the pickup clutch (CL1) turns on. As a
result, the stopper and the pickup roller unit move down to rotate the pickup roller. Theseparation plate and the separation pad are used to prevent double-feeding of originals.
F02-204-01
b. ArchingThe pickup motor (M1) is stopped so that the original is butted against the registration
roller and is made to arch, thereby removing any skew.

2.5 Reversal2.5.1 Operations
The reversal mechanism operates to turn over originals from their first side to their secondside or from their first side to their second side; these two operations are virtually identical,and the discussions that follow are based on turning originals from their first side to theirsecond side.
a.Picking Up the 1st SideThe feed roller rotates using the drive of the feed motor (M2), and the 1st side is read.
To move the original, the delivery reversing roller rotates using the drive of the deliveryreversal motor (M3), and the original is moved to the delivery assembly.
The locking solenoid (SL2) turns on in reference to the end of reading operation, and thedelivery reversing roller becomes locked to let the original move.
F02-205-01
b. Reversal/Feed 1When the trailing edge of the original moves past the delivery reversal sensor (S1), the
delivery reversal motor (M3) stops. Immediately thereafter, it starts to rotate in reverse tomove the original to the registration roller 2.

3 Jam
The machine uses the sensors shown in F02-301-03 to check for an original jam. TheADF controller PCB detects a jam in relation to the presence/absence of an original over aspecific sensor at such times as stored in its ROM in advance.
When a jam is detected, the machine sends the data to its host machine in the form of acode:
A jam occurring in the machine is indicated by the following two ways:• Host machine’s service mode screen• LEDs on the ADF controller PCBService Mode Screen of the Host Machine

4 Power Supply
The following figure shows an outline of the machine’s power supply system.The machine’s power supply receives two type of 24V power (24 VP, 24 VL) from its host
machine.The 24VP supply is mostly used for loads, and is cut off when the upper cover is opened.If an overcurrent starts to flow into the circuit, the circuit breaker (CB1) will turn on to
cut the power supply, thereby protecting the circuit.The 24VL supply is converted to 5V power by the IC11, and is sent to sensors and is also
used to drive the controller PCB.
