The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

■ Initial Document Size DetectionThe document length sensor 1 (SR7) and document length sensor 2 (SR10) detect the longitudinal size of the document placed on the document tray, and the document width volume (VR1) and A4R/LTRR identification sensor (SR8) detect the lateral size of the document.When a document is placed on the document tray, detection levers of the two document length sensors move the light shielding plate to prevent light from passing through the photo interrupter.If the slide guide is adjusted to the document size, the resistance of the document width volume mounted inside the document tray changes to detect the document size.Document sizes are determined by the combination of the ON/OFF states of document length sensors, the combination of ON/OFF states of document width volume, and the combination of ON/OFF states of A4R/LTRR identification sensor.

Document Pickup/Separation ■ Basic Pickup Operation
With a document placed on the document tray, pressing the print start key will pick up the document in the following manner.
Pickup operationWhen the pickup/feed motor (M1) turns in reverse direction, the pickup roller unit lowers to rotate the pickup rollers, thus feeding the document. The stopper rises in conjunction with the pickup roller unit. The separation sheet and pad are used to prevent multiple sheets from being fed together.

Formation of loopWhile the pickup/feed motor (M1) is turning in the reverse direction, the document is fed against the stationary registration roller to form a loop because the registration clutch is not driven, thus preventing the document from skewing.

FeedThe pickup/feed motor (M1) turns in the reverse direction to drive the registration clutch (CL2), thus allowing the registration roller to feed the document. The read roller feeds the document to the read wait point. When the document reaches the read wait point, the pickup/feed motor (M1) stops.

Stream readingWhen the leading edge of the document reaches the reading point, an image leading edge signal is sent to the host machine to start stream reading. "Stream reading" is a scan mode in which a document is moved on the optical system's glass using the platen roller.The read image is stored in the memory of the host machine.

■ Pickup Unit and StopperThe pickup unit consists of a pickup roller and feed roller. When the print start key is pressed or a document pickup signal is input, the pickup/feed motor (M1) turns in the reverse direction to lower the pickup unit via the pickup clutch (CL1), turning the pickup roller and feed roller to feed the document. The stopper rises in conjunction with the pickup roller unit. When the document is picked up, the separation pad and separation plate prevent multiple sheets from being fed together.When the document is fed to the registration roller to be looped, the registration clutch (CL2) operates and the power of the pickup/feed motor is transmitted to the registration roller to feed the document.

Document Reversing
■ Basic OperationThere are two types of document reversal operation: one that is performed from the top to the reverse side of the document and the other that is performed from the reverse side to the top of the document. Since the basic operation methods are identical, only the reversal operation performed from the reverse side to the top is discussed below.
Top side pickupThe pickup/feed motor (M1) drives the read roller 1 and platen roller to scan the surface of the document. After completion of scanning, the read roller 2 and delivery reversal roller feed the document to the delivery unit.

Reversal/feed 1When the trailing edge of the fed document moves past the delivery reversal sensor (SR3), the pickup/feed motor stops. Immediately after this, the pickup/feed motor starts turning in the reverse direction to feed the document to the registration roller, then it stops. At this time, the pressurization solenoid (SL2) turns on to release the delivery reversal roller.

Reversal/feed 2The pickup/feed motor turns to feed the document to the reading wait point and stops.Thus, the document has been reversed. Next, the document is picked up again and its reverse side is read, turning off the pressurization solenoid. After this, thedocument is reversed again, fed, and then delivered.

Document Feeding/Delivery ■ Basic Operation
After completion of stream reading on the document glass, the document is delivered to the document delivery unit as discussed below.
Document feed/delivery After moving past the reading position, the document is fed by the read roller 2 and delivery reversal roller driven by the pickup/feed motor (M1) which is turning in the reverse direction. The delivery reversal roller is normally pressurized; the Shift solenoid (SL2) turns on only when the document is reversed for duplex printing.
