6 DESCRIPTION OF MODES
6-1. Mixed Original Mode
•
The copier detects the size of each page of the document as it is taken up and fed in and, according to the size detected, feeds the copy paper of the corresponding size selected from among the available paper sources.
•
The mode is mainly used when making copies from a document set consisting of pages of different sizes.
6-2. 1-Sided Mode
•
When a multi-page document is being copied, the copier detects the size of only the first page of the document and copies the subsequent pages based on that size detection.
•
This saves the copier the time required f or detecti ng the sizes of the subsequent pages of the document, making for a faster and more efficient paper feed timing.
Note:
If a document of pages of varying sizes is used in this mode, image trouble could result including missing copy image. (The system does not, however, force a misfeed condition.)
6-3. 2-Sided Mode
•
The copier automatically turns over 2-sided originals for a speedy copying operation (copies are made in the order of the first and second pages).
6-4. Single Feed Mode
•
This mode may be used when the user wants to make copies from an original for which feeding is not guaranteed (pasted-up sheet, translucent paper, heat-sensitive paper, etc.).
•
When a single original is inserted into the Single Feed Tray, the ADF automatically takes it up and feeds it in to let the copier run a single copy cycle.
•
Each original is transported at a low speed.

•
The document pick-up mechanism consists of the Document Stoppers and Pick-Up Rolls.
•
The Document Stoppers determine the leading edge position of the document loaded in the ADF. They are in the lowered position when in their standby position and raised when a document take-up sequence is started.
•
The Pick-Up Rolls are in the raised position in their standby state and lowered when a document take-up sequence is started, pressing the document set downward during the sequence with the tension of the Document Pressure Springs.
•
The operation of the Document Stoppers and Pick-Up Rolls is controlled by Pick-Up Motor, Pick-Up Sensor, and a cam.

The Pick-Up Rolls and Take-Up Rolls turn to transport the document loaded in the Docu­ment Feed Tray up to the Registration Roller.
•
The Single Feed Roller, on the other hand, turns to transport the document placed in the Single Feed Tray.
•
The Pick-Up Rolls, Take-Up Rolls, and Single Feed Roller are driven by Take-Up Motor. To drive the Single Feed Roller, Take-Up Motor is turned backward, at which time the Take-Up Roll Shaft also turns backward. Because of the functioning of the one-way pul­ley, however, the backward rotation of the shaft is not transmitted to the Pick-Up Rolls or Take-Up Rolls.
•
The Front Separator Pads and Separator Pads together function to prevent double feed when two or more pages of a document set are taken up.

10 MISCELLANEOUS
10-1. Document Size Detection Mechanism
•
The document size is determined by means of two different systems of document width detection and document length detection.
Document Width Detection
•
The width of an original is detected by the combination of the blocked (L) and unblocked (H) states of Width Sensors 1 PC5, 2 PC6, and 3 PC7, as detected while the original is being taken up.
•
Each sensor is located as follows with reference to the Document Edge Guide in the rear . PC5: 236.5 mm; PC6: 268 mm; PC7: 288 mm
Document Length Detection
•
The length of an original is detected by counting the number of pulses generated by Main Drive Motor for the period of time from when the Registration Roller starts turning to when the trailing edge of the original moves past Registration Sensor.
•
In the Single Feed mode, the period of time for counting the number of pulses is up to when the trailing edge of the original moves past Single Feed Empty Sensor.
10-2. 15° Open Detection Mechanism
•
To enable the copier to detect the document size when the ADF is used as the Original Cover of the copier , there is the Lever Actuator provided in the ADF body.
•
The Lever Actuator mov es the Original Cover Detecting Lever mounted on the copier.
10-3. Raised/Lowered Position Detection Mechanism
•
There is a magnet installed in the ADF body to allow the copier to know that the ADF is raised or lowered.
•
This magnet actuates the Size Reset Switch on the copier.

4. Raise and lower the ADF.
5. Load a document set in the Document Feed T ray.
6. Press S1 once.
7. This starts the paper passage check.
✽
To interrupt a continuous paper passage mode (S2-4: OFF), press S1 once . I f S1 is then pressed a second time, the ADF feeds all originals out of itself to terminate the paper passage mode.
✽
In an intermittent paper passage mode (S2-4: ON), each press of S1 lets the ADF feed an original through itself.
✽
To select either the continuous or intermittent mode, turn OFF the Power Switch of the copier, flip S2-4 to OFF and then ON, and turn ON the Power Switch.

DIS/REASSEMBLY,
ADJUSTMENT
Precautions for Disassembly, Reassembly, and Adjustment
1. Before attempting to disassemble the ADF, always make sure that no power is being supplied from the copier.
2. While power is being supplied to the ADF, do not attempt to remove/install the print jacks from/to the PWBs or unplug/plug in the connectors.
3. If the ADF is run with its covers removed, use care not to allow your clothing to be caught in the belt or other moving parts.
4. The basic rule is do not run the ADF with any of its parts removed.
5. A toothed washer is used with the screw that secures the ground wire to ensure positive conduction. Do not forget to use this washer at reassembly.
6. To reassemble the ADF, reverse the order of disassembly unless otherwise specified.
7. Do not attempt to remove or loosen the screws to which red paint has been applied.
Purpose of Application of Red Paint
Red paint is applied to the screws of parts that cannot be readjusted, set, or reinstalled in the field.

TROUBLESHOOTING
General Precautions
1. When servicing the ADF with its covers removed, use utmost care to prevent your hands, clothing and tools from being caught in moving parts.
2. Before attempting to replace parts and unplugging connectors, make sure that no power is being supplied from the copier.
3. When creating a closed circuit and measuring a voltage across connector pins speci­fied in the text, be sure to use the green wire (GND).
4. Keep all disassembled parts in good order and keep tools under control so that none will be lost or damaged.
Reading the Text
1. If a component on a PWB or any other functional unit including a motor is defective, the text only instructs you to replace the whole PWB or functional unit and does not give troubleshooting procedure applicable within the defective unit.
2. The text assumes that there are no breaks and shorts in the harnesses and all connec­tors are plugged into the right positions.
