Page 359 PAPER FEED AND SEPARATION MECHANISM 2. DETAILED DESCRIPTIONS 2.1 PAPER FEED AND SEPARATION MECHANISM B390D104.WMF The paper tray holds 500 sheets. The paper feed roller [A] drives the top sheet of paper from the paper tray to the copier/printer. The friction pad [B] allows only one sheet to feed at a time.
Page 360 PAPER LIFT MECHANISM 2.2 PAPER LIFT MECHANISM B390D106.WMF B390D107.WMF The paper size switch detects when the tray is pushed in. When the paper tray is pushed into the machine, the pin [A] for the lift motor pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom plate lift shaft in the tray engages the bottom plate pressure lever coupling [D].
Page 361 PAPER LIFT MECHANISM The paper size thresholds for this feature depend on SP1-908-8, 9, 17, and 18. (Note that there are two paper size thresholds for each tray: small and middle. Some models only use the small threshold.) The amount of reverse depends on SP 1-908-1, 2, 3, 10, 11, and 12.
Page 362 PAPER END DETECTION 2.3 PAPER END DETECTION B390D105.WMF If there is some paper in the paper tray, the paper stack raises the paper end feeler [A] and the paper end sensor [B] is deactivated. When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom plate and the paper end sensor is activated.
Page 363 PAPER HEIGHT DETECTION 2.4 PAPER HEIGHT DETECTION B390D107.WMF The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. When the amount of paper decreases, the bottom plate pressure lever [C] moves the actuator up.
Page 364 PAPER HEIGHT DETECTION The amount of remaining paper depends on SP modes 1-908-6, 7, 15, and 16. The amount of forward rotation depends on SP1-908-4, 5, 13, and 14. Note that there are two paper size thresholds for each tray: small and middle (this is the same as for the paper lift mechanism described earlier).

Page 383 REVERSE ROLLER AND PICK-UP ROLLER RELEASE 2.2 REVERSE ROLLER AND PICK-UP ROLLER RELEASE B391D107.WMF B391D108.WMF To prevent the paper from being torn when pulling out the paper feed tray, the reverse and pickup rollers are set so that they release automatically. When the paper tray [A] is not inside the machine, the reverse roller [B] is away from the paper feed roller [C] and the pick-up roller [D] stays in the upper position.
Page 384 TRAY LIFT 2.3 TRAY LIFT B391D110.WMF When the paper feed tray is put in the machine, the tray switch [A] on the back face turns on and the tray lift motor [B] starts up. The base plate lift shaft [C] is coupled to the lift motor at shaft [D], so the base plate of the tray is lifted.
Page 385 NEAR END/END DETECTION 2.4 NEAR END/END DETECTION This tray can hold two stacks of paper, so the machine needs to monitor the status of both these stacks. There are seven sensors to do this. In the right tray (paper feed side), three height sensors measure the height of the stack, and an end sensor detects when all the paper is used up.
Page 386 RIGHT TRAY SIDE FENCE 2.5 RIGHT TRAY SIDE FENCE B391D109.WMF When the paper in the right tray is used up, the side fence solenoid [F] activates and stays on until the side fence open/closed sensor [E] detects that the fence is open.
Page 387 RIGHT TRAY PAPER END DETECTION 2.7 RIGHT TRAY PAPER END DETECTION B391D106.WMF B391D111.WMF The paper end sensor [A] detects when copy paper in the right tray runs out. When there is paper in the tray, the paper pushes up the paper end feeler [B] and causes the actuator to come between the LED and photo diode of the sensor.

Page 408 MIXED ORIGINAL SIZE MODE 2.2 MIXED ORIGINAL SIZE MODE This section explains what happens when the user selects mixed original size mode. Because this ADF is a sheet-through document feeder, the method for original document width detection is the same as when the originals are the same size, but the document length detection method is different.
Page 409 PICK-UP AND SEPARATION 2.3 PICK-UP AND SEPARATION B386D504.WMF B386D505.WMF The original is set with the image facing up. The original pushes actuator [A] and the original set sensor [E] is activated. After pressing the start button, the pick-up solenoid [D] is activated and the lift plate [C] lifts the original up until it comes in contact with the pick-up roller [B].
Page 410 ORIGINAL TRANSPORT AND EXIT 2.4 ORIGINAL TRANSPORT AND EXIT 2.4.1 SINGLE-SIDED ORIGINALS B386D506.WMF The DF feed motor feeds the separated original to the first transport roller [A] at maximum speed. When the registration sensor [B] detects the leading edge, the motor stops for a short while.
Page 411 ORIGINAL TRANSPORT AND EXIT 2.4.2 DOUBLE-SIDED ORIGINALS B386D204.WMF B386D205.WMF When the registration sensor [B] detects the leading edge of the original, the DF feed motor (which drives the feed roller) and transport motor (which drives the transport roller) both switch off. After a brief interval, the transport motor alone reactivates to drive the first [A] and second transport roller [G] and the exit roller [F].
Page 412 ORIGINAL TRANSPORT AND EXIT B386D206.WMF B386D207.WMF The original is then sent to the reverse table [H] a second time to be turned over. This is done so that the duplex copies will be properly stacked front side down in the exit tray [J] in the correct order. 2.4.3 ORIGINAL TRAILING EDGE SENSOR During one-to-one copying, copy paper is fed to the registration roller in advance (while the original is still being scanned), to increase the copy speed.
Page 413 STAMP 2.5 STAMP B386D507.WMF This function is only for fax mode. There is a stamp [A] between the 2nd transport roller [B] and the exit roller [C], and its solenoid is controlled by the copier directly. When the original reaches the stamp position, the DF feed motor stops. At 300 milliseconds after stopping the DF feed motor, the stamp solenoid turns on if the page was sent successfully (immediate transmission) or stored successfully (memory transmission).

Page 508 JUNCTION GATES 4.5 JUNCTION GATES B408D108.WMF Depending on the finishing mode, the copies are directed up, straight through, or down by the combination of the tray junction gate [A] and stapler junction gate [B]. These gates are controlled by the tray junction gate solenoid [C] and stapler junction gate solenoid [D].
Page 509 UPPER TRAY 4.6 UPPER TRAY B408D109.WMF When the paper limit sensor [A] switches on during feed-out for each of three consecutive sheets of paper, paper overflow is detected. B408 17-18...
Page 510 LOWER TRAY UP/DOWN MECHANISMS 4.7 LOWER TRAY UP/DOWN MECHANISMS B408D112.WMF The vertical position of the lower tray [A] depends on the height of the copied paper stack on the lower tray. The stack height sensor feeler [B] contacts the top of the stack, and the lower tray lift motor [C] controls the tray height.
Page 511 PAPER SHIFT MECHANISM 4.8 PAPER SHIFT MECHANISM B408D110.WMF In the sort/stack mode, the shift roller [A] moves from side to side to separate the sets of copies. The horizontal position of the shift roller is controlled by the shift motor [B] and the shift gear disk [C].
Page 512 JOGGER UNIT PAPER POSITIONING MECHANISM 4.9 JOGGER UNIT PAPER POSITIONING MECHANISM B408D114.WMF B408D113.WMF In staple mode, each sheet of copy paper is vertically and horizontally aligned when it arrives in the jogger unit. For the vertical paper alignment, the positioning roller solenoid [A] turns on shortly after the stapler tray entrance sensor [B] turns off, and the positioning roller [C] pushes the copy against the bottom of the stack stopper [D].
Page 513 EXIT GUIDE PLATE 4.10 EXIT GUIDE PLATE [B] [C] B408D111.WMF When stacking a large size of paper (such as A3, DLT) in the jogger unit, the leading edge of the paper reaches the exit rollers. To prevent the paper from running into the exit rollers and not being aligned correctly, the exit guide plate [A] is moved up to make a gap between the exit rollers.
Page 514 STAPLER MECHANISM 4.11 STAPLER MECHANISM B408D116.WMF The staple hammer motor [A] drives the staple hammer. The staple sheet sensor [B] detects the leading edge of the staple sheet at the stapling position to prevent the hammer from operating if there are no staples at the stapling position.
Page 515 STAPLER UNIT MOVEMENT MECHANISM 4.12 STAPLER UNIT MOVEMENT MECHANISM B408D117.WMF The stapler motor moves the stapler [A] from side to side. After the start key is pressed, the stapler moves from its home position to the stapling position. If two-staple-position mode is selected, the stapler moves to the front stapling position first, then moves to the rear stapling position.
Page 516 PAPER FEED-OUT MECHANISM 4.13 PAPER FEED-OUT MECHANISM B408D118.WMF After the copies have been stapled, the stack feed-out motor [A] starts. The pawl [B] on the stack feed-out belt [C] transports the set of stapled copies up and feeds it to the shift roller. The shift roller takes over stack feed-out after the leading edge reaches this roller.

Page 533 DETAILED SECTION DESCRIPTIONS 2.2 DETAILED SECTION DESCRIPTIONS 2.2.1 OUTPUT TRAY MECHANISM Stack height detection B442D104.WMF Stack height detection lever [A]: Driven by stack height lever solenoid [B]. Two sensors detect the height of the stack in the output tray: the stack height [C] and lever [D] sensors.
Page 534 DETAILED SECTION DESCRIPTIONS Output tray up/down mechanism B442D105.WMF Overview The output tray motor [A] lifts/lowers the tray if the stack height is not at the target position. Gears [B] and [C] keep the angle of the tray constant at any tray position. Output Tray Downward Movement The top of the paper stack is checked after every page (or set of pages) has been fed out.
Page 535 DETAILED SECTION DESCRIPTIONS 2.2.2 PAPER FEED Overview The following paper feed out modes can be selected at the printer driver. Mode Description Straight feed out mode Paper is fed directly to the output tray without shifting or stapling. Shift sorting mode Alternate sets are shifted before being fed to the output tray.
Page 536 DETAILED SECTION DESCRIPTIONS Shift sorting mode B442D111.WMF B442D113.WMF At the start of the job, and for odd numbered sets of copies, the mechanism is the same as the straight feed out mode. However, even numbered sets are fed back to the jogger tray, which shifts the sets to one side before feeding them out.
Page 537 DETAILED SECTION DESCRIPTIONS B442D107.WMF After the paper reaches the end fence [A], the jogger fence [B] shifts the paper across. The jogger motor [C] drives the jogger fence. The home position sensor [D] detects when the jogger fence has returned to home position. When the next set begins, the paper exit unit moves down, and the machine operates the same way as straight feed out mode.
Page 538 DETAILED SECTION DESCRIPTIONS Stapling mode B442D112.WMF B442D114.WMF B442D106.WMF The stapler is attached to the jogger tray, so all sets go to the jogger tray. After all pages of a set have entered the jogger tray and been shifted across, the paper exit link [A] pulls the paper exit unit [B] down until knob [C] on the exit unit pushes the link lever [D] for the exit unit switch [E].

Page 720 VIDEO DATA PATH First, the FCU stores the incoming data from either an analog line or an ISDN line to the SAF memory. (The data goes to the FACE at the same time, and is checked for error lines/frames.) The FCU then decompresses the data and transfers it to page memory. If image rotation will be done, the image is rotated in the page memory.
Page 721 FAX COMMUNICATION FEATURES 4.4 FAX COMMUNICATION FEATURES 4.4.1 PERSONAL/INFORMATION/TRANSFER BOXES When an incoming message has a SUB or SEP code attached, the machine will look for a Personal Box, Transfer Box or Information Box with an identical SUB or SEP code. If a matching code is found, the message will be stored in the box and not printed, or it will be forwarded to the receiver if registered.
Page 722 FAX COMMUNICATION FEATURES Transfer Box The user can create transfer boxes in the machine’s memory for forwarding incoming fax messages. Each box must have a name and a code. Each box must also have destinations associated with it; any message arriving in this box will automatically be sent on to these destinations.
Page 723 FAX COMMUNICATION FEATURES Information Box (Polling Tx) The user can set up documents in memory to be picked up by another machine. The user makes an information box for each document. The information box is identified by a code. Anybody who wishes to call the fax machine and receive the document from the information box has to input this code as the SEP code when calling the machine.
