Automatic document feed 1) Use of the paper feed roller and separation rubber plate ensures error-free transport and separation of documents. The plate spring presses the document to the paper feed roller to assure smooth feeding of the document. 2) Document separation method: Separation rubber plate Separation rubber Front sensor Paper feed roller CIS unit ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; Feed plate Document Paper feed roller Fig. 1 Fig. 3 3-3. Documents applicable for automatic feed 2. Document feed operation 1) The original, which is set in the document hopper, feeds automatically when the front sensor is activated. This in turn activates the pulse motor which drives the document supply roller. The document stops when the lead edge is detected by the document sensor. 2) The lead edge of the original is fed a specified number of pulses after the lead edge of the document is detected for the reading process to begin. 3) The trailing edge of the original is fed a specific number of pulses after the trailing edge of the document deactivates the document sensor. The read process then stops and the original is discharged. 4) When the front sensor is in the OFF state (any document is not set up in the hopper guide), the drive will be stopped when the document is discharged.

The document feed quantity may be changed according to the document thickness. Documents corresponding to a paper weight heavier than 69.2kg (80g/ m2 ) and lighter than 135kg (157g/m2 ) are acceptable for manual feed. Documents heavier than 135kg in terms of the paper weight must be duplicated on a copier to make it operative in the facsimile. 3. Hopper mechanism 3-1. General view 3-4. Loading the documents 1) Make sure that the documents are of suitable size and thickness, and free from creases, folds, curls, wet glue, wet ink, clips, staples and pins. 2) Place documents face down in the hopper. i) Adjust the document guides to the document size. ii) Align the top edge of documents and gently place them into the hopper. The first page under the stack will be taken up by the feed roller to get ready for transmission. NOTES: 1) Curled edge of documents, if any, must be straightened out. 2) Do not load the documents of different sizes and/or thicknesses together. Fig. 2 The hopper section contai

FO-77U UX-66U CHAPTER 5. CIRCUIT DESCRIPTION [1] Circuit description 1. General description The compact design of the control PWB is obtained by using CONEXANT fax engine in the main control section and high density printing of surface mounting parts. Each PWB is independent according to its function as shown in Fig. 1. 3. Operational description Operational descriptions are given below: · Transmission operation When a document is loaded in standby mode, the state of the document sensor is sensed via the 1 chip fax engine (FC200). If the sensor signal was on, the motor is started to bring the document into the standby position. With depression of the START key in the off-hook state, transmission takes place. Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line. In the scan processor, the signal scanned by the CIS is sent to the internal image processor and the AD converter to convert the analog signal into binary data. This binary data is transferred from the scan processor to the image buffer within the RAM and encoded and stored in the transmit buffer of the RAM. The data is then converted from parallel to serial form by the modem where the serial data is modulated and sent onto the line. 2. PWB configuration TEL/LIU PWB CIS CONTROL PWB · Receive operation There are two ways of starting reception, manual and automatic. Depression of the START key in the off-hook mode in the case of manual receive mode, or CI signal detection by the LIU in the automatic receive mode. First, the FC200 controls the procedure signals from the modem to be ready to receive data. When the program goes into phase C, the serial data from the modem is converted to parallel form in the modem interface of the 1 chip fax engine (FC200) which is stored in the receive buffer of the RAM. The data in the receive buffer is decoded software-wise to reproduce it as binary image data in the image buffer. The data is DMA transferred to the recording processor within the FC200 which is then converted from parallel to serial form to be sent to the thermal head. The data is printed line by line by the FC200 which is assigned to control the motor rotation and strobe signal. LCD PWB POWER SUPPLY PWB PANEL PWB TX/RX MOTOR AC CORD Fig. 1 1) Control PWB The control PWB controls peripheral PWBs, mechanical parts, transmission, and performs overall control of the unit. This machine employs a 1 chip modem (FM209) which is installed on the control PWB. · Copy operation To make a copy on this facsimile, the COPY key is pressed when the machine is in stand-by with a document on the document table and the telephone set is in the on-hook state. First, depression of the COPY key advances the document to the scan line. Similar to the transmitting operation, the image signal from the CIS is converted to a binary signal in the DMA mode via the 1 chip fax engine (FC200) which is then sent to the image buffer of the RAM.
