Feeder A digital black-and-white copier designed to accommodate the board may be used in combination with the DADF-A1 (document feeder), which is equipped with a stamping function. reproduction ratio with a feeder in use: 50% to 200% ■ DADF-A1 The DADF-A1 picks up and places originals on the copyboard automatically one by one for reading by the scanner. The originals are placed face-up (i.e.
CHAPTER 2 OPERATION AND TIMING B. Reading Operation 1. Reading for Memory Transmission Each original placed on the copyboard glass is read and stored in memory. A number of originals may be transmitted in a single communication. When the feeder is used, originals stacked in the feeder are read one after another in sequence. The originals read in copyboard mode and those read using the feeder cannot be combined. 2.
CHAPTER 2 OPERATION AND TIMING C. Memory The copier is equipped with two types of memories: the "page memory" is used to store images (read or received) temporarily for processing in preparation for printing; and the "image memory" is used to store transmission/reception image data after coding. 1. Page Memory The page memory stores image data which has been processed for reproduction ratio, resolution, image quality, and binary coding according to the selected fax mode.
CHAPTER 2 OPERATION AND TIMING The expansion memories of the FAX board are arranged on the copier's image processor PCB. If you are installing one RAM, be sure to install it to J723. (Using J724 only can cause E604 indication. The expansion memories are available as accessories.
CHAPTER 2 OPERATION AND TIMING D. Reading/SENT Stamp (DADF-A1 only) The stamping mechanism is part of the feeder (DADF-A1), and may be READ stamp or SENT stamp. A single stamp is used for both, and is designed to put a pink dot 3 mm in diameter. The stamping mechanism is enabled by operating "transmission settings" of "additional functions." It functions as follows: • It does not operate in copier, test shot, or copyboard mode. • It prohibits advance feed when picking up originals.
CHAPTER 2 OPERATION AND TIMING E. Memory Full Condition 1. Outline If the image memory becomes full while reading is under way for memory transmission (as detected by the CPU on the IP PCB), direct transmission mode will automatically be used starting with the page in question. Such modes as timer transmission and broadcasting, which are based on memory transmission, however, cannot rely on direct transmission even if the memory becomes full.

CHAPTER 2 OPERATION AND TIMING Table 2-202 shows various possible combinations of image quality and density.
CHAPTER 2 OPERATION AND TIMING G. Test Shot In a test shot, an image is read using the same conditions used for actual transmission: the memory is stored in memory once and then printed out. For this reason, the quality and arrangement of the image may be checked prior to actual transmission. It may also be used to look for an error in mechanisms from reading to storing in memory. Figures 2-206 and 2-207 show the Test Shot screen and the flow of image signals, respectively.
CHAPTER 2 OPERATION AND TIMING H. Reduction/Enlargement Images are processed for reduction/enlargement by the image processor for both transmission and reception. For ratios, see Table 2-203.

CHAPTER 2 OPERATION AND TIMING 2. Selecting Recording Sheets a. Outline When the default service data is effective, recording sheets are selected based on the cassette selection switch settings (A through D) in reference to the following descriptions: Priority Description 1 Sheet whose main scanning length is the same as the print size length and which can accommodate all the image. 2 Sheet whose main scanning length is not the same as the print size length but can accommodate all the image.
CHAPTER 2 OPERATION AND TIMING b. Cassette Selection Switch This function operates to select specific recording sheets to suit the needs of the user. As many as four cassette selection switches (A through D) exist as described in the following table. If printing on recording sheets of the same size as the received pages is desired, be sure to shift all cassette size switches A through D to OFF.
CHAPTER 2 OPERATION AND TIMING c. Recording Paper The FAX Board automatically selects the first recording sheet (cassette) that satisfies the following conditions; if none of the conditions is met, the board indicates a message to that effect, and starts memory reception (waiting for output). Priority Description 1 Has the same main scanning length. Is smallest of those capable of accommodating all the image (in Direct or by reduction up to maximum ratio). 2 Has the same main scanning length.

CHAPTER 2 OPERATION AND TIMING C. JBIG Image Compression Coding Method 1. Outline of the JBIG Image Compression Coding Method The JBIG image compression coding method is a new way of coding binary image data (black and white) developed by the Joint Bi-Level Image Experts Group, and its rules are standardized as part of ITU-T T.82/5.85. The JBIG image compression coding method provides a higher rate of compression than the existing MMR coding method (1.
CHAPTER 2 OPERATION AND TIMING Reference: The following is an outline of the progressive bi-level image compression method: An original image is read at a high resolution. The result is converted to a low resolution, and the resulting data is coded (compressed) and transmitted. The data is such that, upon reception, it immediately provides an overall “impression” of the original image, although at a low resolution.
CHAPTER 2 OPERATION AND TIMING 3. Coding an Image In the single progression sequential bi-level image compression method, a coding device is used to code an image based on the result of comparison between the current line and the immediately preceding line and on the result of prediction about the level of the pixel in question using a model template (to find out whether it will be white or black).
CHAPTER 2 OPERATION AND TIMING Reference: If a match is made, the line being processed will be referred to as “being typical.” If a non-match is made, on the other hand, the line will be referred to as “not being typical.” When making a prediction for the first line of an image, the background is used as representing the immediately preceding line. b. Figure 2-403 shows model templates (enclosed by thick lines).
CHAPTER 2 OPERATION AND TIMING c. The learning table, as shown below, consists of all 10-bit pixel patterns from the model template and the prediction levels and status numbers corresponding to these image patterns. The prediction level and the status number of the pixel in question are compared against the actual pixel by the arithmetic coding block each time the model template moves to the next pixel.

CHAPTER 2 OPERATION AND TIMING Example: The following explains how the learning table works; in the diagrams, the pixels 1 through 10 of the model template are all assumed to be white: 1. The pixel pattern of the model template will be 000h. 2. The level of prediction against the pixel in question “?” of the pixel pattern 000h is “white”; however, it is actually black, making the prediction “wrong.” 3.
CHAPTER 2 OPERATION AND TIMING 4. The model template moves to the next pixel. At this time, the pixels 1 through 9 are white and the pixel 10 is black in the model template. 5. The pixel pattern of the model template is 001h. 6. The level of prediction for the pixel in question “?” of the pixel pattern 001h is “white,” and the actual pixel is also white. As such, the prediction is “correct.” 7.
CHAPTER 2 OPERATION AND TIMING e. When the level of prediction has been found to be correct or wrong in reference to the actual pixel, model template, and rate of prediction table, the arithmetic coding block codes the result of prediction so that coded image data is generated and transmitted. f. Unlike the conventional MH or MR coding method, coding (arithmetic) by the arithmetic coding block does not use a conversion table.

CHAPTER 2 OPERATION AND TIMING When correct predictions continue, coding will be as follows: Here, the value of LSZ consisting of correct predictions will be assumed to be 100*1 (decimal) for all statuses. The area A will be within 8000 to 10000*2 (decimal), and uses the initial bit when it falls below 8000*3 (decimal), generating a coded image data output. At this time, adjustments are made (by adding 1000*4, decimal) so that the area A will be 8000*3 (decimal) or higher.
CHAPTER 2 OPERATION AND TIMING 4. Construction of Image Data by JBIG Image Compression Coding An image is coded in units of blocks called “stripes” as shown in Figure 2-409.
CHAPTER 2 OPERATION AND TIMING 5. Bi-Level Image Header (BIH) BIH may be expressed as the diagrams shown in Figure 2-411, and is used to indicate the size of an image, the number of lines per stripe, and the applicable model template.
CHAPTER 2 OPERATION AND TIMING 6.
CHAPTER 2 OPERATION AND TIMING 7. Bi-Level Image Data (BID) BID is constructed as shown in Figure 2-412, and as many RID units exist as there are stripes. BID consists of a combination of a floating marker code and an image data block which has been processed by JBIG image compression coding called “SDE” (stripe data entity).
CHAPTER 2 OPERATION AND TIMING ATMOVE (0x06) Indicates the line on which the shift of the AT pixel starts and the direction of the shift. ESC 0x06 Line to start (4 byte) Destination of shift (X) Destination of shift (Y) COMMENT (private comment; 0x07) Accepts a comment written at will.

CHAPTER 2 OPERATION AND TIMING D. V.8/V.34 Procedure Reductions have been made to the image transmission time using a V.34 standard modem complying with ITU-T (maximum transmission speed of 33600 bps). 1. V.8 Procedure The V.8 procedure starts a communication as if the type of device (existing modem, fax, Vseries modem) is not a factor. (See Figure 2-401.) n Receiving Modem Not Provided with V.8 The normal modem connection sequence will be executed. n Receiving Modem Provided with V.
CHAPTER 2 OPERATION AND TIMING 2. V.34 Modem The high-speed modem communication procedure recommended by ITU-T is referred to as "V.34," and may be described as follows: a. It communicates using half-duplexing mode of a 33.6 kbps modem complying with ITU-T. b. It automatically selects the most appropriate transmission speed (14 types; every 24000 bps between 2400 bps and 33600 bps). transmission speed = data speed (ITU-T recommendation) = data speed c. It uses ECM. d. It executes a start-up using the V.
