Page 62: Scanning
The light reflected by the reflector is of almost equal intensity, to reduce shadows on pasted originals. An optics anti-condensation heater [G] is available as an option. It can be installed on the left side of the inner cover. The heater will turn on whenever the power cord is plugged in. (A193)
Page 63: Scanner Drive
Magnification in the sub-scan direction can be adjusted by changing the ADF motor speed using SP6-007. In the main scan direction, it can be adjusted with SP4-008, like for book mode. Refer to setion 4.2.2. (A193)
Page 64: Original Size Detection In Platen Mode
The main CPU will identify the original size from the on/off signals from the APS sensors. If the copy is made with the platen fully open, the main CPU will identify the original size from the sensor outputs when the Start key is pressed. (A193)
Page 65 However, in this machine, for each page, the data signal to the laser diode is stopped to match the copy paper length detected by the registration sensor. Original size detection using the ADF is described in the manual for the ADF. (A193)
Page 66: Image Processing
FCI: Smoothing (binary picture processing mode only) • LD controller: LD print timing control and laser power PWM (Pulse Width Modulation) control On completion, the BICU board sends the video data to the LD drive board at the proper exposure time. (A193)
Page 67: Sbu (Sensor Board Unit)
After the above processing, the analog signals are converted into 8-bit signals by the A/D converter. This will give a value for each pixel on a scale of 256 grades. Then, the digitized image data will be sent to the BICU board. (A193)
Page 68: Auto Image Density (Ads)
ADS corrects for any changes in background density while scanning down the page. As with previous digital copiers, the user can manually select the image density when selecting auto image density mode, and the machine will use both settings when processing the original. (A193)

Page 73 To convert the mirror image, the CPU stores the main scan line data in the LIFO (Last In First Out) memory of the magnification block, from the last pixel. When loading the main scan line data from the LIFO memory, the CPU loads the first pixel of the main scan line. (A193) 2-12...
Page 74: Gamma (Γ) Correction
(Users requiring grayscale mode output for multiple copies will have to make a succession of one-to-one copies.) For one-to-one copying, the processing mode used depends on the setting of the service program mode, SP 4-403. The factory setting is for grayscale processing. 2-13 (A193)
Page 75 The printout density of the black pixel depends on the pixel type (left, center, or right of a series, or isolated, in the same way as for grayscale processing). These values can be adjusted using service program mode, SP2-904. (A193) 2-14...
Page 76: Line Width Correction

Page 450 The pressure of the pressure roller can be changed in the same way as for the A193 machine. It is done by adjusting the position of the pressure springs [A]. In this machine, the fusing pressure can also be adjusted with the lever handle [B] (this is a finer adjustment than the pressure springs).
Page 451 The fusing unit fan [A] has been added below the fusing unit. The fusing unit fan is necessary because the wattage of the fusing lamp is higher than in the A193 machine, as a result of the higher copy speed. The fusing unit fan turns on if the charge roller thermistor detects a temperature in the machine of over 43°C when the main motor starts to rotate...

PARALLEL MEMORY TRANSMISSION 2. PARALLEL MEMORY TRANSMISSION Using basic memory transmission, normally the machine starts dialing after the document has been completely scanned. Using Parallel Memory Transmission, the machine starts dialing at the same time the machine starts scanning. If the document has multiple pages, the machine scans them into memory and sends them while scanning continues.

Page 560: Transfer Broadcasting
TRANSFER BROADCASTING 3. TRANSFER BROADCASTING This machine uses a new algorithm to identify the requester’s fax number to send back the transfer result report. Previously, the transfer result report did not sometimes reach the requester with the old algorithm. In a transfer broadcasting operation, the transfer requester informs its own fax number to the transfer station.

Page 563: Original Scan Process
ORIGINAL SCAN PROCESS 4. ORIGINAL SCAN PROCESS The machine scans at 400 dpi. The other end may have a different paper size or may not be able to print at 400 dpi. The base copier’s scanner and BiCU work together to get the required resolution and size for transmission. 4.1 MAIN SCAN DIRECTION The base copier’s scanner always scans at 400 dpi (main scan direction).

Page 566 SMOOTHING 7. SMOOTHING When the fax unit prints a received fax image, the FCU converts the data into either 400 x 400 dpi, 16 x 15.4 l/mm, or 15.4 x 16 l/mm (image rotation) resolution, and smooths the image. The FCU then sends the smoothed data to the printer in the 64 gradation levels + 3 laser pulse positions format used by the base copier.
