Page 271: Photo Mode
IMAGE PROCESSING 26 January, 2001 Photo Mode Photo mode emphasizes grayscale processing to achieve the best possible reproduction of photographs and eliminate moiré by using the highest density and γ coefficient in the reproduction of grayscales and dithering. Print Photo performs smoothing and dithering for photos copied from magazines, newspapers, etc.
Page 272: Pale (Low-Density Mode)
26 January, 2001 IMAGE PROCESSING Pale (Low-Density Mode) Pale achieves image quality comparable with text mode, but of lower contrast. Pale employs an MTF filter stronger than that employed by the text mode and uses a darker γ coefficient, thus increasing the incidence of copying textured backgrounds. Ideal for copying extremely thin originals.

Page 274: Auto Shading (Shading Correction)
26 January, 2001 IMAGE PROCESSING Auto shading (shading correction) Auto shading does two things. • Zeroes the black level for each scan line of data • Corrects for variations in white level across the main scan. Background erase By default, this process is used only in text mode, pale original mode, and generation mode.
Page 275: Independent Dot Erase
IMAGE PROCESSING 26 January, 2001 Independent dot erase By default, this process is used only in text mode and generation mode to erase independent black dots appearing in the copy or reduce their image density. However, it can be enabled for other modes with the following SP modes. SP4903 Independent Dot Erase Level (Text) Independent Dot Erase Level (Text/Photo)
Page 276: Filtering

Page 299: Sensor Control Mode
DEVELOPMENT 19 January, 2001 Toner density control There are two modes for controlling and maintaining constant toner supply: sensor control (both direct and indirect) and image pixel count control. The mode can be changed with SP2-208-1 (Toner Supply Mode). NOTE: The factory setting is sensor control mode; image pixel count mode should only be used temporarily until a defective TD or ID sensor can be replaced.

DEVELOPMENT 26 January, 2001 6.9.7 TONER END RECOVERY If the front door is opened and then closed while a toner near end/end condition exists, the machine will attempt to recover. When the front door is closed, the toner supply motor turns on to supply toner. The machine checks the TD sensor output 2 seconds after the main motor turns on (Vtp), and the sensor is checked again every 1 second (Vtp The machine detects the toner concentration using Vref, Vt (10), Vtp, and Vtp...

26 January, 2001 PAPER FEED 6.11.5 PAPER END DETECTION If there is paper in the paper tray, the paper end feeler [A] is raised by the paper stack, and the paper end sensor [B] is deactivates. 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 307: Paper Size Detection
PAPER FEED 26 January, 2001 6.11.7 PAPER SIZE DETECTION The paper size switch includes four microswitches. Actuators behind the paper size dial actuate the sensors. Each paper size has its own actuator, with a unique combination of notches. To determine the paper size, the CPU reads which switches the actuator has turned off.

Page 318: Transfer Belt Charge
19 January, 2001 IMAGE TRANSFER AND PAPER SEPARATION 6.14.5 TRANSFER BELT CHARGE Mechanism B004D564.WMF The high voltage supply board [A] applies a positive current to the transfer belt [B] through the terminal block [C], terminal plate [D], and the bias roller [E]. The high voltage supply board adjusts the current to the roller to keep a small but constant current flow to ground through the belt, paper, and drum.
Page 319 IMAGE TRANSFER AND PAPER SEPARATION 26 January, 2001 Correction for paper width and thickness A range of SP modes is available in order to adjust the machine so it can handle papers of non-standard size and thickness. For paper width, there are two thresholds. The factory settings are 150 mm (5.9”) and 216 mm (8.5”).
