There are two SD card slots (center slot is not used). Model G160/G161 can use slot 1 to store application programs.
Page 232: Undo Exec
G160 Service Manual 23-Feb-06 Make sure that an SD card is in slot 1. The application program is copied to SD card in slot 1. Insert the SD card (having stored the application program) to slot 3. The application program is copied from this SD card. Turn on the main power switch.

Page 236: Board Structure
G160 Service Manual 23-Feb-06 Board Structure The EGB (Engine Board) controls machine functions along with the CTL (Controller). The IOB (In/Out Board) controls input/output, drivers and input/output connections. The IOB is part of the EGB expansion board. You can only install two of the optional interface boards (IEEE1284, IEEE802.11b, Bluetooth, USB Host and Gigabit Ethernet) at the same time.

Page 239: Process Control
G160 Service Manual 23-Feb-06 Process Control Overview This machine has the following two forms of process control: Potential control Toner supply control Process control uses the following components: Three ID (image density) sensors (left [A], center [B], and right [C]). Only the center ID sensor is used for process control.
Page 240 G160 Service Manual 23-Feb-06 : Drum potential at the strongest exposure – to adjust this, the machine adjusts the laser power. (Also, V is corrected. This is used for toner supply control.) This controls the development potential to make sure that the maximum quantity of toner applied to the drum is constant.
Page 241 G160 Service Manual 23-Feb-06 This starts before the next print job if the machine has no job for 6 hours. If the non-use time process control is done (N) times after the user turns on the power, it will not be done. N is adjusted with SP 3558.
Page 242: Toner Supply Control
G160 Service Manual 23-Feb-06 Step 4: Toner Amount Calculation The quantity of toner on the transfer belt (M/A, mass per unit area, mg/cm ) is calculated for each of the 10 gradations of the sensor pattern. To do this, the machine uses the ID sensor output value from each gradation of the pattern.
Page 243 G160 Service Manual 23-Feb-06 2. Proportional control mode 1 (Pixel) This mode is used when the TD sensor becomes defective. Only the pixel count is used to control toner supply. The amount of toner supply can be adjusted with SP 3306 1 to 4. 3.
Page 244: Toner Near End/Toner End Detection
G160 Service Manual 23-Feb-06 Toner Near End/Toner End Detection Introduction Toner Near End To detect toner near-end the machine uses: Pixel count (memory chip on the toner bottle) Toner End To detect toner end the machine uses: Output from the toner end sensor [A] Toner Near End Detection The machine uses the pixel count.
Page 245: Developer Initialization
G160 Service Manual 23-Feb-06 Toner End Detection The machine detects toner end when the toner end sensor detects toner end 3 times in a row 3.1 seconds after toner was supplied. At this time, “Toner end” is recorded in the ID chip. Toner End Recovery The machine detects that the toner bottle was replaced if one of the following events occurs during a toner end condition:...
Page 246: Paper Feed
G160 Service Manual 23-Feb-06 Paper Feed By-pass Tray Feed and Size Detection Paper Feed Mechanism When the paper detection feeler [A] detects a sheet of paper, the by-pass solenoid [B] unlocks the feed shaft stopper at the left end of the by-pass feed shaft [C]. The by-pass feed shaft has the feed roller [D] and two cams [E].
Page 247: Laser Exposure
G160 Service Manual 23-Feb-06 Laser Exposure LD Safety Switch A safety switch turns off when the front cover or the right door is opened. As a result, the relay on the PSU cuts off the power supply (+5V) to the four LD boards. (The electric circuits go through the EGB and IOB.) The LD safety switch system stops the laser beam when the cover is open.

G160 Service Manual 23-Feb-06 Automatic Line Position Adjustment Overview YY, KK, CC, MM: Spaces between two lines of the same color KY, KC, KM: Spaces between a black line and a color line During automatic line position adjustment, the line patterns above are made eight times on the transfer belt.
Page 249 G160 Service Manual 23-Feb-06 Summary of Each Adjustment Sub scan line position for YCM The adjustment of the sub-scan line position for YCM uses the line position for K (color registration). The machine measures the gaps between the lines of each color in the pattern on the transfer belt.
Page 250 G160 Service Manual 23-Feb-06 data, but only if one of the following conditions occurs. At a set time after the previous adjustment. The default value is 360 minutes. You can adjust the time with SP 2153 13. When the temperature changed after a previous adjustment by more than a set value. The default value is "5°C".
Page 251 G160 Service Manual 23-Feb-06 Summary Table The below table shows when the automatic line position adjustment is done. It also shows the main SPs that control the timing of the adjustment. If SP 2153 1 is "Off", then the automatic adjustment is never done.

Page 253: Fusing Temperature Control
G160 Service Manual 23-Feb-06 Fusing Temperature Control Overall Procedure The machine starts to warm up the fusing unit to get the print ready condition. When the heating roller temperature gets to the idling ready temperature [A], the idling procedure starts to warm up the heating roller.
Page 254 G160 Service Manual 23-Feb-06 This prevents the heating roller’s overheating. After printing, the machine turns the heating roller with no heating. You can adjust the setting with SP 1912 7 At intervals of 4 hours if the machine is not used for a long time This prevents the deformation of the hot roller and pressure roller.
Page 255 G160 Service Manual 23-Feb-06 The increase is applied if the interval between jobs is greater than these values: OHP, Thick paper, or 1200 x 1200 dpi: SP 1104 24 Other types of job: SP 1104 27 Corrections for Small Paper Sizes (less than A5) These corrections prevent too much heating of the fusing unit when paper widths less than A5 are used.
Page 256: Drive
G160 Service Manual 23-Feb-06 If the thermistor output is less than 0°C for six seconds, SC541 occurs. If the heating lamp gets full power for 8 seconds after the heating roller gets to the print ready temperature, SC545 occurs. Drive After the toner image is transferred to the paper [A], it goes through the fusing unit.
