CHAPTER 3 ARRANGEMENT/FUNCTIONS OF THE ELECTRICAL PARTS
F. Variable Resistors, Light-Emitting Diodes, and Check Pins by PCB
Of the variable resistors (VR), light-emitting diodes (LED), and check pins found, those that may be used in the field are discussed: Note: 1. Some LEDs emit dim light because of leak current when OFF; this is a normal condition and should be kept in mind. · A press on the Copy Start key while the service mode description is being shown starts copying operation.
No. 101 102 103 104 105 106 Description Indicates the version of the master ROM (IC116). Indicates the surface temperature of the upper fixing roller (output of thermistor TH1). Indicates the activation voltage of the scanning lamp. (220 / 240 V model) Indicates the jam history. Remarks ROM parts revision number (See below) Same as above Same as above Same as above Same as above unit: °C

CHAPTER 4 SERVICE MODE
No. 109 Displaying the Jam History The copier retains a history of as many 40 jams (most recent). 2) Using the Zoom key (+) / (-), select the jam history number (1 through 40, a higher number means an older jam); then, press the OK key. 3) Press the OK key as necessary to find out the jam code, pick-up location, pick-up soft counter, and paper size.
4-5
CHAPTER 4 SERVICE MODE
For example, if the 13th most recent jam was a pre-registration roller delay jam picked up from the copier's cassette 1 (copy paper size of A4, soft count of 63021).
Enter `13' using the keypad.
The display shows jam location. (3: pre-registration delay jam) (Table 4-3, 4-4, 4-5, 4-6)
The display show the pick-up location. [. . . ] You may continue to make copies even when the DF is out of order; lift the DF, and place the original on the copyboard.

CHAPTER 5 SELF DIAGNOSIS
D. Sorter Self Diagnosis
Code Cause ·CPU or communication IC on sorter controller (faulty) ·Feeder motor (fails to rotate) ·Stapler guide bar swing motor (fails to rotate) ·Stapler unit swing motor (fails to rotate) Timing An error has occurred in the communication between the sorter and the copier. The home position sensor does not turn off when 2560 pulses of the motor drive signal have been generated. ·The stapler unit swing sensor does not turn off within 500 msec after the motor drive signal has been generated.
