• Code: 181
• Description: CIS lamp abnormal
  After the CIS lamp trigger goes on, the CIS lamp is not detected on. Detecting the lamp on or off determines the peak white level value for shading correction. (If the peak level is determined to be below a certain level, the CIS lamp is judged to be off.)
• Causes: • CIS lamp defective
  • CIS power supply board defective
  • CIS lamp regulator defective
  • Harness between lamp and lamp regulator is disconnected.
  • Harness between CIS, ADF is disconnected
  • CIS exposure glass dirty.
  • White roller dirty or installed incorrectly
  • CIS unit defective

• Code: 183
• Description: CIS auto adjust error
  Automatic adjustment of the CIS unit failed.
• Causes: • CIS unit defective
  • CIS exposure glass dirty
  • White roller dirty or installed incorrectly

• Code: 184
• Description: CIS transmission error
  When the CIS is powered on, the ADF detects one of the following abnormal conditions on the CIS unit:
  • The SOUT signal does not go high within 1 s after power on.
  • The SOUT signal goes high within 1 s after power on, but the SBU ID cannot be read after 3 attempts.
• Causes: • CIS unit defective
  • Harness between the CIS, ADF is disconnected

• Code: 202
• Description: Polygon mirror motor error 1: Timeout at ON
  The polygon mirror motor unit did not enter "Ready" status within 20 sec. after the motor was turned on, or within 20 sec. after the speed of rotation was changed.
• Causes: • The polygon mirror motor PCB connector is loose, broken, or defective
  • Polygon mirror motor PCB defective
  • Polygon mirror motor defective
  • IPU defective

• Code: 203
• Description: Polygon mirror motor error 2: Timeout at OFF
  The polygon mirror motor did not leave "Ready" within 3 sec. after the motor was switched off. (The XSCRDY signal did not go HIGH (inactive) within 3 sec.)
• Causes:

  • The polygon mirror motor PCB connector is loose, broken, or defective
  • Polygon mirror motor PCB defective
  • Polygon mirror motor defective
  • IPU defective

• Code: 204
• Description: Polygon mirror motor error 3: XSCRDY signal error
  The polygon mirror motor "Ready" signal went inactive (HIGH) while the motor was operating at normal speed, even though the motor was neither switched off nor was there a request for a change in speed.
• Causes: • Electrical oise interference on the line with the motor signals
  • Polygon mirror motor PCB connector loose, broken, defective
  • Polygon mirror motor PCB defective
  • Polygon mirror motor defective

• Code: 205
• Description: Polygon mirror motor error 4: Unstable timeout
  The "Ready" signal (XSCRDY) was detected as unstable for more than 20 sec. while the polygon mirror motor was operating at normal speed.
• Causes: • Electrical noise on the line with the motor signals
  • Polygon mirror motor PCB connector loose, broken, defective
  • Polygon mirror motor PCB defective
  • IPU defective

• Code: 220
• Description: Laser synchronization detection error
  The 1st laser synchronization detection unit could not detect the line synchronization signal (DETP0) within 500 ms while the polygon mirror motor was operating at normal speed. Note: The unit polls for the signal every 50 ms. This SC is issued after the 10th attempt fails to detect the signal.
• Causes: • Laser synchronization board connector loose, broken, defective
  • Laser synchronization detection board is not installed correctly (out of alignment)
  • Laser synchronization board defective • IPU defective
