Description: ID sensor pattern test error
One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. 1. Vsp greater/equal 2.5V 2. Vsg less than/equal 2.5V 3. Vsp = 0V 4. Vsg = 0V
Causes: • ID sensor defective • ID sensor harness or connector loose, broken, defective • IOB defective • HVPS board defective • ID sensor dirty
Code: 351
Description: ID sensor Vsg measurement error
When the ID sensor was checked twice, the ID sensor output voltage was 5.0V while the PWM signal input to the ID sensor was 0.
Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty
Code: 352
Description: ID sensor pattern edge detection error
The ID sensor pattern edge voltage was not equal to 2.5 V and two samplings within 800 ms.
Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty
Code: 353
Description: ID sensor, LED current abnormal at initialization
One of the following ID sensor output voltages is detected at ID sensor initialization. • Vsg less than 4.0V when the maximum PWM input (255) was applied to the ID sensor. • Vsg exceeded 4.0V when the minimum PWM input (0) is applied to the ID sensor.
Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty
Code: 354
Description: ID sensor timeout abnormal at adjustment
Vsg fell out of the adjustment target range (4.0 +- -0.2V) at the start of Vsg checking after 20 sec.
Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty
Code: 390
Description: TD sensor error: Abnormal measurement
The TD sensor output voltage was less than 0.5V, or more than 4.8V 10 consecutive times during copying. -or- The output was less than 2.5V after a new PCDU was installed.
Causes: • TD sensor connector or harness loose, broken, defective • TD sensor defective • IOB) defective • Toner supply defective (confirm that the toner seal strip has been removed from toner cartridge)
