5.3 Diagnostic flowcharts

Use the flowcharts that follow to determine the exact problem when either the online or offline diagnostics indicate a group error. Refer to Chapter 4 for parts replacement.

5.3.1Group 1 error flowchart (Lamp assembly)

This flowchart applies when the Ready and the Paper Jam LED each blinks 6 times the same while, with the scanner offline.

Group 1 Error

Yes	No Lamp is on?

CCD error Replace optical assembly

End of test

Inverter error Replace lamp inverter circuit

Yes

Lamp is on?

No

Replace the lamp

5.3.2Group 2 error flowchart (Flatbed/ADF motor)

This flowchart applies when the offline diagnostics error indication is the simultaneous blinking 5 times of the Ready and Paper Jam LED.

Group 2 error

Flatbed			No
motor
moves?
	Yes


ADF/Flatbed home				Flatbed motor error
position sensor error
Replace home				Replace flatbed
position sensor				motor
