Code: 14-703B ... 14-706B, 712B, 714B
Description: Failure To Calibrate RAP (65-87 ppm)
Remedy: shows the component location. Switch off the machine, then switch on the machine, GP 14. The fault is still present. Y↓N→Perform SCP 6 Final Actions. Perform the following: • Remove the DADH. • Remove the scanner top cover. • Reinstall the DADH. Go to Flag 1 and check the voltages at P/J135 on the power distribution PWB. As necessary, refer to: • 01D +3.3V Distribution RAP. • 01F +12V Distribution RAP. • 01G +24V Distribution RAP. • 01B 0V Distribution RAP. Check the wiring between P/J135 on the power distribution PWB in the image processing module and P/J455 and P/J450 on the scanner PWB. Repair as necessary or install a new power distribution PWB/scanner PWB harness, PL 14.16 Item 7. Perform dC640 Video Path Diagnostics. The machine passes the diagnostic check. Y↓N→Check that all scanner harness connectors are correctly seated and that all wiring is in a good condition. Install new parts as necessary.
