Causes: Use this RAP if the machine powers up but fails to boot.
Remedy: 1. Switch off the machine, then switch on the machine. 2. Check the memory DIMM is correctly installed. 3. If necessary: a. Install new components: • Memory DIMM . • Hard disk drive . b. Perform OF7 Main PWB Check RAP
Code: OF7
Description: Main PWB Check
Causes: Use this RAP to check the main PWB. This RAP must be performed before a new main PWB is installed
Remedy: PWB Checks The following steps are used to diagnose a fault with the input voltage to the main PWB or output voltage from the main PWB. Perform the following: 1. Ensure the supply voltage is within specification, refer to GP 7 Machine Specifications. If possible, connect the machine directly to a known good power supply. If possible, do not connect the machine to a multiway connector or power strip that is being used to supply power to other electro-mechanical devices. Card readers, printers and PC’s are known to cause problems for Xerox equipment if they share a power supply. If the customer’s power supply is faulty, inform the customer. 2. Refer to Wiring Diagram 6. Disconnect CN26 from the Main PWB. Check the output voltage from the connection PWB . If necessary, install a new connection PWB. If the output voltage from the connection PWB is good, reconnect CN26. Check the voltage on the main PWB. Repair the wiring as necessary. 3. Refer to Wiring Diagram 2, Wiring Diagram 3, Wiring Diagram 5 and Wiring Diagram 7. Actuate each component connected to the main PWB. Check that the signal voltage from each component changes state. Check the wiring or install new components as necessary. 4. Check all connectors on the main PWB. If necessary, remove any oxidisation from the pins and connectors. 5. If the fault is still present, perform the Software Checks. Software Checks The following steps are used to clear any memory or software faults. The customers settings will be reset to default. Ensure all customer data is recorded before clearing the memory. Perform the following: 1. Print the System Configuration and Fax Phone Book (TBD) reports, refer to GP 5. Enter dC132. Initialize the Copier NVM, Network NVM and Fax Card NVM. 2. Reinstall the machine firmware, refer to GP 6 Firmware Upgrade. 3. If the fault is still present, perform the Final Actions. Final Actions Perform the following: 1. Install a new main PWB . 2. Perform GP 15 Shading Test.
