How to Fix OF1 POST Error for Xerox VersaLink C7020 C7025 C7030 C7000 Printer?

Posted by Xwk Tech on


Use this RAP when the UI has stalled and shows the splash-logo screen, or the system appears to have power but the UI is blank.

• Power on Self Test (POST) occurs each time the machine is powered on. POST verifies the functionality of key subsystems.
• POST begins when power is switched on before higher level machine functions (such as the user interface) are operational.
• POST is performed by the ESS PWB.
• The fault is communicated via an eight LED display on the ESS PWB. This is to help diagnose common faults which prevent the machine from powering up correctly to the point where faults are displayed and service mode can be entered.


WARNING: Ensure that the electricity to the machine is switched off while performing tasks that do not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause death or injury. Moving parts can cause injury.

To check for the system power up error:

1. Switch off, then switch on the machine, GP 10.
2. If the system power up sequence has failed, check the code on the eight LED display.

Refer to:

• BSD 3.10 ESS Status LED (1 of 5)
• BSD 3.11 ESS Status LED (2 of 5)
• BSD 3.12 ESS Status LED (3 of 5)
• BSD 3.13 ESS Status LED (4 of 5)
• BSD 3.14 ESS Status LED (5 of 5)

If the eight LED display indicates a related fault code, perform the relevant RAP. If a related fault code is not listed, Perform the OF2 Special Boot Modes RAP. If the fault persists, install a new ESS PWB, PL 3.10 Item 6.
