WC-5945, WC-5955, AltaLink B8090, B8075, B8065, B8055, B8045
The WorkCentre 5945 & 5955 MFP copiers are starting to show up on the secondary markets as more of them come off lease agreements. At the same time, the new AltaLink B8090 family continues to roll off the production line.
A few months back, we had a look at some of the basics of how to use the diagnostics and how-to backup and restore the NVM (non-volatile memory). Now let’s focus on the fault code meaning, particularly those which need to be reset from the NVM read/write memory settings.
Compiling the fault code list made it clear that the engineers of this series have decided to simplify things somewhat for customers and technicians—it’s a really good sign. For years now, each new wave of machines seemed to have more and more possible fault codes to contend with, and most of them didn’t lead to any useful troubleshooting in the service manuals. More codes did not turn out to be more helpful, they were simply confusing overkill. This machine’s list is a lot shorter than the C123 style machines, and that’s an improvement worth applauding.
Here is the abbreviated list:

Clearing some fault codes:
Fuser faults (310-320, 310-330, & 310-340) and toner concentration faults (393-360 to 393-364) need to be reset from NVM read/write (non-volatile memory) in diagnostics as described below:
1. First enter diagnostic mode:
- Hold down “0” button for seven seconds
- While still holding “0,” press “Start,” then release both buttons. (Note that for the new B8090 family you would instead hold the “Home” button for 10 seconds and then release)
2. The machine will prompt you for a passcode. Enter the default code “6789” and touch “Enter.”
3. Next go to NVM read/write:
- Choose the “Adjustments” Tab and touch the “dC131 NVM read/write” button.
- The NVM code to reset is “501-359” system lockout fault.
4. Enter the system lockout fault NVM code:
- Enter the first 3 digits (this is the NVM ID, in this case “501”), followed by the second set of digits (this is the NVM Index, n this case “359”).
5. Enter a “0” under the heading “Value of 501-359” and select “Write,” followed by “Close.”
6. Finally exit diagnostics & reboot:
- Choose “Call Closeout” and “Exit and Reboot.”
Voila!—the fault is re-set. And assuming you fixed whatever triggered the fault in the first place, the machine will come to ready again.
