What to do if my Oki Printer shows a Scope-FD send error detected by Controller (Parity error)?
- JJeffrey MillsJul 31, 2025
If your Oki Printer shows a Scope-FD send error detected by the Controller (Parity error), it means the communication failed because an acknowledgement wasn't received after two resend attempts, or a parity error was detected in the IOT hardware. Try powering the printer off and on. If the problem persists, check the connection of the HVPS/MCU connect harness. If the issue continues, replace the HVPS/MCU PWB.
