Question about Ricoh Aficio 450 Copier
Please wait for extended time then SC 672. Have tried another HDD, reseated all connectors on control board and control panel as well as checked all other connectors. Tried reloading firmware thru sd card and didn't recognize the card. tried booting with HDD disconnected and still codes out with SC 672
Try checking or changing the thermistors!
The metal contact spring on the thermistor broken causing all sorts of 'unrelated errors including 'Please Wait' sc 670 and sc 402...
