Question about Ricoh Aficio AP3800C Laser Printer
I am getting a flashing message on my board that reads "CS 307, Power off/on, If error reoccurs call for service.
The manual states I should get the message CALIBRATING for 5 minutes. I can't clear the CS 307 message.
What is this problem?? I already tried reinstalling the drum twice. HELP!!!
You most likely have a defective "yellow" PCU . Try replacing that.
Otherwise you have a high voltage problem
