Question about Ricoh Office Equipment & Supplies
Error sc 490 help
It is a cooling fan that has died.....I copied the following directly from the service manual. It's been a while since I've seen one of these machines, but the fan is either inside the rear panel, or accessible through either side (wherever there are vents in the panels basically). If you're at all technically inclined you can usually tell which fan it is by simply spinning it, and if it's not free, it is trouble...fairly standard fans, as long as you get the proper direction of airflow, and similar amps.
