Ricoh SC623 Error Code
The main unit lost reliable communication with a paper bank or large-capacity tray option.
Paper Path
What This Means in Plain Terms
The main unit lost reliable communication with a paper bank or large-capacity tray option.
Loose connectors after moving the machine, a power glitch, or a failed option board are common. End users can reseat power and confirm the option is fully docked.
Safe things you can try
- Turn the machine and any attached paper bank off.
- Confirm the paper bank is fully pushed against the main unit and all covers are closed.
- Power the paper bank on first if it has its own switch, then power the main machine on.
- Try feeding from a different tray to see whether only the option tray is affected.
Do not do these
- Do not yank option cables while the machine is powered.
- Do not remove covers to probe connectors unless directed by a technician.
Never enter service mode or clear safety codes yourself. Those steps can damage the machine or leave a safety lock uncleared.
When to call for service
If communication with the paper bank still fails after a clean restart, schedule service.
