Thanks for contacting us and for helping to make BCH Technologies on YouTube successful. Your input is invaluable for improving our technical prowess.

Error code 000684 on the Epson ET-16150 is linked to a problem with the Rear Automatic Sheet Feeder (RASF) motor. The following breakdown will highlight what might be causing this issue and provide a few suggestions for troubleshooting.

If the RASF motor is blocked or overloaded, you can manually exert pressure on it and check if it resists any of your movements. If the action seems smooth or stuck, it can trigger a malfunction.

Gears Disengagement/Breakage: Check the wheel train of the Rear ASF Unit drive for disengaged or broken gears and replace them accordingly. Motor failure, in which either the tooth breakage or gear breakage occurs, leads to impaired motor working.

RASF Scale Contamination: Dirt or debris on the RASF Scale may interfere with proper reading. Carefully clean the RASF Scale and remove all contaminants.

Cable/ Connector: Check the cable / FFC( Flexible Flat Cable ) between RASF Motor and Encoder for damage or disconnection. Only fix or replace damaged cables and connectors.

RASF Motor/Encoder Failure—The RASF motor or its encoder could be faulty. Verify that the motor leads are still connected and that the connectors have a good physical connection. As needed, replace the RASF Motor or Encoder.

Main Board Issue: The mistake can occur if the Main board is in trouble. If everything else is working fine, the Main Board must be replaced.

Recommended Procedures:

Performing a Manual Check: You should start by manually moving the RASF Motor from side to side and checking for any mechanical obstruction causing an error.

Gear Check: Inspect the Rear ASF Unit Driven gears for fractured teeth or disengagement

Through Cleaning of the RASF scale: Clean it thoroughly if contaminated.

Cable Inspection: Examine the RASF Motor/Encoder cable and FFC for broken wires or pull-outs.

If issues remain, replace the Rear ASF Unit or Main Board.

Printer problems are hands-on and, thus, are difficult to deal with. We are unable to do any over-the-phone troubleshooting or repair support with printers. We offer walk-in diagnosis and repair services at our local diagnostic facility https://bchtechnologies.com/printer-repair-service. Still, we operate on a first-come-first-serve basis due to high demands, so there may be several weeks of waiting time for drop-off or mail-in service. Indeed, our repair services are extensive, but they may only sometimes represent the most differential economically. For do-it-yourself people, we suggest looking online via places like our YouTube channel (https://youtube.com/@bchtechnologies). Where applicable, you can try searching on YouTube for specific repair videos that will take up possible solutions.
