What to do if my MUTOH Valuevet VJ-628X Printer shows 'Cover open' error?
- DDr. Diana StanleyAug 3, 2025
If your MUTOH Printer indicates that the cover is open, ensure the switch board presses the sensor correctly by reinstalling it and tightening the screw on the cover sensor. Also, check that the cable is securely connected to the connector and that the interlock cable is securely connected to the MAIN board. If the issue persists, consider replacing the front cover sensors or the MAIN board.
