How to fix LINE ERROR on Sharp AM-400 All in One Printer?
- Jjohn53Aug 22, 2025
A LINE ERROR on your Sharp All in One Printer indicates a communication problem with the other fax machine, usually due to a phone line issue. Try the transaction again. Check the connection, ensuring the cord from the TEL. LINE socket to the wall socket is no longer than two meters. Ensure no modem devices share the same telephone line. Verify the other party's fax machine is working. Have your telephone line checked for noise. Try a different telephone line. If the issue persists, your machine may need service.
