Why does 'LINE ERROR' appear on my Sharp FO-51 Fax Machine?
- MMichael PinedaSep 6, 2025
If you see 'LINE ERROR' on your Sharp Fax Machine display, try the transaction again. If it continues, check the connection, ensuring the cord from the TEL. LINE socket to the wall is no longer than two meters. Ensure no modem devices share the line. Verify the other fax machine is working and check your telephone line for noise. Try a different telephone line. If the problem persists, your fax machine may need service.
