Causes: 

• CSIC control error.

• The drive circuit damage in the Print Head was caused by the 42V fuse blew out of the Main Board

Troubleshooting Guides: Check the resistance between terminal on the Main Board “F12”.

1. If the resistance of “F12”on the Main Board has more than “1Ω” => The fuse of the Main Board has blown. It is

necessary to check whether drive circuit has broken in the Print Head.

[CHECK]

Pull out the Print Head FFC from Main Board (Don’t pull out the FFC from Print Head) “CN400” and, check the resistance between “15”-”19” of FFC terminal.

• more than “1MW” : Go to process “1”

• less than “1MW” : Go to process “1” and “2”

2. If the resistance of “F12” on the Main Board has less than “1Ω” => The fuse is normal of Main Board. Go to process “3”

1. Replace the Main Board.

2. Replace the Print Head.

3. Replace the Ink Holder.
