6. Replacing Parts
6-1-42. Removing the Needle Felt
GT-3 has stopped mounting the Needle Felts since K2994330 because the stuck ink around the Needle may
give damage to the spout on the Ink Cartridge. Remove the Needle Felts if the severe misfiring occurs in the
unit before K2994329.
There are two ways to remove the Needle Felts.
Process 1 is to remove the ink and Felts with the Needle Bracket dismounted (recommended).
Process 2 is to execute with the Needle Bracket mounted. For those who is not used to the machine
maintenance, e.g. Tubes, Needles and other mechanical operations, or some situation that you cannot have
space to dismount the Needle Bracket.
