Ink Absorber Box, Ink Absorber Felt, And Pf Encoder Disk - Brother DCP6690CW Service Manual

6.1.13 Ink Absorber Box, Ink Absorber Felt, and PF Encoder Disk

Note: Do not remove the ink absorber box unless it needs to be replaced.
Note: If the main PCB is replaced without backing up the machine information, the ink
absorber box (and flushing box) should also be replaced.
Note: Once the main drain tube is removed from the ink absorber box for the replacement of the
ink absorber box, it will become unusable and new part will have to be put back in. Using the
removed tube again may result in an ink leakage.
(1) Pull out the main drain tube from the ink absorber box.
Note: Pinch the end of the main drain tube with a clip in order to prevent drained ink from
leaking and the machine from getting stained with leaked ink.
Note: Do not place the main drain tube that has been pulled out on the main PCB. If the
PCB is stained with leaked ink, wipe it off with a dry cloth.
(2) Pull the ink absorber box up and out of the lower cover.
(3) Immediately set a new ink absorber box. Then replace the tube; that is, pull it off the joint
on the rear of the maintenance unit and connect a new tube to the joint and new ink
absorber box as shown below.
Note: If the ink absorber box or its surroundings are stained with ink, wipe them off with a
cloth.
(4) Take the ink absorber felt out of the lower cover.
