Flushing a Print Head

This procedure is 

not

 performed daily. It is performed as a last resort to clear blocked 

nozzles. It should only be performed by a trained operator. Contact your Customer Service 

representative for assistance with this procedure. See "Materials" on page B-1 for 

information about ordering the correct cleaning fluid or flushing fluid.

1.

Access the carriage assembly via the control panel using the Operator/Maintenance/

Access Carriage menu.

2.

Open the doors on the left end of the printer, then lower the maintenance station to 

expose the print head nozzle plate, as shown in 

Photo 2

. Place a shallow 9-in. x 14-

in. (23-cm x 36-cm) pan on top of the maintenance station.

3.

Locate the print head to be flushed. Disconnect and cap the ink line coming from 

the ink reservoir to the selected print head to prevent ink spillage.

4.

Depending on the ink type, fill the syringe with cleaning fluid (for 5500/6600 series 

ink) or flushing fluid (for 440 series inks),

then attach it to the ink line going into the 

disconnected print head. 

Flush the print head into the pan below (positioned on top of the maintenance station). 

Looking from the carriage face plate level, visually check to see the fluid exits the print head 

nozzles evenly

(straight down versus multidirectional streams of clear fluid) into the pan 

from the print head.

5.

Disconnect the syringe from the head ink line, then reconnect the head and reservoir 

ink lines back together.

Remove the catch pan, return the carriage to the home position and close the left-

end doors. Run a 

long

 purge of all colors to prime the print heads. Run a 

low

 or 

high

purge for all colors to generate a nozzle test print to verify all nozzles are firing. 

Warning:

Do not allow any air to enter the print head.
