Printhead Installation and Removal Procedures

Printhead removal procedure

NOTE: Screws are fitted with washers.

2)Place your hand (with static gloves on) underneath the print line of the print head and pull down guiding screws through keyhole slots. This will remove the print head assembly from the mount plate. You may need to "help" the print head out by pushing on the heat sink with your left hand.

4)Remove the old printhead carefully from the heat sink.

Printhead installation procedure

1)Place the new print head onto the heat sink.

2)Replace the two print head mount screws. Be sure that the head is resting flat on the heat sink before tightening these screws.

3)Replace the print head assembly in the printer, sliding screw / washer (Paragraph 1 - Printhead removal procedure) into the holes in the mount plate. Make sure that the screw / washer slides all the way to the front of the holder. Tighten screws.

4)Reconnect the print head cable connectors, making sure that the connectors are seated tightly.

NOTE: If the cable is not connected correctly, the print head will be destroyed when the machine is powered on. Check to see that the cable is tight by observing from underneath the print head. The cable’s connectors should be inside of the connectors located on the print head.
