Printhead Replacement Guide

Print nozzle test to confirm which Print Head is needing to be replaced

Confirm the print carriage is in the home position and Print Heads are capped

Press the emergency stop button, turn off the power switch, unplug the printer power switch from the wall socket. Leave off

Remove the two thumb screws for the carriage cover, then remove cover

Locate the Print Head that will be replaced, based on the nozzle test

Remove all four dampers from the Print Head

Locate the Damper heater power cable, disconnect it from the black Molex wire connection

Locate the three Phillips head screws that secure the Damper Heater and the Print Head to the print carriage

Completely loosen the three screws first, then gently lift the Damper Heater from the Print Head, the three screws will lift with the Damper Heater

Gently remove the Print Head from the print carriage

Carefully remove the waterproof tape from each side of the Print Head, used for sealing the Ribbon Cable connection

Before removing the Ribbon Cable, label each Ribbon Cable with permanent marker using a 3-character code:

1,2,3 & 4: Refers to the Print Head that the Ribbon Cables are connected to

L or R: Refers to the Left or Right side of the Print Head

U or D: Refers to the Ribbon Cable connection position for that particular Ribbon Cable. U stands for "UP" or top connection, D stands for "DOWN" or the bottom connection

Example: Head 3 Ribbon Cables should be labeled 3LU 3LD & 3RU 3RD

After labeling the Ribbon Cable, gently remove the Ribbon Cables

Place the removed Print Head on a clean, dry, lint free cloth or in its original black plastic packaging

Lower the Capping Station by rotating the manual wheel counter-clockwise until the Cap Tray is at the lowest position

Carefully remove the new Print Head from the black plastic packaging

Reconnect the Ribbon cable to the Print Head, referring to the 3-character code that has been written on the cables for correct connection positions

Using 2in strips of waterproof tape, seal the Ribbon Cable connection on the left and the right sides of the Print Head

Carefully place the Print Head into its slot on the Print Carriage

Set the Damper Heaters on top of the Print Head

Drop all three screws into the corner holes of the Damper Heater. Gently rotate the Damper Heater until the screws align and drop into the corner holes of the Print Head

Tighten screws down until they meet the top of the Damper Heater. Do not tighten down the screws until all three screws are meeting the top of the Damper Heater. this will prevent the Print Head from being installed crooked or skewed

Tighten the three screws until the Damper Heater is flush to the Print Head, and the Print Head is flushed with the Print carriage. Do not over tighten the screws

Reconnect the Damper Heater cable to its black Molex connection
