Print Head Replacement
NEVER REMOVE THE PRINT HEAD FROM THE PRINTER EXCEPT FOR
REPLACEMENT.
TURN OFF THE POWER TO THE PRINTER BEFORE STARTING ANY
ELECTRONIC COMPONENT REPLACEMENT.
NOTE: The Anti-static wrist strap (which must contact the skin and be tight) and
anti-static gloves must be worn at all times when handling a print head to
avoid damaging the print head.
1) Review the Printhead Handling Procedure Sheet packaged with each print head to
determine if any procedures have changed before beginning this procedure.
2) Remove the media and ink from the machine for easy print head removal.
3) Unplug the cables that connect to the print head. Unplug the cable by firmly, but
gently pulling it out.
4) Loosen (2) 6-32 Phillips screws visible through holes in the upper print head
holder. Slide the head toward unwind end of printer.
NOTE: Screws are fitted with washers.
6-32 PHILLIPS SCREWS
5) 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.
6) Remove the two print head mount screws located on the top of the print head with
a Phillips head screwdriver.
