2.4 CHANGING OR REPLACING THE PRINT HEAD

Before attempting to replace the print head, it is advisable to contact
your local dealer or service center so that they can assist you in case
of problems.
The S8400 series is designed for tool-less easy attachment and
detachment of the print head.
1. Make sure the printer has been turned off for at least 30 minutes so
that the print head is not hot. Lift up the front cover.
2. Push the Head Lock Lever (the purple slide lever) upwards. in the
direction shown here.
Caution
• Do not touch the print head's heating elements. If you do so inadvertently, use the
cleaning pen (supplied) to clean the area thoroughly. For more details, see Section 4,
Cleaning and Maintenance.
3. Pull up the Print Head Release Latch (circled in red). The print
head will drop downwards. Note the tall metal locking pin (circled
in blue) in the centre of the print head. A spring loaded plate
(controlled by the Print Head Release Latch) is pressed against the
sides of this locking pin to fasten the print head in place.
4. Pull the print head outwards and disconnect the two cables and
connectors attached to it. Connect a replacement print head to the
two connectors.
5. Insert the print head back into the printer starting from the point
labeled A here. Make sure the front-most part of the print head
makes contact with the plate circled green.
6. While pulling the print head release latch, push the area labeled B
upward until the print head is horizontal. Let go of the release latch
so that the spring loaded plate inside will press against the central
locking pin to hold the print head in place.
