Cautionary Notes When Performing Installation
 Do not touch the transparent glass part of the halogen heater you are going to use for
replacement. If touched, wipe off the surface of the glass with an alcohol based cleaner.
 Be careful not to let the protruding glass portions of the halogen heaters hit each other.
 Note that the central line density is different between the main and sub halogen heaters.
When installing them, be careful of their installation position.
In the inner side of the Printer:
Install the [FL02]SUB, whose central line density is low.
 After replacing, be sure to align the halogen heater position again.
 When installing, make sure that the insulators on both sides of the halogen heater are inserted
securely into the grooves on the plate.
Also, make sure that the insulators linear portions stay vertically (do not lay them down or put
them at an angle).
