Artograph MC250 - Manual (Page 5)

Insert a new Halogen lamp into the lamp
slider. DO NOT TOUCH THE LAMP WITH
YOUR BARE FINGERS! Oil from your
fi ngers reduces the lamp life.
Move the lamp slider with the lamp to the
right until it stops. The lamp is now inserted
into the lamp socket. Replace the heat
protection fi lter and the top glass.
Pilot Lamp Replacement
(Fig. 13)
The pilot lamp is located in a compartment
on the bottom side of the unit. Move the
cover of the compartment in direction of
the arrow. Now the lamp is visible and can
be easily replaced.
Changing the Fuse (Fig. 14)
The fuse socket is located on the bottom
of the unit. It is unlocked by turning the
screw top in a counter clockwise direction.
Replace with F4A fuse.
Overheating Protection
The MC 250 is specially fitted with a
thermal safety switch, which will turn off
the lamp in the event of overheating (check
to ensure that the ventilation slots have
not been inadvertently covered). When
the projector reaches a cooler operating
temperature, the lamp is switched on
automatically.
Projection Caution
Caution must be exercised whenever
photos or heat sensitive materials are used
in the projector. The MC 250 is designed
to provide maximum illumination with a
minimum of residual heat, however, with
extended use; the top copy glass may
attain temperatures suffi cient to affect the
quality of the heat sensitive materials. It is
highly recommended that copies should
be used for the projection of all valuable
photos or art materials. Artograph will not
be responsible for damage to any heat
sensitive materials.
MAINTENANCE
Lens: Clean lens with any commercial
lens cleaner and a soft cloth or lens tissue.
NOTE: Apply cleaner to cloth. Never apply
cleaner directly onto lens as it may seep
into the lens.
Mirror: The MC 250 incorporates a special,
front-surface mirror, which eliminates
double imaging and enhances brightness.
The silvered surface must be cleaned with
care. Use a mild cleaning solution and a
clean cloth or tissue. Do not scrub!
