Remove the burned out bulb and replace it with a new one, using a cloth
or paper towel to handlethe bulb.
CAUTION
Never touch a copy light bulb with your bare fingers. The
body oils on the fingers cause a blemish on the bulb that
results in a hot spot burning out the bulb or causing it to
break.
Figure 28. Copyboard and lights
(3) The last area you check before turning on the camera is the
viewing area. Make sure the copyboard, split platen, and lower glass
are clean. Any spots or marks caused by dirt or grime in the viewing
area can show up as a spot on the finished print.
b. Making the Copy. To ready the camera to make copies, turn it on
and allow it to warm approximately 20 minutes. When the chemicals in
the camera reach operating temperature, the "ready" light comes on
(figure 27).
