Section 3 —C-30B Camera
MAINTENANCE
GENERAL CARE OF THE CAMERA SYSTEM
The C-30B Camera is designed to provide long, trouble-
free service if given the same care as other precision optical
devices. Care should be taken in handling the various
mechanisms to assure that they are not damaged,
LENSES
NOTE
Do n o t attem pt to disassemble lenses. The lens
assemblies are sealed; therefore, d irt should n o t get
on their inner surfaces.
To obtain maximum use from your camera, always keep
the external lens surfaces clean. When required, remove
loose dust w ith a soft camel-hair brush. Fingerprints and
other smudges can be removed with clean, high-quality lens
tissue. Avoid scratching the lenses while cleaning.
The fro n t and rear lens surfaces may be cleaned by
attaching the cleaning materials to a long rod. The rod is
then inserted through either the fro n t opening or the back
opening of the camera to reach each side of the lens to be
cleaned.
SHUTTER
NOTE
Do
n o t attempt
to
disassemble
the shutter
mechanism. I f the shutter does n o t perform properly,
consult your local Tektronix representative.
Düring manufacture special lubricants have been added
to the shutter, making further lubrication unnecessary
during its lifetime. It is essential that neither oil nor
graphite be used on the shutter mechanism, since either
substance may ruin it. Sluggish shutter Operation may be
the result of continuous wear or extreme environmental
conditions.
CAMERA BACK ROLLERS
Both the Pack-Film and Roll-Film backs contain two
stainless Steel rollers used in Processing exposed film .
These rollers may collect a buildup of film developing
solution and therefore should be inspected each time a new
film pack or film roll is inserted. If required, clean the
rollers before inserting new film .
Instructions fo r cleaning the rollers are found inside the
camera back door. Should these instructions be missing or
faded, the rollers can be cleaned by using a damp cloth or
cotton-tipped applicator to remove any deposits.
For the Pack-Film back, the rollers can be removed by
lifting the rear of the roller assembly up and out of the
camera back. To replace the assembly, set the rollers down
into the camera back. Then gently push the rear of the
roller assembly down into the camera back until the small
plastic retaining latch on the roller assembly catches and
hold the rollers in place.
LIGHT LEAK SEALING
Some of the parts used in critical light-leak areas o f the
camera have been sealed to adjoining parts with a black,
pliable, nonhardening, weather-stripping adhesive. If a light
leak occurs or if one of the previously sealed parts is being
replaced, it is recommended that No. 2 Permatex, 3M
weather-strip adhesive No. 8011 (or a material with similar
characteristics) be used as a light-sealing material.
