FR80 Maintenance Procedure

R Brandwood

8 October 1975

GENERAL

Preventive and corrective maintenance on the FR80 and 5010 is carried out under contract by the III Service Engineer. The contract provides for a 4-hour period of maintenance during prime shift. Work arranged outside prime shift attracts a surcharge (see FR80 Operator Notice 1).

Some maintenance is part of the operators' function. This includes tape deck and camera cleaning. The following procedure should be adhered to:

Avoid excessive use of alcohol, especially around roller bearings, where ingress of alcohol will dilute bearing lubricant.

Lenses and the PLS can be irreparably damaged by scratches or retained finger marks which contain acid that can etch into the optical coating. These surfaces should be cleaned in the following order:

1. Vacuum hose to remove large debris such as film chips.
2. Lens brush to remove dust.
3. Lens tissue (or Kleenex - not Kimwipes as they are too hard) and lens cleaning fluid to remove finger marks.

1. MATERIALS REQUIRED

Lens cleaning tissue 
Lens brush 
Lens cleaning fluid 
Squirrel-hair brush 
Alcohol 
Kleenex tissue 
Q-tips 

2. EVERY SHIFT

2.1 Cleaning tape drives

Use tissue moistened with alcohol to clean:

• The read/write heads
• The capstan
• All roller guides.

Then use dry tissue to remove any trace of alcohol.

Use a Q-Tip moistened with alcohol to clean EOT sensor light.

Use tissue to remove dust from ledges around tape drive and door.

2.2 Cleaning 5010 Film Processor

3. EVERY TIME FILM CASSETTE IS LOADED

3.1 Film cassettes

These are to be brushed out lightly (using squirrel-hair brush) to remove any dust, film chips, etc. Check that no hair from the brush is lodged into any part of the cassette.

Rollers on the cassettes are to be cleaned with a Q-Tip moistened with alcohol.
