SUBJECT: recision Enlarger Prototype (BPE) Operational
Improvements and Maintenance
TASK/PROBLEM
1. Provide photographic enlarger maintenance at the customer's
facility for one Precision Enlarger (BPE) and three* 10-20-1+OX
Enlargers.
DISCUSSION
2. Contractor personnel visited the customer's facility during
the week beginning 31 March 1969 to perform six-month preventive
maintenance (PM) on the BPE, and two-month PM on four* 10-20-1+OX
Enlargers. (See check lists attached indicating the work performed.)
3. The six month PM on the BPE included a photographic checkout
of the lens assemblies. During this checkout, the "H" lens-focus
finding did not agree with the focus setting suggested on the drum
scroll (a difference of 5 digits). As a result, this lens was returned
to the factory for checkout. In addition, six "X" coordinate display
lamps (yellow base) were replaced with longer life lamps (green base).
The lamp problem is currently under investigation by the contractor
and the vendor (Theta Corp).
4. The two-month PM on the four* 10-20-40X Enlargers included the
following necessary adjustments and repairs:
a. Serial No. 101: "X" coordinate counter was inoperative;
the customer states that an order has
been placed for a new counter.
b. Serial No. 119: "Y" coordinate counter was repaired and
adjusted for proper operation.
c. Serial No. 113: LOX condenser (lens) piano glass was
replaced.
* Although the Task/Problem specifies preventive maintenance on three
10-20-1+0X Enlargers, the contractor regularly services four enlargers
on the basis of the customer's verbal request. The customer has stated
that he does not consider it necessary to revise PAR 21+9 at this time.
