    Content This manual contains instructions for installing, using and maintaining the three different models of the AFP Mini-Medical Series of X-Ray film processors. This series includes the Mini-Medical, the Mini-Medical/90 and the Mini-Medical/EP processors. With the excep- tion of pre-set processing speed and developer temperatures, these three processors are identical in appearance, operation, maintenance and service.

  • Page 18: Operation

    Introduction Operation The processor is operated from the control panel. Basic processor functions are described in the following paragraphs. Figure 1-2 is a diagram of the transport system. Capabilities Mini-Medical processors develop, fix, wash and dry exposed RP type medical X-ray films of all sizes, from 4"...
  • Page 19 Introduction Transport System, (Cont'd) Figure 1-2, Transport System Before processing film, the processor must first be turned ON and allowed to bring the developer up to operating temperature. As the processor warms up, it runs for one (1) process cycle (approximately 5 minutes) and then remains in the Stand-By mode.

  • Page 20: Transport System 1-2

    Introduction Transport System, Cont'd) Film is pulled into the processor by the input roller set on the developer rack. The film then passes through the recirculating developer bath. As it leaves the developer, excess chemi- cals are squeegeed off by the exit rollers. This process is repeated in the fix, wash and dryer sections.

  • Page 21: Developer & Fixer Replenishment

    Developer & Fixer Replenishment Mini-Medical Series processors are designed to operate in either “Batch” or “Replenish- ment” mode. As such, replenishment chemicals may be replenished as necessary, with tank overflow being directed into a drain or collection container for disposal, or recycled until exhausted, then discarded and fresh chemicals installed.

  • Page 22: Dryer System

    Introduction Dryer System As film passes through the dryer, it is subjected to warm air from two linear infrared quartz heating elements and a pair of fans. Upon leaving the dryer the film is deposited in the receiving bin. Cover Interlock Switch To prevent accidental injury from moving parts, a mechanical safety switch is interlocked with the processor’s top cover.
