AFP Imaging Mini-Medical/90
AFP Imaging · Model Mini-Medical/90
Built-in quality control - Audible and visual indicators add to operator convenience by signaling when the processor is ready to accept another film Developer level and temperature indicator - Two separate indicator lights let the operator know the developer solution is at the proper level and that it has reached the optimum temperature for film processing Constant readiness design - A special "jog" cycle keeps rollers wet while the machine is in standby, thus guaranteeing quality processing throughout the day Automatic chemical replenisher - An electronic activating system replenishes solutions automatically keeping all chemicals used in the Mini-Medical at peak operating efficiency Interlocking crossover - Films travel from tank to tank with minimum exposure to air. The tank's new molded plastic uni-body design and the interlocking design of each rack simplify removal Automatic wash water control - Minimizes the consumption of water by eliminating flow during standby mode. Approximately 1 pint of fresh water is added during each "jog" cycle to eliminate algae problems associated with standing water Infrared dryer - Energy efficient "I.R. heat lamps" dry each film quickly and quietly. "Pivot-back" dryer rack enables easy access to wash section Simple installation - The AFP Mini-Medical runs on standard electrical current (115 VAC, 15 A) and requires only a cold water line connection. The unit is UL approved Automatic standby - During periods of inactivity, the drive motor and pumps shut off automatically reducing energy consumption and mechanical wear. Temperatures are maintained electronically Light-proof covered feed tray - Reduces time in the dark Silver recovery connection - Fixer drainage hose fittings are compatible with most standard silver recovery units Solid state circuitry - Modular, state-of-the-art electronics are designed to assure reliable operation with minimal start-up and reset times. An audible tone alerts operator that processor is ready to accept another film
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Developer / fixer chemistry exhaustion
HighSymptoms: Streaked, fogged, or underdeveloped films.
Root cause: Chemistry depleted past replenishment capacity, or contaminated.
Transport roller jam / film scratch
HighSymptoms: Film jams mid-cycle, or exits scratched.
Root cause: Worn transport rollers or guide shoes.
Dryer section fault
MediumSymptoms: Films exit wet or tacky.
Root cause: Dryer heater element or blower failure.
Replenishment pump failure
MediumSymptoms: Gradual image-quality drift across a batch.
Root cause: Worn peristaltic tubing or pump motor.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Developer / fixer chemistry exhaustion
- Confirm the presentation - typically streaked, fogged, or underdeveloped films - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: chemistry depleted past replenishment capacity, or contaminated.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the transport roller rack / set per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
