Pentax EPK-i
Pentax · Model EPK-i
• Digital Power, Infinite Possibilities - Because the EPK-i is uniquely built on a robust computer-platform, there are literally an infinite number of tonal, brightness, and contrast digital filters that can automatically enhance and reveal the hidden colors of disease - without losing any of the native pixel data. • Ease-of-Use, Higher Care Modes - The EPK-i comes with three pre-set ease- of-use modes for PENTAX i-scan. You can even program your endoscope buttons to toggle through the modes, for always-on standard screening and disease validation. The three modes have been clinically evaluated with varying degrees of tonal and surface enhancements to reveal hidden details in vascularity, mucosal, and slight sub-mucosal variances. • Technology Truly Driving Care - PENTAX i-scan allows for enhanced imaging throughout the entire procedure, and has the ability to further enhance the lesion once it is identified. This multiple mode enhancement technology can truly reveal hidden colors of disease like never before. Here, PENTAX i-scan Mode 3 enhances the normal mucosal structures in the background, while highlighting a yellow region of the collapsed mucosal structure which pathology confirmed was a moderately differentiated adenocarcinoma.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
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.
Bulb / lamp failure
HighSymptoms: No light output, or dim/flickering output.
Root cause: Xenon or LED lamp module end-of-life.
Fan / cooling fault
MediumSymptoms: Overheat shutdown or thermal alarm.
Root cause: Cooling fan or vent obstruction.
Fiber optic cable wear
MediumSymptoms: Reduced light transmission, dim image at the scope.
Root cause: Fiber bundle damage from flex or connector wear.
Intensity control fault
LowSymptoms: Won't adjust brightness, stuck at one level.
Root cause: Control board or potentiometer fault.

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.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Bulb / lamp failure
- Confirm the presentation - typically no light output, or dim/flickering output.
- Check the most likely cause first: xenon or LED lamp module end-of-life.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the xenon / LED lamp module 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.
Symptom: Fan / cooling fault
- Confirm the presentation - typically overheat shutdown or thermal alarm.
