Endoscope Troubleshooting 

• Endoscope will not fit into processor

  Endoscope will not fit into processor
  Possible Causes Soaking cap has not been removed. Video pins on scope have been bent. Video processor receptacle has been damaged Light guide prong is bent 90i series scopes are not backwards compatible with the EPK-700 and EPK-1000 processors
  Possible Solutions Ensure soaking cap is removed from scope Do not force scope into processor. If pins have been bent, send scope in for repair Gently try to insert another scope into the processor. If the problem persists, your processor is likely damaged. Send it in for repair Follow same procedure as #3 above. If the second scope fits into the processor without a problem, the light guide prong on the first scope is likely bent. Send scope in for repair Use a compatible model of endoscope

• Angulation not working properly

  Angulation not working properly
  Possible Causes Angulation locks are on Angulation wires are damaged
  Possible Solutions Ensure angulation locks are in the off position Send scope in for repair

• Endocope will not blow air or water, or the pressure of the air/water flow is inadequate

  Endocope will not blow air or water, or the pressure of the air/water flow is inadequate
  Possible Causes Pump on processor is not turned on Water bottle is not properly connected to processor Lever on water bottle is in the drain (down) position A/W feeding tube (from the water bottle) is not connected to scope Water-bottle is empty Water-tight integrity of water bottle has been compromised O-Ring(s) missing or damaged on water bottle O-Ring(s) missing or damaged on the air/water valve Air/Water channels are clogged (fully or partially)
  Possible Solutions Turn processor pump on Ensure that water bottle is properly pushed into opening on left side of processor In this case, you may find that the scope will blow air, but not water. Position the lever in the A/W (up) position to activate both the air and water functions Connect the A/W feeding tube from the water bottle assembly to the A/W port on PVE connector Fill water-bottle with water Ensure that the water bottle is not cracked and the top is properly connected to the bottom of the bottle Ensure that there is an undamaged o-ring on the water bottle connector, which plugs into the processor, and also on the threaded neck of the water bottle Ensure that the o-rings on the air/water valve are installed properly and are not damaged If proper pre-cleaning is being performed after each procedure, there is a very low probability of this occurring. After asuccessful leakage test, soak endoscopein warm enzymatic detergent for 30 minutes. After soaking, attempt to flush airand water channels using a syringe andappropriate cleaning adapters. Caution: excessive force during this process can cause further damage

• Dry leakage test fails (pressure gauge needle ON)

  Dry leakage test fails (pressure gauge needle ON)
  Possible Causes Scope has a large leak Leakage Tester is not working properly
  Possible Solutions Contact your local PENTAX representative or the PENTAX Service Centre to determine the next step. Do NOT proceed with the wet leakage test, cleaning, or disinfection until you know that it is safe to do so. The scope will need to be sent in for repair Test the leakage tester - remove it from the scope, close the valve, occlude the tubing (by pinching it), and pump the tester into the green test area. If the tube is fully occluded, the leak tester will hold the pressure. If the tube is fully occluded and the gauge still drops, either the valve is not shut or the leakage tester is not functioning properly. Repeat the same process with a new leakage tester

• Wet leakage test fails (bubbles are observed coming out of the endoscope)

  Wet leakage test fails (bubbles are observed coming out of the endoscope)
  Possible Causes Scope has a small or large leak
  Possible Solutions Immediately remove your scope from the water. Contact your local PENTAX representative or the PENTAX Service Centre to determine the next step. Do NOT proceed with cleaning or disinfection until you know that it is safe to do so. The scope will need to be sent if for repair.

• Air/water or suction valve is sticking.

  Air/water or suction valve is sticking.
  Possible Causes O-ring(s) on valve have dried out O-ring(s) is/are damaged The valve or the valve housing on the endoscope is bent
  Possible Solutions Lubricate valves with silicone according to PENTAX recommendations. Be careful to lubricate only the o-rings and also to not over-lubricate. Inspect o-rings to ensure that they are not damaged. Replace if necessary Try another lubricated valve in the scope to see if it also sticks. You should be able to determine if the valve or the valve housing on the scope is the problem. If it is the valve housing, the scope should be returned to a PENTAX service centre for repair

• Forward water jet not functioning properly (either not flowing or back-flowing)

  Forward water jet not functioning properly (either not flowing or back-flowing)
  Possible Causes Forward water-jet channel is clogged Endo-irrigator pump not turned on or improperly connected (if applicable) Endo-irrigator water bottle is empty Forward water jet check valve is either damaged or improperly installed (this will cause back flow of fluid into tubing)
  Possible Solutions If scope passes a leakage test, follow same procedures for clearing channel as described in the air/water channel section above Ensure that endo-irrigator pump is turned on and all components are properly connected. Ensure endo-irrigator water bottle is full Inspect forward water-jet check valve to ensure that it is properly installed, and not damaged

• Resistance when passing an accessory through biopsy channel

  Resistance when passing an accessory through biopsy channel
  Possible Causes Biopsy channel is clogged Biopsy channel is kinked
  Possible Solutions Ensure that biopsy channel is not clogged. If scope passes a leakage test, follow same procedures for clearing channel as described in the air/water channel section above If the above does not eliminate the resistance, the biopsy channel is likely kinked. Send scope in for repair in order to avoid any further damage
