7-6 Troubleshooting AXIOM™ 400 Product ManualAccu-Sort Systems, inc. 07-AXIOM400-Troubleshooting_R10.docTroubleshootingThe following PCS (problem/cause/solution) tables are designed to assist you introubleshooting the more common events that may occur during installationand operation of your Axiom Bar Code Scanning Solution.Table 7-6: PCS TroubleshootingProblem The POLARITY LED in the wiring base is RED.Cause(s) Wiring from the power supply to the INPUT POWER terminalblock is incorrectly wired.Solution(s) IMPORTANT: DO NOT install the scan head if polarity LED is RED.1. Correct the polarity problem by swapping the wires at theINPUT POWER terminal block.2. Confirm power polarity is correct (GREEN LED).3. Install the scan head. (See page 3-16.)Problem There is no laser light exiting from the Axiom when poweris activated.Cause(s) No power is provided to the Axiom.Solution(s) 1. Check to ensure power is properly connected.2. Check to see if Axiom Status LED turns ON.3. Confirm power supply functioning.4. Remove Axiom scan head from wiring base.5. Verify Power LED in wiring base is GREEN. (See Figure 7-2.)6. If Power LED is RED, polarity is swapped.7. If Power LED is OFF, check wiring at the INPUT POWERterminal block.8. Replace the power supply if wiring was correct.9. Reassemble Axiom scan head to wiring base.Problem The Axiom is not reading bar codes.Cause(s) Code type is not enabled or wrong code length.Code passes by at too large an angle (tilt, pitch, skew).All codes have very poor print quality.Solution(s) 1. Enable code type or correct code length.2. Make sure Axiom laser beam is ON when code passes by.3. Verify correct bar code parameters are enabled.4. Enable TEST MODE. (Use either the Axiom control panelbutton or Axcess Tools > Axiom Commands > Test Mode On.)5. Hold code in the scan line.6. Verify the Axiom is reading the code.7. Correct any tilt, pitch, or skew problems.8. Remedy bar code printing problems.
