1. Recommended maintenance schedule
| Interval | Tasks | Who |
|---|---|---|
| Daily | Visual check of drawer, slot and interlock. Confirm a test cycle reports success and field strength. Check ventilation is clear. | Operator |
| Weekly | Clean the media path and drawer rails. Verify the LCD is readable and the cycle counter is incrementing. Check the power cable and plug for damage. | Operator / site IT |
| Monthly | Check cooling fan operation and dust build-up. Confirm the room is within the datasheet's temperature and humidity range. Review the destruction register for gaps. | Site IT |
| Quarterly | Inspect capacitor charging behaviour under load. Verify the interlock safety function. Check all cable and connector integrity. Review spares held on site. | Site IT / engineer |
| Half-yearly (high volume) | Field-strength verification with a calibrated instrument. Full mechanical service of drawer, slot and hinges. | Authorised engineer (AMC) |
| Annual | Full service per manufacturer guidance, capacitor health assessment, calibration/verification certificate issued, training refresher for operators. | Authorised engineer (AMC) |
| After any relocation | Field-strength verification before returning the machine to service. | Authorised engineer |
2. Daily and weekly checks in detail
Daily, before the first batch:
- Run a cycle with a known test medium and confirm the LCD reports success and, on the T-1.2, T-1.5, T-4 and T-5, the expected field strength.
- Note the reading in the destruction register. A drifting baseline is the earliest warning you will get.
- Check the drawer or slot closes cleanly and the interlock engages without forcing.
- Confirm nothing is blocking the ventilation openings.
Weekly:
- Clean media dust and metal particles from the drawer and the entry slot — metal swarf near a high-field coil is worth keeping out.
- Check the cycle counter has incremented as expected for the volume processed.
- Inspect the power lead, plug and any extension for heat discolouration.
- Confirm the machine's location is still controlled — access to a degausser is access to a sanitisation capability.
3. Quarterly tasks
- Capacitor charging test. Confirm the bank reaches and holds its rated voltage under load. A slow charge or a voltage that sags quickly is an early capacitor failure.
- Interlock function test. Confirm the machine will not pulse with the drawer open or the slot obstructed.
- Cooling. Clean filters and fan housings. In Indian ambient conditions this is the most common preventable fault.
- Environment check. Log the room temperature and humidity. The datasheet limits matter, and Indian summers are unforgiving in a non-air-conditioned store room.
- Register review. Sample the destruction register against the asset register. Gaps in the sequence are what auditors find first.
- Spares. Confirm you hold the consumables and spares recommended for your model.
4. Annual service and verification
The annual visit is the one that produces your audit evidence. It should include:
- Full mechanical and electrical service per the manufacturer's guidance.
- Field-strength verification with a calibrated instrument, with the reading recorded against the machine's specification.
- A signed verification / test certificate for your records.
- Capacitor bank health assessment, with a recommendation on remaining life.
- Interlock and safety function re-verification.
- Operator refresher training, with training records issued.
- A written report with findings, and a quotation for anything needing replacement.
Keep the certificate. It is the document that lets you answer "how do you know your degausser is still effective?" — a question that is being asked more often every year, particularly in banking and government environments.
5. Common failure modes
| Symptom | Likely cause | Action |
|---|---|---|
| Cycle runs but field reading has dropped gradually | Capacitor bank degradation | Stop relying on the machine for sanitisation; arrange service. Do not continue producing destruction records. |
| Machine does not complete a cycle, "Go" indicator absent | Interlock not closed, or a parameter out of tolerance | Check the drawer/slot is fully closed. If the parameter fault persists, stop and call for service — the interlock is doing its job. |
| Intermittent trip on the supply | Overloaded or shared circuit; cable degradation | Move the machine to a dedicated earthed circuit. Inspect the cable. |
| Overheating or fan noise | Blocked vents, dust, high ambient temperature | Clean, improve airflow, check room temperature against the datasheet. |
| Drawer stiff or media will not seat | Misalignment, debris, worn rails | Clean and check alignment. Persistent stiffness needs mechanical service. |
| LCD or cycle counter not working | Electronics fault | Service. The machine can still degauss, but without the display you lose your per-cycle evidence — treat it as out of service for compliance purposes. |
| Flickering or unstable field reading | Loose connector, earth fault, or power quality | Check the supply and earth. Have the machine verified. |
6. Storage, transport and environment
- Room. Dry, ventilated, within the datasheet's temperature and humidity range, and access-controlled. A non-conditioned store room in an Indian summer is the most common environment-related cause of capacitor and cooling faults.
- Dust and metal. Keep the media path clean. Metal swarf near a high-field coil is a genuine hazard.
- Power. Dedicated earthed circuit. Avoid long daisy-chained extensions. Consider running the machine on the same conditioned supply as your server room rather than an unstable branch.
- Moving the machine. Capacitor banks can retain charge. Transport should be by a service engineer. After any relocation, field-strength verification is required before the machine returns to service — this is a condition of warranty on most models.
- Deployment cases. The rugged wheeled cases for the T-1, T-1.2, T-1.5, T-4 and T-5 are for transport and field use. Verify field strength after transit.
7. Maintenance records to keep for audit
- Machine make, model and serial number
- Date of every service visit and the engineer involved
- Field-strength verification readings and the specification they were checked against
- Test / calibration certificate issued
- Parts replaced, with part numbers
- Operator training records with dates
- The destruction register, showing per-cycle verification values
- Any incident where the machine was out of service, with the period affected
