Sakura Tissue-Tek TEC 5
Sakura · Model Tissue-Tek TEC 5
Embedding system The Tissue-Tek TEC 5 Tissue Embedding Console System consists of two modules that together create an ergonomic workstation for the production of paraffin blocks. The user can position the individual modules from either left to right or right to left, depending on personal preference. The work surfaces of both modules are at the same height and thus the specimens can be transferred easily from one side to the other. The system is fully programmable, with automatic start-up and shutdown capability and precise temperature control of all areas. The capacity of the workspace is 10 cassettes at each side of the dispensing control unit. An electric forceps can be connected easily and placed in one of the six heated wells (to prevent paraffin sticking to the forceps).
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Zone temperature not holding
HighSymptoms: Paraffin reservoir, work surface, heated wells or cold plate off set point; blocks embed poorly.
Root cause: Failed heater element or cold-plate cooling, a temperature sensor drift, or a control fault.
Paraffin dispensing fault
HighSymptoms: No or weak paraffin flow, foot-switch dispense not working, drips.
Root cause: Clogged paraffin filter/strainer, a stuck dispense valve, or wrong melt temperature for the paraffin in use.
Cold plate not reaching -5 C
MediumSymptoms: Blocks do not set firmly, long cool time.
Root cause: Peltier/refrigeration degradation or a fouled heatsink/fan.
Heated forceps well / electric forceps fault
LowSymptoms: A heated well cold, paraffin sticking to the forceps, forceps not heating.
Root cause: Failed well heater or the electric-forceps connection.
Automatic start-up / shutdown timer fault
LowSymptoms: Console does not warm up or shut down on schedule, program lost.
Root cause: Real-time clock / control-board fault or a software issue.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Paraffin will not dispense
- Confirm the reservoir is full and its melt temperature matches the paraffin actually in use.
- Clean or replace the paraffin filter / strainer.
- Test both manual and foot-switch dispense.
- Clear the dispense valve and nozzle if flow is still blocked.
- Verify steady, adjustable flow before returning to service.
Symptom: A heated zone off temperature
- Identify the zone and compare displayed vs set value.
- Power-cycle and check for a software update.
- Measure the zone with a reference probe.
- Isolate heater element vs sensor vs board with resistance checks.
- Replace the failed part and re-verify all zones and the cold plate.
