Troubleshooting Chart
The following instrument troubleshooting chart lists possible problems relating to
electrical and mechanical operations that could occur during instrument operation.
Probable causes and recommended corrective actions are also included, so that many
isolated problems can be quickly corrected. When dealing with any problem with the
Hematek Slide Stainer, it is essential to determine which portion of the system is the
source of the trouble. A systematic approach should be employed to isolate the problem.
If additional assistance is required concerning an instrument problem, copy and complete
the Hematek Preservice Checklist in Appendix A, and contact your local technical support
provider or distributor.
Only Hematek Stain Paks should be used with the Hematek Slide Stainer. Do not use any
other stain solution. For problems or questions concerning the Stain Paks, contact your
