Test on Product Safety
This laser printer has the safety structure in compliance with IEC950, but there is still
concern of the electric shock due to the current leakage that may be caused if the
replacement work of maintenance parts was not implemented properly and accurately.
After the replacement and/or disassembling of the parts subject to the safety test described
in this document is completed, please confirm the safety requirements according to the
following procedures prior to powering on and carrying out the test drive.
1. Qualification of Test Operator: Skillful personnel having completed the appropriate
training program on the product safety.
2. Test Devices:
Insulation dielectric strength tester (500VA, Output 1500VAC) or,
Insulation resistance tester (500VDC, 100 M ohm)
3. Method of Measurement and Criteria of Judgment:
