This is a product manual that introduces the features of the J-311S copier.
The manual begins with specifications and safety precautions, then describes the contents of the package, the appearance of the unit, and the functions of the control panel and indicator lights. Detailed instructions cover installation, wiring, loading thermal paper, and connecting telephone lines.
Subsequent sections explain how to prepare documents for faxing, select scanning resolution, dial numbers (including single‑key, hands‑free, and automatic redial), receive faxes, make phone calls, copy documents, and adjust function settings. The final chapters provide maintenance procedures, cleaning instructions for the print head and scanner, and simple troubleshooting tips. This manual is written in Chinese.
