This document describes safety information for the 7300 Series All-In-One, including power supply information and connection information.
This manual begins with safety information, such as using only the supplied power supply and avoiding fax use during lightning storms, followed by unpacking instructions and preparing the All‑In‑One unit.
Subsequent sections cover language and region setup, connecting telephone lines, loading paper, installing print cartridges and software, and a troubleshooting guide for common issues like a non‑lit power indicator or incorrect display language. This manual is written in Chinese.
Disconnect the power cord from the wall outlet, reconnect it fully into the All‑In‑One, try a different outlet, and press the power button.
Only the power supply provided with the product or a manufacturer‑authorized replacement may be used.
Do not use the fax feature during a lightning storm and avoid making any electrical connections.
