The guide starts with unpacking the printer, checking that all components are present, and connecting the power and telephone lines. It then walks you through loading paper, installing the four ink cartridges (black, cyan, magenta, yellow), and performing the initial print‑quality check.
Subsequent sections cover configuring the device’s settings such as receive mode, LCD contrast, date and time, personal information, and audio/pulse dialing mode. It also explains how to connect the printer via USB, wired Ethernet or wireless, install the MFL‑Pro Suite and BRAdmin Light utilities, and restore network defaults. Finally, it provides instructions for replacing consumables and troubleshooting ink‑related errors. This manual is written in Chinese.
