📝 Product Description

The GC Original LAN Card – Part No. QM7-6778 is a replacement network board (also called LAN board, Ethernet board or wired network interface card) for the Canon PIXMA MegaTank GM4070 monochrome ink tank printer.

The GM4070 supports a wired LAN connection (10/100 Ethernet). This board provides that connection, letting offices print and scan over a network cable instead of relying on Wi-Fi or USB.

A faulty LAN card can cause:

• Printer not detected on the wired network
• Ethernet port with no link light or no connection
• Network printing or scanning failing while USB still works
• IP address not being obtained or dropping out
• Network errors after a power surge or cable fault

Replacing the board restores stable wired network printing.

Value For Money: pulled from a working printer and tested before dispatch.

Ideal for printer technicians, service centers, dealers and offices.
