Brother MFC-J6940DW A3 All-in-1 Inkjet Printer+Duplex Scan+Dual Tray #LC432 Ink

The Brother MFC-J6940DW A3 Colour Inkjet Multi-Function Printer is a powerful business-class All-in-One designed for offices that need genuine A3 printing, scanning, copying and faxing without moving to a large laser multifunction device. With fast print speeds of up to 28 ipm in both mono and colour, automatic duplex printing, single-pass 2-sided A3 scanning, dual 250-sheet paper trays and comprehensive wired and wireless connectivity, it is built for productive small and medium business environments.

A major advantage of the MFC-J6940DW is its versatile A3 paper handling. It provides 2 × 250-sheet lower trays, plus a 100-sheet multi-purpose tray, giving a total input capacity of up to 600 sheets. Its 50-sheet Automatic Document Feeder supports A3 documents and automatic two-sided scanning, making it particularly useful for contracts, plans, spreadsheets, reports and other multi-page business documents.

True A3 Business Multi-Function Capability

The MFC-J6940DW is much more than an A4 office printer that happens to print occasional A3 pages. It is designed as a genuine A3 business multifunction device with support for A3 printing, scanning, copying and faxing.

This makes it particularly useful for businesses working with large spreadsheets, construction or property documents, diagrams, schedules, posters, presentations, marketing materials and other documents that benefit from the larger A3 format.

Single-Pass A3 Duplex Scanning

One of the standout features of the MFC-J6940DW is its single-pass automatic two-sided scanning. The 50-sheet duplex Automatic Document Feeder can scan both sides of a document automatically, reducing the time required to digitise double-sided paperwork.

The ADF supports documents up to A3 size, making this particularly valuable for offices processing contracts, forms, invoices and other large-format multi-page documents.

Dual 250-Sheet Paper Trays + 100-Sheet Multi-Purpose Tray

The MFC-J6940DW provides excellent paper-handling flexibility with:

• ✔ Tray 1 – Up to 250 sheets
• ✔ Tray 2 – Up to 250 sheets
• ✔ Multi-Purpose Tray – Up to 100 sheets
• ✔ Total Maximum Input – Up to 600 sheets

The dual trays allow businesses to keep different paper sizes or media loaded simultaneously. For example, one tray can be configured for everyday A4 documents while the second tray is used for A3 paper.

Fast 28 ipm Mono & Colour Printing

Brother's MaxiDrive print technology enables the MFC-J6940DW to achieve print speeds of up to 28 images per minute in both black and colour. First Page Out Time is approximately 4.6 seconds for mono and 4.4 seconds for colour.

This combination of fast output and A3 capability makes the MFC-J6940DW particularly suitable for busy workgroups that need both everyday A4 printing and larger-format business documents.
