Duplexer / Duplexing Device
A mechanical device that enables automatic double-sided scanning or printing.
Detailed Explanation
A duplexer is the hardware component that enables automatic duplex (double-sided) printing or scanning. For printing, the duplexer pulls paper back into the machine after printing one side, flips it, and feeds it through again to print the second side. For scanning, a duplex ADF (DADF) can scan both sides either in a single pass or by mechanically reversing the page. Automatic duplexing saves time, reduces paper consumption by 50%, lowers costs, and improves environmental sustainability. Most modern business copiers include automatic duplexing as standard equipment.
Examples
- Single-pass duplex: Scans both sides simultaneously
- Two-pass duplex: Reverses page for second scan
- Automatic duplex printing: No manual flipping required
