# USING TWO MACHINES TO REDUCE THE COPY TIME(TANDEM COPY)

## Overview

This function shares a copy job half-and-half between two machines connected to the network, enabling the reduction of the copy time.
Master machine and slave machine
The master machine performs only scanning, and a slave machine registered in the master machine performs only printing without scanning the original.

- To use this function, two machines must be connected to your network.
- Even if more machines are connected to the network, this function can only be used to have one other machine share a job.
- To configure the tandem connection setting, register IP address information of the slave machine in the master machine. For the port number, it is best to use the initial setting (50001). Unless you experience difficulty with this setting, do not change the port number. The tandem setting should be configured by your network administrator. If the master machine and slave machine will switch roles, configure the IP address of the master machine in the slave machine. The same port number can be used for both machines.
- In this situation:
  A saddle finisher is installed in the master machine while not installed in a slave machine.
  - Tandem Copy is enabled when specifying copies without stapling.
  - Tandem Copy is disabled when specifying copies with stapling.
- As shown here, if Tandem Copy is enabled using a function provided in the master machine and not provided in a slave machine, a message will appear.
- If a machine runs out of paper
  If either the master machine or the slave machine run out of paper, the machine that ran out of paper will hold the job while the machine that still has paper continues the job. When paper is added to the machine that ran out, the job resumes.
- If user authentication is specified
  - Tandem Copy is enabled when user authentication is specified in the master machine.
  - Tandem Copy is disabled when user authentication is specified in the slave machine while it is not specified in the master machine.
- If an odd number of sets is being made, one more set is output to the master machine.

To use Tandem Copy:
In "Setting mode", select [System Settings] → [Device Control] → [Tandem Connection Setting].

## Operation

Place the original and tap the [Preview] key.
Place the original in the document feeder tray of the automatic document feeder, or on the document glass.
When using the document glass to scan multiple original pages, change the original and tap the [Additional Scan] key.

- AUTOMATIC DOCUMENT FEEDER
- DOCUMENT GLASS

Tap the [Tandem Copy] key to uncheck it.
Tap the copies display key to specify the number of copies.
Up to 999 copies (sets) can be set. The specified number of copies are shared between the master and slave machines. If the number of copies is odd, the master machine makes more copies than the slave machine.
If an incorrect number of copies is set
Tap the [C] key and then enter the correct number.
Check the preview image in the preview screen.
Check whether or not settings produce the required results.
To cancel all settings:
Tap the [CA] key.
Tap the [Start] key to start copying.
When making only one set of copies, you do not need to specify the number of copies.
To cancel Tandem Copy:
