# USING TWO MACHINES TO COPY IN PARALLEL (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. Tandem Copy must be enabled in [Tandem Connection Setting] of setting mode.

Master machine and slave machine
The master machine is a machine used to scan originals and print the data. The slave machine is registered in the master machine, and only print data without scanning originals.

- To use this function, two machines must be connected to your network. You cannot use three machines or more for Tandem Copy.
- If Tandem Copy is enabled using a function provided in the master machine and not provided in a slave machine, a message will appear. For example, if 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.
- 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 you have configured the user authentication settings, Tandem Copy may not be enabled depending on authentication specified for the master and slave machines.
  - 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 (administrator)", select [System Settings] → [Device Control] → [Tandem Connection Setting].

- IP address information of the slave machine must be registered 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.

###### To prohibit tandem transmission or reception:

In "Setting mode (administrator)", select [System Settings] → [Device Control] → [Tandem Connection Setting].

- To prohibit tandem transmission enable [Disabling of Master Machine Mode].
- To prohibit tandem reception, enable [Disabling of Slave Machine Mode].
