After finishing installation, you can check whether the duplex unit is properly installed by printing the configuration page from the [List/Test Print] menu. If it is installed properly, you will see "Duplex Unit" as " Attached Equipment " on the configuration page.
If the duplex unit is not installed properly, repeat the procedure from the start. If you cannot install it properly even after reinstallation, contact your sales or service representative.
If the printing position is not correct, adjust the registration of the trays. For more information about adjusting the registration of the trays, see Adjusting Printing Position.
When the duplex unit is installed, the rear cover is no longer required. However, we recommend you keep the cover for future use.
For details on printing the configuration page, see Test Printing.
