On the [Maintenance] tab, you can adjust color registration and print starting positions.
Normally, you do not have to adjust registrations. However, adjustments could be useful in some cases, especially when you want to print in a specific position. Under [Registration: Tray 2 Paper], you can adjust the print image position printed on the sheet fed from tray 2. To check the adjustment result, use [Print Test Sheet].
Also, you can updated the firmware by clicking [Printer Firmware Update].
The latest version of the firmware can be downloaded form the supplier's website.
