If you transported your printer over a long distance, you need to adjust the color registration for possible misalignment.
Follow the steps bellow to adjust the alignment of the color registration.
1.Make sure the LCD panel displays Ready, then press the 
Enter button to access the control panel menus.
Note:
You may not be able to adjust the color registration when the printer is in the sleep mode or when any error has occurred even if you can select the item from the menu on the control panel.
2.Press the d Down button several times until the LCD panel displays Color Regist Menu, then press the 
Enter button twice.
You can print files in the USB memory via a USB Host interface without starting the computer, installing the printer driver, or connecting the printer to a network.
Note:
❏If the USB Host setting on the control panel is set to OFF, this function cannot be used. Confirm the setting is set to ON in advance.
❏If the printer is in the sleep mode, the USB memory may not be detected automatically. In that case, press any button on the control panel.
❏We recommend using a USB memory that has less than 2 GB of memory. Accessing USB memories that have more than 2 GB of memory may take too long.
❏If a large numbers of files are in the USB memory, accessing the USB memory may take too long.
❏If accessing the USB memory takes too long, try formatting it to improve the access speed.
The printable file formats are JPG, TIF, PS, PDF. You can also print EPN formatted files created from the applications like MS Word or MS Excel by using USB Memory Print Maker, which is included in the printer software
Note:
The EPN formatted files created by USB Memory Print Maker are printed in High Quality (Printer) mode regardless of the Printer Mode setting in the Extend Settings tab on the printer driver.
