Usb Cover; Optimizing Printer Performance - Xerox WorkCentre EC7856 User Manual

USB Cover

To prevent users from accessing the USB port on the front of the printer, install the USB cover. While the
cover prevents physical access to the USB port, the port is still active. For details on enabling or disabling
USB ports, see the System Administrator Guide at www.xerox.com/office/EC78XXdocs.
You can find the USB cover and installation instructions in the compartment inside of tray 1.

Optimizing Printer Performance

Several factors influence printer performance, including temperature, humidity, air pressure, and the
chemical characteristics of the paper and coatings. The printer must form an electrostatic image on the
paper, which depends on the ability of the air to hold and transfer electrical charges. The paper and
coatings must hold an electrical charge in the areas where the toner must adhere.
To optimize the performance of your printer:
At the printer control panel, press the Machine Status button, then touch the Tools tab.
