User Guide
RAM
The device contains two types of random-access memory (RAM):
●
One bank of nonvolatile RAM (NVRAM) stores parameters.
●
Dynamic random access memory (DRAM) provides temporary storage of the device program code
along with copy, scan, and print data.
Universal serial bus (USB) interface
The formatter receives incoming data through its USB interface. This interface provides high-speed,
two-way communication between the device and the host, allowing you to change device settings and
monitor device status from the host computer.
Control panel
The control panel consists of the following features:
●
groups of buttons to control copy and menu navigation
●
a 2-by-16 LCD display that shows status, menus, and messages
EconoMode
Select EconoMode to do the following:
●
enable the device to use less toner
●
extend the life of the toner supply
●
possibly reduce cost-per-page
NOTE Using EconoMode reduces print quality because the printed image is lighter.
HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, the toner supply
can outlast the mechanical parts in the print cartridge. If print quality degrades under these
circumstances, you must install a new toner cartridge, even if toner remains in the existing cartridge.
