EconoMode
The EconoMode setting uses up to 50% less toner than standard mode printing by reducing the dot
density. However, using EconoMode does not extend the life of print-cartridge components.
Select EconoMode, which can be thought of as draft mode, from the control panel (PRINT QUALITY
menu) and through some software programs and printer drivers. The default setting is OFF.
CAUTION HP does not recommend full-time use of EconoMode. If EconoMode is used full-
time, it is possible that the toner supply will outlast the mechanical parts in the print cartridge.
NOTE EconoMode does not affect print speed or memory usage, or extend the life of the
print cartridge.
Input/output
The MFP receives print data primarily from the embedded HP Jetdirect print server. The MFP also
has a USB device port for connecting directly to a computer, and two USB host ports for connecting
third-party devices.
CPU
The formatter incorporates a 480 MHz RISC processor.
Memory
The formatter has 256 MB of on-board RAM.
NOTE If the MFP encounters a problem when managing available memory, a clearable
warning message appears on the control panel.
Hard disk
The MFP comes standard with a hard disk that has a capacity of greater than 40 GB. The hard disk
can permanently store fonts and forms, make multiple original prints, and accommodate job-storage
features.
Random-access memory
The random-access memory (RAM) contains the page, I/O buffers, and the font storage area. It
stores printing and font information received from the host system, and can also serve to temporarily
store a full page of print-image data before the data is sent to the print engine.
DIMM slot
Memory capacity can be increased by adding a memory DIMM to the formatter. Adding a memory
DIMM might also increase the print speed for complex graphics.
Firmware
The firmware is contained on NAND flash on the formatter. A remote firmware upgrade process is
available, which overwrites the firmware on the NAND flash.
