settings, downloaded fonts, and macros. The default setting is for Sleep Mode to be enabled, and the
product enters Sleep Mode after a 30-minute idle time.
The product exits Sleep Mode and enters the warm-up cycle when any of the following events occur:
●
A print job, valid data, or a PML or PJL command is received
●
A control panel button is pressed
●
A cover is opened
●
A paper tray is opened
●
The engine-test switch is pressed
NOTE: Product error messages override the Sleep message. The product enters Sleep Mode at the
appropriate time, but the error message continues to appear.
TIP: When the product is in Sleep Mode, the sub power supply is off and the low-voltage power
supply is on. The scanner can not be used when the product is in Sleep Mode.
Input/output
The product has three I/O interfaces:
●
Hi-Speed USB 2.0
●
10/100/1000 Ethernet LAN connection with IPv4 and IPv6
●
Easy-access USB printing (no computer required)
CPU
The formatter incorporates an 800 MHz processor.
Memory
The random access memory (RAM) on the formatter printed circuit assembly (PCA) 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.
NOTE: If the product encounters a problem when managing available memory, a clearable warning
message displays on the control panel display.
Firmware
The hard disk drive (HDD) or solid state module (SSM) store the firmware. A remote firmware
upgrade process is used to overwrite and upgrade the firmware on the HDD or SSM.
Nonvolatile memory
The product uses nonvolatile random access memory (NVRAM) to store device and user
configuration settings. The contents of NVRAM are retained when the product is turned off or
disconnected.
