General Information 1-17
Rear Panel
Connectors
The rear panel (Figure 1-12) of the printer features the host interface
connectors to the printer; it includes the following connectors:
• Standard parallel (high-density connector), IEEE 1284C
• Twisted Pair (10BaseT) Ethernet connector
• Universal Serial Bus port
• A special 5-pin connector accommodates a service RS-232 cable
from a PC running PC-based diagnostics.
The rear panel also includes two option slots. With the addition of an
optional Ethernet Interface network card in the lower slot, the printer
can support 10Base2 or 100BaseT Ethernet connectors.
NOTE: When an optional Ethernet Interface card is installed, the
printer’s built-in 10BaseT Ethernet port is disabled.
The second slot accommodates an internal IDE hard drive for print
DICOM support.
Health LEDs
Two health LEDs indicate the status of the printer’s CPU functions:
PostScript (PS) processing and Print Engine (PE) control.
• Blinking: The printer is operating normally. Both LEDs blink
irregularly during diagnostics. To indicate the printer passes
the POST tests and is operating normally, the left (PS) LED
flashes in a “heartbeat” rhythm (on 0.5 seconds, off 0.5
seconds). The right (PE) LED pattern is two quick flashes on,
then off for a count of two for a total cycle time of just over two
seconds.
If a soft error occurs, image processing occurs, but in a reduced
capacity. Soft errors include failure of expansion memory
DIMMs or of any of the interface ports. When a soft error
occurs, the printer automatically prints a startup page listing
the error.
• On or Off, or blinking a coded error indication: A hard error
condition has occurred that would keep the image processor
board from operating. Refer to the topic “Error Codes and
Messages” for the meaning of a coded indication.
