Phaser 840 Color Printer
Rear panel
Connectors
The rear panel 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
■
A Universal Serial Bus port
■
Optional SCSI high-density connector (hard disk drive or Tektronix
approved scanner).
■
A special 5-pin connector accommodates a service RS-232 cable from a
PC or Macintosh computer running PC-based diagnostics.
The rear panel also includes two option slots. With the addition of a PhaserShare
network card in one slot, the printer can feature either of these connector
combinations:
■
LocalTalk connector
■
ThinNet (10Base2) and Twisted Pair (100BaseT) Ethernet or Token Ring
connectors.
Note
When an Ethernet or TokenRing PhaserShare card is installed,
the printer’s built-in 10BaseT Ethernet port is disabled.
The second slot accommodates an internal IDE hard drive for print job collation,
job accounting, font storage and PDF direct printing.
Health LEDs
Two health LEDs indicate the status of the printer’s CPU functions: PostScript
processing and print engine control.
■
Blinking
: The printer is operating normally. Both LEDs blink
irregularly during diagnostics.
If a soft error occurs, image processing occurs, but in a reduced capacity.
Soft failures include failure of expansion memory DIMMs or 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” on page 25 for the
meaning of a coded indication.
