The printer’s I C bus An internal data bus, called the I C bus, connects all I/O boards to the main board. Through this single bus, the main board can “poll” the I/O boards for the state of the printer’s sensors as well as actuate the printer’s solenoids. This data bus greatly simplifies the wiring that would otherwise be required for monitoring numerous sensors and solenoids.
The system consists of a vacuum pump assembly, the cap/wipe/purge assembly and the cap/wipe/purge carriage drive.

The actual position of some printer assemblies, such as the Caution printhead or the cap/wipe/purge assembly, cannot be ascertained at all times. The printer records, in NVRAM, where it last positioned such assemblies each time it moves them. If, after power-down or a power interruption, the assemblies are manually repositioned, the printer erroneously assumes that the assemblies are in the position it last left them.

Network Event Logs Phaser 850 The Phaser 850 printer maintains three logs in memory detailing network functions. The logs contain TCP/IP and Netware initialization landmarks and limited print-time processes. The log also shows the state of the networking hardware. The logs are useful for troubleshooting network setup problems and isolate network problems from printer problems.
If an error is detected, the Phaser 850 printer flashes the front panel Error LED with a repeating error code pattern as well as the rear panel PS LED. On the Phaser 840 printer, the pattern is displayed only on the rear panel PS LED (left side of the DIP switches).
Page 93
The front panel indicates the printer is in a clean cycle. If the printer senses ink or debris on the drum, a drum cleaning page is printed (Phaser 840 printer only). The temperature of the printhead, drum and paper preheater are allowed to stabilize at their operating temperatures and ink is melted if needed.
Page 94
This test takes about 8 seconds. All LEDs are off during the test. If POST diagnostics pass, the front panel displays the Xerox logo. If an error is detected, the error message is displayed on the LCD and the printer flashes the LEDs with a repeating error code pattern.
