General Troubleshooting
Network Problems
The printer maintains 6 logs in memory detailing network functions. The logs
contain TCP/IP, NetWare and AppleTalk initialization events. The logs can
also be accessed remotely via CentreWare.
The logs list events chronologically. The log is limited in length; when the log
is full the printer stops recording data to the log. The logs are stored on the
Hard Drive so only new data is stored each time the printer’s power is cycled.
There is a Connection Setup page, Configuration page, and a network reset
available for troubleshooting network problems.
Print an Event Log or Runtime Log:
1. Enter normal ‘Customer Mode’.
2. From the main menu, select Troubleshooting and press OK .
3. Scroll and select Network Log Pages and press OK .
4. Highlight the appropriate menu item from the list and select OK .
Note
Phaser 8500/8550/8560 printers include diagnostic tools for network
connections. Use the menu path
Troubleshooting > Network
Problems > Network > Diagnostics . To troubleshoot network problems,
select the standard Network Log Pages or Network Diagnostics. Network
Diagnostics take about 60 seconds to test the network connection for
basic communication problems such as collisions, wrong ethernet
speeds, possible missing hubs when not using crossover cable, and
inappropriate IP settings for the network type detected or server.
5. The page should now print.
Note
To print the Connection Setup Page or Configuration Page , select the
Printer Setup Menu.
Obtaining Serial Back Channel Trace
In rare cases the printer may exit unusual behavior that is difficult to
troubleshoot. In such cases, if feasible, it can be useful to obtain a Back
Channel Trace from the printer’s on-board serial port. The Back Channel
Trace, lists step-by-step what the printer is doing up to the point that an error
occurs. The trace may offer clues to help troubleshoot the problem. You will
need the following:
■ Computer with a serial port
■ Null modem serial cable
■
Serial cable adapter, part number 600T80374 (Same adapter used to run
PC- based diagnostic on other Phaser printers.)
