A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.
Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

Is one of the link lights ON (solid green)?
10 light 100 light
Check the link lights on your print server; these lights are built into the network connector. One of the link lights -- either the 10 light or the 100 light, but not both -- should be ON solid green (not blinking), to indicate a valid network connection. Is either the 10 light or the 100 light ON solid green?
