A system administrator was having a lot of trouble with a network router. Strange error numbers such as "E6" and "B2" were showing up on the display. So he called the manufacturer and got connected to field service.

Sysadmin: "Can you tell me what error code E6 means?"

Technician: "Communications line 6 has a short in it."

Sysadmin: "Where's that documented?"

Technician: "In the technical reference manual."

Sysadmin: "We're having a lot of problems here, could you fax me a copy of that manual?"

Technician (reluctantly): "Well. OK. But it's my only copy, so you'll have to promise to fax it right back to me."
