Misfed

"Can you get somebody to have a look at that printer? I don't understand why it keeps jamming," says T.Aldous.

A clue affords itself. Frog has just sent a long report to be printed out. Barely had it started when T.Aldous came out of his office for to go out to a meeting, stopped by the printer, opened the paper tray and took out a handful of sheets.

This despite my having put a notice up there saying:

Do not remove paper from the paper tray while the printer is in use. This causes paper jams and should be avoided.
