At busy times, Help Desk staff will log off computers unattended for more than ten minutes. Do not deliberately introduce a virus nor take any action to circumvent, or reduce the effectiveness of, any anti-virus precautions established by IT Services. Always attend to printing. In particular, do not print long documents unattended on the dot-matrix printers.
Printer paper can fail to fold correctly, causing a mess on the floor or the printer to jam.
Also, always place unwanted output in the paper recycling boxes. Do not use the print station computers for anything other than printing. Children are only permitted in public computer rooms and areas under the supervision of an adult and must not cause a nuisance to other users.
