Photocopier supplier Canon is warning customers to take better care of their office equipment during the Christmas period, claiming that the festive season traditionally leads to a 25 per cent hike in service calls due to incidents such as the classic backside copying prank.

Such a stunt, a popular mainstay of the office party, often results in cracked glass on the copier, with 32 per cent of Canon technicians claiming to have been called out to fix glass plates during the Christmas period after attempts to copy body parts went wrong.

Geoff Bush from the north of England said one case he’d attended, where a young lady had cracked the glass mid-scan, also jammed the scanner so that it wasn’t until the machine was fixed and her colleagues all sober that copies of her backside starting pouring from the machine.

Just a warning before you attend any holiday parties. We want you all to be safe and sound. Including the sexy bits.
