The library has photocopiers available for self-service copying. Copiers are located on the 1st, 2nd, and 3rd floor lobbies (black and white only).
The self-service photocopiers will accept cash or your CatCard and cost $0.10 per page with cash or $0.08 per page using a CatCard.
Unfortunately, your $7.50 of free printing cannot be used for copiers. You can add regular money to your CatCard at their office or online.
Another option is to use one of the KIC scanners in the 1st floor stairwell to scan your document and email it to yourself for free.
