Most printers used in La Cañada Unified facilities utilize a laser printing process rather than the more consumer-oriented inkjet printers. Laser printers utilize an electrostatic process of passing a laser over a negatively charged drum to attract a charged powder-based ink, called toner, onto the paper. The toner is then heated to permanently fuse the print. Toner is sold in cartridges, and must be replaced as it runs out.
We have moved most printers over to our managed print service where toner auto-ships. If you see your printer running low, you can put in a ticket to make sure one is on the way to you. Also, there is a phone number on the printer. You can call that to check as well.
