Abstract
A paper tray access system for a printer includes a locking cover of paper tray, an authentication device, a weight sensor located beneath the paper tray, a printer display, a computing device including electrical circuitry, a memory storing program instructions and at least one processor. The computing device is configured to receive user input from the authentication device and determine whether the user input matches the authentication record. When user input matches authentication record, the computing device presents a selection on printer display to access a paper tray, receives the selection, records a first weight of the paper tray upon receiving the selection, unlocks the locking cover, records a second weight of the paper tray, calculates an amount of papers removed from paper tray when second weight is less than first weight, and calculates an amount of papers added to paper tray when second weight is greater than first weight.
