Timeout Function for Copier Control Device
Described is a timeout feature in a copier controller that automatically
disables a copier after a predetermined period of nonuse.
A copier control device interfaces a copier and a host computer. To gain
access to a copier, a user either enters a badge using the badge reader on the
device or enters an account number using the keyboard. After the user is
finished using the copier, he is expected to push a button on the device
keyboard, signalling that the copier transaction is complete.
Often, however, users will forget to push the end-of- transaction button when
they are finished. If they do so, subsequent users can use the copier without
going through the access step. This will cause the subsequent user's copies to
be charged to the previous user.
Therefore, a timeout feature is included in the device to minimize
occurrences of the problem. The device monitors the various signal lines from
the copier and detects that a period of nonuse has occurred. At that time, the
device automatically terminates the transaction and returns to its dominant mode.
Occasionally, a paper jam or other occurrence in the copier will cause
operator intervention which may exceed the timeout period set in the device. To
prevent the device from timing-out prematurely when this occurs, an additional
signal line is included in the interface from the copier to the device which inhibits
timeout when active.
