Abstract
A message displaying area displays a message “DATA HAS BEEN RECEIVED”, which indicates that a print instruction has been received, as well as a message “CONDUCT AUTHENTICATION”, which urges a user to enter identification information. On the other hand, an input area displays a form in which a “username” and a corresponding “password” are to be entered. Specifically, a display presents an entry screen for identification information, including messages indicating that a print instruction has been received and authentication is required.
Claims19
An image formation apparatus connected to a power supplying device capable of supplying power via a data communication line, comprising:
- a control unit;
- a power conversion unit for converting external power received from an external power source into first drive power and outputting said first drive power;
- a separation unit for separating a communication signal and power flowing in said data communication line and outputting as second drive power the power thus separated;
- a communication unit for communicating data with an external device;
- a power supply unit for supplying at least one of said first drive power and said second drive power to said control unit and said communication unit;
- a switch, provided between said external power source and said power conversion unit, for opening/closing a power path in response to an instruction from said control unit;
- a manipulation unit for receiving an instruction input by a user to open/close said switch;
- and
- an authentication unit for performing an authentication process based on identification information input by the user,
- said control unit being operative to:
- drive said switch into a closed position, if an instruction for closing said switch is received from said manipulation unit while said switch is in an open position and if the authentication process by said authentication unit is done successfully, and
- urge the user to input said identification information to close said switch, if said communication unit receives a print instruction while said switch is in the open position.
A control method performed by an image formation apparatus connected to a power supplying device capable of supplying power via a data communication line, comprising the steps of:
- converting external power received from an external power source into first drive power and outputting said first drive power;
- separating a communication signal and power flowing in said data communication line;
- outputting as second drive power the power thus separated;
- receiving at least one of said first drive power and said second drive power to communicate data with an external device;
- receiving an instruction input by a user to open/close a switch provided between said external power source and a power conversion unit;
- performing an authentication process based on identification information input by the user;
- driving said switch into a closed position, if an instruction for closing said switch is received while said switch is in an open position and if said authentication process is done successfully;
- and
- urging the user to input said identification information to close said switch, if a print instruction is received while said switch is in the open position.
A storage medium storing a program used in an image formation apparatus connected to a power supplying device capable of supplying power via a data communication line,
- said image formation apparatus including:
- a processor;
- a power conversion unit for converting external power received from an external power source into first drive power and outputting said first drive power;
- a separation unit for separating a communication signal and power flowing in said data communication line and outputting as second drive power the power thus separated;
- a communication unit for communicating data with an external device;
- a power supply unit for supplying at least one of said first drive power and said second drive power to said processor and said communication unit;
- a switch, provided between said external power source and said power conversion unit, for opening/closing a power path in response to an instruction from said processor;
- a manipulation unit for receiving an instruction input by a user to open/close said switch;
- and
- an authentication unit for performing an authentication process based on identification information input by the user,
- when said program is executed by said processor, said program causing said processor to be operative to:
- drive said switch into a closed position, if an instruction for closing said switch is received from said manipulation unit while said switch is in an open position and if the authentication process by said authentication unit is done successfully, and
- urge the user to input said identification information to close said switch, if said communication unit receives a print instruction while said switch is in the open position.
