Multi-function printer and intuitive document alignment method thereof

An intuitive document alignment method, suitable for a multi-function printer (MFP), the intuitive document alignment method comprising:

• defining a document alignment original point, a first document alignment boundary which originates at the document alignment original point and extends along a first direction, and a second document alignment boundary which originates at the document alignment original point and extends along a second direction on a scan platform of the MFP, wherein the first direction and the second direction are perpendicularly intersected;
• installing a first touch strip light-emitting diode (LED) module on the first document alignment boundary and installing a second touch strip LED module on the second document alignment boundary;
• and
• when a top cover of the MFP is opened, controlling the first and the second touch strip LED modules to respectively generate a first predetermined lighting line and a second predetermined lighting line, wherein the first and the second predetermined lighting lines define a default scan area.

A multi-function printer (MFP), comprising:

• a top cover;
• a control unit, configured to be served as an operation core of the MFP;
• a scan platform, having a first document alignment boundary and a second document alignment boundary which are perpendicularly intersected;
• a first touch strip light-emitting diode (LED) module, coupled with and controlled by the control unit, and installed on the first document alignment boundary;
• and
• a second touch strip LED module, coupled with and controlled by the control unit, and installed on the second document alignment boundary,
• wherein the control unit is further configured to control the first and the second touch strip LED modules in response to the top cover being opened to respectively generate a first predetermined lighting line and a second predetermined lighting line, wherein the first and the second predetermined lighting lines define a default scan area.
