  • Publication number: 20150029538
    Abstract: A multifunction peripheral includes: a facsimile communication section, an image memory, a job management section, a transfer instruction reception section, a password creation section, a data transfer control section, and a delete instruction reception section. When the delete instruction reception section has received a delete instruction, the job management section compares a password indicated by the delete instruction with a password created in correspondence with facsimile data of a fax job targeted for deletion by the delete instruction, and deletes the fax job indicated by the delete instruction under condition that the passwords agree with each other.

  • Patent number: 8937742
    Abstract: A multifunctional peripheral includes an image reading unit, an image memory, a facsimile communication unit, a modification instruction reception unit, and a data modification unit. The image reading unit acquires data to be transmitted by facsimile. The image memory stores the acquired data. The facsimile communication unit performs facsimile transmission of the data in the image memory to a counterpart. The modification instruction reception unit accepts a modification instruction to modify the data of already transmitted and untransmitted pages, while the facsimile transmission to the counterpart is being performed. The data modification unit modifies the data of the page designated as object of the modification while the facsimile transmission is being performed.
