Abstract: Systems and methods are described that facilitate mitigating processor overload and reducing memory waste during image compression. Clients requesting memory allocation are assigned a direct memory access (DMA) channel to which DMA memory blocks are allocated for use during image compression. As each DMA block is used by its channel, the DMA block generates an interrupt message that is counted by a DMA counter and may be optionally processed by the CPU. If the number of interrupts being processed exceeds a first threshold, then memory block size is increased to reduce processor load. If the number of interrupts is below a second, lower threshold, then block size is decreased to reduce and amount of unused but allocated memory in the final block allocated to the channel a compressed image file.

Abstract: A compression and storage device comprises: a compressor configured to compress data; a central processing unit (CPU) configured to control storage of the compressed data and to perform at least one additional task; an electronic memory organized as storage blocks each having a storage block size; a direct memory access (DMA) engine configured to operate autonomously from the CPU to transfer a current transfer block of compressed data into one or more storage blocks of the electronic memory; and a transfer block size estimator configured to select a transfer block size for the current transfer block based on previous DMA transfers of compressed data, the selected transfer block size being generally different from the storage block size.

Abstract: The presently disclosed embodiments are directed to systems and methods for transmitting a secure electronic fax or scan transmission report for a fax or scan job from a fax capable printer or a multifunctional device respectively. When the electronic confirmation (EConfirmation) option is selected, the machine sends an email comprising a status of the fax or scan job to the sender and a hyperlink. The sender then selects or “clicks” on the hyperlink, which connects to the machine Web (UI) Services. Web services automatically retrieves the job information and correctly displays all previously entered selections. The sender then simply verifies the information, makes any necessary changes and selects or “clicks” a button on the Web services to retransmit the fax or scan documents. In another embodiment, the sender is given an option to reformat a scan job by compressing or changing job parameters of the scan job.

Abstract: The presently disclosed embodiments are directed to systems and method for transmitting a secure electronic fax transmission report for a fax job from a fax capable printer to a user or recipient and sending commands for resubmitting or deleting the fax job from the user to the fax capable printer. One embodiment is a method for electronically transmitting a fax transmission report for a fax job from a fax capable printer. An email address is received for the user or the recipient. A recipient fax number is received. A document is scanned and an electronic representation of the document is transmitted to the recipient fax number as a fax job. The fax transmission report is generated. The fax transmission report includes the status of the fax job. An email including the fax transmission report is transmitted to the email address of the user or the recipient.
