Abstract
A system for analyzing pages has a circuit for generating page information, a circuit for determining if the page information represents a blank page, a blank page counter that is incremented if a blank page is detected, a comparator for comparing the blank page counter to a blank page threshold memory, and an error indicating circuit that indicates an error signal if the blank page counter exceeds the blank page threshold and a detect signal is active. The page analysis system detects blank pages within a job and distinguishes between initial blank pages caused by incorrectly oriented original pages within a machine, and intentionally blank pages within the middle of a job.
Claims21
A method for analyzing pages, comprising the steps of:
- determining a beginning of a job;
- obtaining page information included in the job;
- determining if a page represented by the page information is a blank page;
- determining if the job is past the beginning when the page is determined not to be a blank page;
- incrementing a blank page counter when the page is determined to be a blank page;
- comparing the blank page counter to a blank page threshold;
- and
- indicating an error has occurred when the comparing step determines that the blank page counter has exceeded the blank page threshold and the job is not past the beginning.
A system for analyzing pages, comprising:
- means for determining a beginning of a job;
- means for obtaining page information included in the job;
- means for determining if a page represented by the page information is a blank page or an information page;
- means for generating an override signal if an information page is detected;
- means for incrementing a blank page counter if the page is determined to be a blank page;
- means for comparing the blank page counter to a blank page threshold;
- and
- means for indicating an error has occurred when a blank page is detected and no override signal has been generated.
A system for analyzing pages, comprising:
- means for determining a beginning of a job;
- means for obtaining page information included in a job;
- means for determining if a page represented by the page information is a blank page;
- means for generating an override signal if an information page is detected;
- and
- means for indicating an error has occurred when a blank page is detected and no override signal has been generated.
A printing system, comprising:
- an information input which receives page information of a print job;
- means for determining if the page information includes a plurality of consecutive blank pages at a beginning of the print job;
- a printer which prints the page information;
- and
- a controller which stops the printer from printing the page information when the means for determining determines that the page information includes a plurality of consecutive blank pages at the beginning of the print job and operates without stopping the printer when the plurality of blank pages exist after the beginning of the print job.
A facsimile machine, comprising:
- a scanner which generates page information from a scanning job;
- means for determining if the page information includes a plurality of consecutive blank pages at a beginning of the scanning job;
- a transmitter which transmits the page information;
- and
- a controller which stops the transmitter from transmitting the page information when the means for determining determines that the page information includes a plurality of consecutive blank pages at the beginning of the scanning job and operates without stopping the transmitter when the plurality of blank pages exist after the beginning of the scanning job.
A computer program product having a computer readable medium having computer program logic recorded thereon for determining if page information of a job includes a plurality of consecutive blank pages at a beginning of the job, comprising:
- means for determining the beginning of the job;
- means for determining if a page represented by the page information is a blank page;
- means for determining the job is past the beginning when the page is determined not to be a blank page;
- means for incrementing a blank page counter if the page is determined to be a blank page;
- means for comparing the blank page counter to a blank page threshold;
- and
- means for determining a plurality of consecutive blank pages exist when means for comparing determines that the blank page counter has exceeded the blank page threshold and when the job is not past the beginning.
