Summary of the invention
A purpose of the present invention, be to provide one can in the time of the blank page printing face, send the method that information warning is notified the user automatically, it makes printer when printing, utilize additional scanning equipment, this page of scanning after printing, and the result that will scan is accessed in the internal memory, if the percentage that the use percentage of internal memory is set greater than the user, then be considered as the blank page, and the accumulative total of the blank page is promptly sent information warning automatically and is notified the user during greater than the number of pages set.
Another object of the present invention, be to provide a printer that is available for users to change at any time page empty ratio and blank page setting according to demands of individuals, because it is when the page number that blank page number is set greater than the user, can send information warning automatically and notify the user, whether continue to print with decision, therefore, can improve the service efficiency of this printer and avoid the waste of paper.
The invention relates to a kind of alarming method for power of printer prints blank page, comprise the following step: (1) is set on printer and is distinguished that several parameter values, this parameter value contain blank page number and page empty ratio; (2) mimeograph documents are desired in scanning, scan this page after printing, and the result is accessed in the mnemon; (3) differentiate blank page number, the page empty the ratio whether blank page number be accessed to this mnemon, page empty ratio set greater than the user; (4) if during the blank page number that continuous blank page number is set greater than the user, promptly send the information of caution automatically and notify the user, whether continue to print with decision.
In order to make the auditor can further understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, accompanying drawing only for reference with the explanation usefulness, be not to be used for the present invention is limited.
The specific embodiment
The present invention is a kind of alarming method for power of printer prints blank page, and it utilizes additional scanning equipment, as Fig. 1, this page of scanning after printing, and the result that will scan is accessed in the internal memory, if the use percentage of internal memory then is considered as the blank page greater than the percentage that the user sets.Its computing formula is as follows:
The percentage that the use percentage=1-of internal memory (memory headroom that the complete page of the memory headroom that takies behind the actual scanning/one takies)>user sets
If the accumulative total of the blank page during greater than the number of pages set, is promptly sent information warning automatically and is notified the user (user can according to the demands of individuals setting of conversion percentage and blank number of pages at any time).
See also Fig. 1, structure chart for scanning device composition of the present invention, comprise a printer 11, an Output Tray 12 and one scan instrument (it contains an optical pick-up unit 13, a central processing unit 14, an internal memory 15 and a caution unit 16), wherein printer 11 is available for users to set the identified parameters value, and this parameter value contains blank page number (x) and page empty ratio (y); Internal memory 15 is in order to the page result of access through the scanning and printing file; Central processing unit 14 is in order to differentiate blank page number, the page percentage whether blank page number, page empty ratio set greater than the user.If the blank page of printing is greater than blank page number (x) continuously, then drive caution unit 16 automatically and send information warning, whether continue to print with decision; If the blank percentage that partly accounts for this page promptly is considered as being the blank page greater than this page empty ratio (y), and is as shown in the table.
The identified parameters title (x, y) | Definition |
Continuous blank page number (x) | If the blank page of printing promptly sends information warning greater than this parameter continuously |
Blank page ratio (y) | The blank percentage that partly accounts for this page promptly is considered as blank page greater than this parameter |
See also Fig. 2, for the present invention sets the flow chart of distinguishing several parameters on printer.If printer is at idle state 21, the user on printer, set the identified parameters value (x, y)? 22.
If on printer, set distinguish several parameter values, user then import the identified parameters value (x, y) 23, and store identified parameters 24, wait file to be printed 25, otherwise, use default identified parameters to be worth 26, wait file to be printed 25.
See also Fig. 3, flow chart for printer control, if printer is at idle state 31, receive new mimeograph documents 32, one page 34 is down printed in blank number of pages=0 33, removes memory content 35, scan this page and deposit the result in internal memory 36, differentiate internal memory and use percentage to set percentage (y) greater than the user? 37.
Do you if blank page number adds 1, differentiate the blank page number (x) that blank page number is set greater than the user? 39.
If not, be back to step 34; Otherwise, send information warning and temporarily stop to print 40, differentiate the user and cancel printing? 41.
If memory dump file 42 finishes to print 43.
Do you if the use percentage of internal memory is set percentage (y) less than the user, then differentiate file and whether have printed and finish? 44.
Do not finish if print, then be back to step 34; Otherwise, finish to print 43.
In sum, by design of the present invention, can make printer when printing, take a decision as to whether undesired printing according to user institute setting parameter, and can in the time of the blank page printing face, send information warning automatically and notify the user, whether continue to print with decision, and then improve the service efficiency of printer and avoid the waste of paper, therefore, the present invention meets the requirement of patent application fully, so file an application according to Patent Law.
The above, only for the present invention's one specific embodiment, feature of the present invention is not limited thereto, any people who is familiar with this technology in the field of the invention, can think easily and variation or modification all can be encompassed in the Patent right requirement scope of the present invention.
