Abstract

Abstract A data printer has the ability to print machine-readable information and, further instream, the ability to read and analyze such information. Results of that analysis are reporated back to a job control processor which, according to the analysis, monitors print quality, instructs the print engines to adjust print contrast, causes unacceptable pages to be invalidated, rejected and reprinted, and advises the operator regarding corrective actions to improve print quality or to reconcile print jobs.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 117 words
In combination in a data printer having paper feeding means for feeding paper along a paper path from an outstream paper supply to an instream paper stacker and at least one print engine located on the paper path and responsive to externally-supplied digital signals for imprinting on the paper alphanumeric information specified by the digital signals: a job control processor comprising digital computer means for a controlling elements of the printer; means in the print engines responsive to the digital signals or the job control processor for imprinting machine-readable characters on the paper; and means instream from the print engines for reading machine-readable characters and for sending digital representations of the characters to the job control processor.
Claim 2
Dependent Claim 117 words
In combination in a data printer having paper feeding means for feeding paper along a paper path from an outstream paper supply to an instream paper stacker and at least one print engine located on the paper path and responsive to externally-supplied digital signals for imprinting on the paper alphanumeric information specified by the digital signals: a job control processor comprising digital computer means for a controlling elements of the printer; means in the print engines responsive to the digital signals or the job control processor for imprinting machine-readable characters on the paper; and means instream from the print engines for reading machine-readable characters and for sending digital representations of the characters to the job control processor.
Claim 3
Dependent Claim 30 words
The combination recited in claim 1, wherein further: the machine-readable character reading means performs signal strength and quality analysis of the machine-readable characters and generates contrast signals from that analysis.
Claim 4
Dependent Claim 37 words
The combination recited in claim 2, wherein further the contrast signals are forwarded to the print engines and the print engines adjust contrast of imprinted characters responsive to the contrast signals, whereby print contrast is dynamically controlled.
Claim 5
Dependent Claim 26 words
The combination recited in claim 2, wherein further the job control processor determines from the strength and quality analysis whether each page is of acceptable quality.
Claim 6
Dependent Claim 32 words
The combination recited in claim 4, further comprising means instream from the machine-readable character reading means and responsive to the job control processor for selectively marking pages of unacceptable quality as invalid.
Claim 7
Dependent Claim 23 words
The combination recited in claim 5, further characterized in that the job control processor signals the print engines to reprint the invalidated pages.
Claim 8
Dependent Claim 51 words
The combination recited in claim 6, further characterized in that, responsive to the job control processor, all pages in the print engines or instream from the print engines but outstream from the invalidation means at the time of invalidation of a page are invalidated and reprinted regardless of the quality analysis.
Claim 9
Dependent Claim 58 words
The combination recited in claim 7, further characterized in that the stacker has a plurality of bins and means for selectively routing pages to any of the bins, and in that all valid pages are selectively routed, responsive to the job control processor, to first certain bins and all invalidated pages are selectively routed to second certain bins.
Claim 10
Dependent Claim 47 words
The combination recited in claim 6, further characterized in that the job control processor furnishes a report directing an operator regarding the positions of invalidated pages in the stacker, the positions of reprinted replacements for such invalidated pages, and instructions for replacing the former with the latter.
Claim 11
Dependent Claim 77 words
The combination recited in claim 2, further characterized in that: results of signal strength and quality analysis are periodically forwarded to the job control processor; the job control processor tabulates the signal strength and quality analysis results and maintains queues of data for informing an operator of printer status and recommending a corrective actions to an operator; and the job control processor provides reports of printer status and recommended corrective actions to the operator upon his request.
Claim 12
Dependent Claim 30 words
The combination recited in claims 5, 6, or 7 wherein further: the job control processor accounts for all paper used and reports those accounts to an operator upon his request.
Claim 13
Dependent Claim 52 words
The combination recited in claim 1 wherein further: the job control processor further comprises a removable-media data storage device; and the job control processor retrieves certain information from the data storage device and forwards it to the print engines for imprinting on the paper along with information specified by the digital signals.
Claim 14
Dependent Claim 35 words
The combination recited in claim 12 wherein further: the job control processor, responsive to certain of the externally-supplied digital signals, directs an operator to load media onto or remove media from the data storage device.
Claim 15
Dependent Claim 83 words
The combination recited in claim 1, wherein further: the job control processor compares the characters read by the machine-readable-character reading means with those specified by the externally-supplied digital signals; a means outstream of the reading means, responsive to the job control processor, marks certain pages as invalid; and for any pages on which characters read by the reading means do not correspond to those specified by the digital signals, the job control processor signals the invalidation means to mark such pages as invalid.
Claim 16
Dependent Claim 22 words
The combination recited in claim 14, wherein further: the job control processor directs the print engines to reprint pages marked as invalid.
