Abstract
Abstract A continuous-paper electrophotographic printer prevents the printed paper from being either scorched or needlessly paid out during periods when printing is halted to enable receipt of a next batch of printing data. This is accomplished by reducing the paper feeding rate between printing periods. Thereby, the printer can rapidly proceed to a next printing operation when inputting of the next data to be printed is completed within a time period that is provided for checking whether the next set of print data is ready.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A continuous-paper electrophotographic printer, comprising: printing means which is activatable for imprinting selected information on continuous paper; continuous-paper feeding means for supplying and transporting continuous paper to the printing means; means for supplying to the printing means sets of data to be imprinted; control means for interposing a monitoring time period for checking the readiness of each successive set of data to be imprinted; and said continuous paper feeding means including means for feeding the paper to the printing means at a first comparatively high speed during activation of the printing means and at a second lower speed during the monitoring time period.
Claim 2
Dependent Claim
103 words
A continuous-paper electrophotographic printer, comprising: printing means which is activatable for imprinting selected information on continuous paper; continuous-paper feeding means for supplying and transporting continuous paper to the printing means; means for supplying to the printing means sets of data to be imprinted; control means for interposing a monitoring time period for checking the readiness of each successive set of data to be imprinted; and said continuous paper feeding means including means for feeding the paper to the printing means at a first comparatively high speed during activation of the printing means and at a second lower speed during the monitoring time period.
Claim 3
Dependent Claim
14 words
The printer of claim 1, wherein said monitoring time period is about 3 seconds.
Claim 4
Dependent Claim
13 words
The printer of claim 1, wherein the printing means comprises a light-sensitive drum.
Claim 5
Dependent Claim
14 words
The printer of claim 3, wherein the printing means further comprises an LED head.
Claim 6
Dependent Claim
16 words
The printer of the claim 4, wherein the printing means further comprises an electrophotographic transfer element.
Claim 7
Dependent Claim
39 words
The printer of claim 1, wherein the continuous paper feeding means comprises a transport drive roller and a reel for holding a supply of continuous paper, the transport drive roller being disposed between the reel and the printing means.
Claim 8
Dependent Claim
25 words
The printer of claim 6, further comprising means for cutting the paper, the paper cutting means being disposed between the reel and the printing means.
Claim 9
Dependent Claim
41 words
The printer of claim 1, wherein the control means comprises a microcomputer and speed control means, responsive to the microcomputer, the control means being effective for controlling the transport drive roller and thereby the speed of feeding of the continuous paper.
Claim 10
Independent Claim
123 words
A method for imprinting information on continuous-paper in a electrophotographic printer, the method comprising the steps of: providing printing means which is activatable for imprinting selected information on continuous paper; providing a continuous-paper feeding means and supplying and transporting therewith continuous paper to the printing means; supplying to the printing means sets of data to be imprinted; interposing a monitoring time period between the imprinting of the continuous paper with successive ones of sets of data to be imprinted and checking the readiness of each successive set of data to be imprinted; and feeding the paper to the printing means at a first comparatively high speed during activation of the printing means and at a second lower speed during the monitoring time period.
Claim 11
Independent Claim
123 words
A method for imprinting information on continuous-paper in a electrophotographic printer, the method comprising the steps of: providing printing means which is activatable for imprinting selected information on continuous paper; providing a continuous-paper feeding means and supplying and transporting therewith continuous paper to the printing means; supplying to the printing means sets of data to be imprinted; interposing a monitoring time period between the imprinting of the continuous paper with successive ones of sets of data to be imprinted and checking the readiness of each successive set of data to be imprinted; and feeding the paper to the printing means at a first comparatively high speed during activation of the printing means and at a second lower speed during the monitoring time period.
