Claim 5

In an electronic color printer in which an array of images from respective frames of a filmstrip or the like is provided on print receiver sheets from information signals representing image information, said electronic printer including a photoconductive recording member, marking particle development stations for developing electrostatics latent images on such photoconductive recording member, a transfer device for transferring marking particle developed images from such photoconductive recording member to a receiver sheet, and a fusing device for fusing transferred images to such receiver sheet, a control device for producing prints from the array of images, said control device comprising: a) means for pre-scanning, at low resolution, an array of images contained on respective frames of a filmstrip or the like, and producing an information data stream respective thereof; b) means, responsive to said information data stream for storing information data, obtained during low resolution pre-scanning, of at least the number of printable images; c) a movable photoconductive recording image member having an image receiving portion and a non-image receiving portion; d) means for forming images on said movable photoconductive recording image member; and e) means for controlling the speed of said movable photoconductive recording image member in response to said pre-scanning information to ensure that said image receiving portion of said movable photoconductive recording image member is positioned to receive images from said image-forming means.

Claim 6

In an electronic color printer in which an array of images from respective frames of a filmstrip or the like is provided on print receiver sheets from information signals representing image information, said electronic printer including a photoconductive recording member, marking particle development stations for developing electrostatics latent images on such photoconductive recording member, a transfer device for transferring marking particle developed images from such photoconductive recording member to a receiver sheet, and a fusing device for fusing transferred images to such receiver sheet, a control device for producing prints from the array of images, said control device comprising: a) means for pre-scanning, at low resolution, an array of images contained on respective frames of a filmstrip or the like, and producing an information data stream respective thereof; b) means, responsive to said information data stream for storing information data, obtained during low resolution pre-scanning, of at least the number of printable images; c) a movable photoconductive recording image member having an image receiving portion and a non-image receiving portion; d) means for forming images on said movable photoconductive recording image member; and e) means for controlling the speed of said movable photoconductive recording image member in response to said pre-scanning information to ensure that said image receiving portion of said movable photoconductive recording image member is positioned to receive images from said image-forming means.

Claim 7

The electronic color printer as set forth in claim 4 wherein said means for controlling the speed of said movable photoconductive recording image member includes means for selectively stopping and starting said movable photoconductive recording image member that is moved at a constant speed during image formation.

Claim 8

The electronic color printer as set forth in claim 5 wherein said movable image member takes the form of a cylindrical drum.

Claim 9

The electronic color printer a set forth in claim 5 wherein said movable image member takes the form of an endless belt having a photoconductive surface.

Claim 10

The electronic color printer a set forth in claim 5 wherein said stopping of said movable photoconductive recording image member occurs only at the beginning of a batch of said printable images.

Claim 11

An electronic printing apparatus for printing an array of images contained on frames of film on a per-batch basis comprising: a) a movable image member having an image receiving portion and a non-image receiving portion; b) means for pre-scanning, an array of images contained on respective frames of film and providing a first signal; c) means for determining the position of said movable image member and generating a second signal in response thereto; d) means for forming images on said movable image member; and e) control means responsive to said first and second signals to control the position of said movable image member by selectively stopping and starting said image receiving portion so that it is positioned to receive an image from said image-formed means.

Claim 12

An electronic printing apparatus for printing an array of images contained on frames of film on a per-batch basis comprising: a) a movable image member having an image receiving portion and a non-image receiving portion; b) means for pre-scanning, an array of images contained on respective frames of film and providing a first signal; c) means for determining the position of said movable image member and generating a second signal in response thereto; d) means for forming images on said movable image member; and e) control means responsive to said first and second signals to control the position of said movable image member by selectively stopping and starting said image receiving portion so that it is positioned to receive an image from said image-formed means.

Claim 15

The method as set forth in claim 10 wherein the controlling of the position of the image member is accomplished by stopping said image member that moves at a constant speed.

Claim 16

The method as set forth in claim 11 wherein said stopping of said image member occurs only when starting to print a batch of color prints.

Claim 17

The method as set forth in claim 11 wherein said pre-scanning information is used to stop the image member to ensure that said image-receiving portion is positioned to receive images from said image-forming means.

Claim 20

The method as set forth in claim 14 wherein the controlling of the position of the image member is accomplished by stopping an image member that moves at a constant speed during image formation.

Claim 21

The method as set forth in claim 15 wherein said pre-scanning information is used to stop the image member to ensure that said image-receiving portion is positioned to receive images from said image-forming means for the next batch of prints.

Claim 22

The method of as set forth in claim 15 wherein the length of time the image member is stopped depends on the position of the image member when the pre-scanning is complete and when printing can begin.
