Embodiment Construction

[0013] The present invention relates to apparatus and methods for producing electrophotographic printed images on media. For clarity, the four edges of the media may be referred to herein as the leading edge, the trailing edge, and the two side edges with reference to the direction of travel through the printing press. The printed output is referred to by the term "printed area", which is defined by the length and width of the final printed product. A method of forming an electrophotographic borderless print includes: inserting media into a printer; providing print data to the printer; determining a media type; and determining whether borderless printing is possible based on the determined media type. While borderless printing would normally result in leading edge image defects, the printer preheats the leading edge of the media before it enters the fusing area of ​​the printer to achieve defect-free borderless printing.

[0014] In general, electrophotographic printing can o...

Abstract

A method and apparatus for determining whether borderless printing can be done based on media type and desired gloss level is provided. Also provided is a method, printer, and system whereby a defect-free borderless print can be achieved regardless of media type and gloss level of the finished print, wherein the method includes pre-heating of the leading edge of the media before it enters a fuser area of the printer.

Description

technical field [0001] The present invention relates to a method of determining whether borderless printing is possible on a given media type and printing borderless media. Background technique [0002] Printing methods have been developed to allow monochrome and full-color printing on many media, including inkjet printing, laser printing, and electrophotographic printing with toners. With the development of printed colors, especially photo-realistic colors, and improvements in the sharpness / sharpness of print quality, more photographic images are being printed by these techniques. In particular, electrophotographic printing is popular for printing text and images. This is still a very cost effective printing method. Additionally, electrophotographic printers exist that are capable of handling media of many different sizes, finishes and compositions. This enables the printing of text documents of various sizes, mixed text and images, and images in various formats. For ex...
