Abstract

This idea proposes a way to print banner sheets more productively in a phase change Ink printer, saving time and resources. The idea proposes that banner sheets could be printed in draft mode, at a lower resolution, or by accepting an overall lower image quality than for the actual print job by not using the failed jet substitution feature.

Print banner sheets with jet substitution off

This idea proposes a way to print banner sheets more productively in a phase change Ink printer, saving time and resources.  The idea proposes that banner sheets could be printed in draft mode, at a lower resolution, or by accepting an overall lower image quality than for the actual print job by not using the failed jet substitution feature.

Some phase change Ink printers have the ability to detect and hide a missing or failed ink jet. These printers use an Image on Drum Sensor to detect missing jets and fill in these missing jets (if needed) with the use of extra imaging drum revolutions. This slows down the productivity of the printer, but maintains print quality.  That tradeoff may make sense for the print job but might be considered wasteful on banner sheets.  This idea proposes to use draft mode printing, lower resolution printing, or turn off jet substitution mode for banner sheets in order to increase productivity.  Banner sheets are printed for a number of reasons (e.g. job separators and startup pages) and have reduced print quality requirements (as they are not part of a customer's output). Therefore, banner sheets present an opportunity to use the ability of the printer in order to trade off the print quality for print speed. This would have the effect of always producing banner sheets with the minimum delay to the requested print job.
