Determining high toner usage

摘要

According to a method herein, a number of pixels marked and times of printing are automatically determined for a plurality of images. A time-based moving window of pixel counts for a subset of the plurality of images being contiguously processed in a current time window is automatically calculated, based on the number of pixels marked and the times of printing of the subset of the plurality of images processed in the current time window. Marking material usage to print the plurality of images for the current time window is automatically determined, based on the time-based moving window of pixel counts of the current time window. The method automatically determines if the marking material usage for the current time window exceeds a threshold. A notification is automatically output if the marking material usage for the current time window exceeds the threshold.

1. A method comprising:
automatically forming a queue of image descriptors, using a computerized device, each image descriptor in said queue comprising a number of pixels marked on an image and a time of marking said image using an image marking device, said queue comprising said image descriptors recorded over a selected time window; responsive to a new image descriptor being added to said queue, said new image descriptor having a new time mark:
automatically determining a queue window based on said new time mark and said selected time window, using said computerized device,removing from said queue any image descriptors falling outside said queue window, andautomatically calculating a total number of pixels marked on images for all image descriptors in said queue window, using said computerized device; and automatically determining toner usage in said queue window based on said total number of pixels, using said computerized device.
