A system for estimating pixel coverage in a digitized image including a controller for sampling pixels in a byte stream according to a varying spaced sampling mode so as to avoid image pattern errors. A processor for sums the sampled pixels, so that a total pixel on count in the digitized image may be estimated. A plurality of pixels may be included in bytes in the data stream; a look-up table, random number generator or other device may be used to select the addresses of the bytes to be sampled in the byte stream. The system may include an ink metering controller for providing ink to a printer or a printer service status indicator for providing various forms of printer consumable and component service data.

An automatic xerographic set up and monitoring process for a multi-mode electrostatographic machine in which a corona charge intercept value is obtained and used to optimally set corona charging levels for different modes, optimum flash exposure levels obtained, ID lamp intensity correlated with flash exposure levels, and xerographic process parameters set for each different mode.
