An apparatus for digitally printing comprising: a plurality of electrophotographic printing engines each in one of two or more of different print assemblies that are capable of printing on a receiver to form one or more final prints wherein the print engines are alignable in an x, y and z direction relative to a receiver path cross track reference for sequentially printing on a receiver wherein the receiver path cross track reference is based on measurements in the cross track direction (z direction) relative to the receiver path cross track reference; a measurement device to measure a location of a receiver in the receiver path at a final one of the sequence of print assemblies; and an alignment device to align the two or more printing engines in the cross track direction (z direction) relative to the receiver path cross track reference based on the measurement. view more

A system with operator enabled maintenance comprising:</claim-text> at least one computational element within said system; a plurality of operator replaceable component (ORC) devices within said system, each of said ORC devices having an expected span; a use mechanism coupled to each said computational element and said ORC devices, said use mechanism tracking use of at least one of said ORC devices using a predetermined parameter; a comparison mechanism that compares use of said ORC devices to said expected life span; and an operator alert mechanism responsive to said comparison mechanism to provide said operator alert when the result of said comparison satisfies a predetermined parameter representing at least one of said expected life spans where said expected life span for a single of said ORC devices is the shortest expected life span. view more

A method for providing operator maintenance on a system having a plurality of operator replaceable component devices, comprising:</claim-text> providing the expected life span of each of the operator replaceable component devices; determining a ning life span for the operator replaceable component device having the shortest expected life span; comparing said remaining life span with a predetermined threshold; responding to a result of the comparing step indicating that said predetermined threshold has been exceeded; and notifying the operator on a periodic basis that said predetermined threshold has been exceeded. view more

A system for pre-selecting ordered media in a printing system, comprising:</claim-text> (a) an input source to store at least one set of the ordered media; (b) a user interface having an input device to select the ordered media from a paper catalog, o pre-select a first part of the ordered media set to be used in a print job and a second unwanted part of the ordered media set to be discarded; (c) a first job output; (d) a second job output; and (e) a central processing unit configured to send the first part of the ordered media set directly to the first job output and the second part of the ordered media set directly to the second job output. view more
