Abstract:
1. A marking machine comprising a printing system, said printing system comprising a predetermined printing rate and an operably integrated sheets feeding system for unprinted media sheets, said operably integrated sheets feeding system feeding said unprinted media sheets to said printing system at said pre-determined printing rate of said printing system from at least two separate sheet feeders feeding from at least two separate stacks of said unprinted media sheets, said at least two separate sheet feeders are controlled by a system controller programmed with a sheet feeding algorithm to alternately feed said unprinted media sheets to said printing system from said at least two separate sheet feeders into at least two separate fed sheets streams at a sheet feeding rate of approximately one-half or less of said printing system printing rate from each of said at least two separate sheet feeders, wherein a sheet merging position is provided for merging said at least two separate fed sheet streams, and wherein said system controller sheet feeding algorithm is enabled to send sheet feeding commands to said at least two sheet feeders at programmed times such that said at least two separate sheet feeders feed sheets into said respective said at least two fed sheet streams at times which allow said at least two fed sheet streams to interleave into a single fed sheet stream (
