A reprographic system is provided and includes a digital multi-function reprographic machine for reproducing copies of original images and a programmed personal computer (PC) subsystem. The programmed personal computer (PC) subsystem is connected to the multi-function reprographic machine for processing and controlling original images to be reproduced by the multi-function reprographic machine, and includes a work station monitor having a user screen, a machine-client dialog box, and a drop-down reduction/enlargement (R/E) window. The drop-down reduction/enlargement (R/E) window includes a drop-down arrow, a value display area, selectable preset major R/E values, and increasing-value and decreasing-value fine tuning devices for efficiently and quickly varying a selected selectable preset major R/E value for controlling an original image processed by the PC subsystem and being reproduced by the multi-function reprographic machine.
