EPSON Color Copy Station 8200

5.1.2 Size Collection (Adjusting the Precision)

This function adjusts the mechanical precision (the individual
differences) between the scanner and the printer, and minimizes the
measurement gap between the original and the copy result. This
function outputs the pulse (the digital rectangle pattern) generated
inside of the copy server to the printer, reads these signals with the
scanner, calculates the adjustment scale, and reflect the result to the
scanning resolution for printing out.
Note that the adjusted value is valid only for printing out. Also, note this
function is not open to the end user, presupposing the servicemen use
this function for maintenance.
SHIFTING MOOD METHOD
With "0", ".", and "C" on the control panel all pressed, turn on the power
supply of the copy server to shift to the maintenance mood main view.
