Designjet 800 "Pattern not found"

[Shadow Wizard]

This has got to be a simple problem. I am trying to do an advanced calibration. I have printed the pattern. I load it into the printer, rotated 90 degrees with the pattern of dots being the first thing that would come out of the printer. After the paper is loaded with the proper method (Selecting load paper -> sheet -> High gloss photo) I select "Measure pattern" the machine advances the paper, but does not advance it far enough. It attempts to locate and read the pattern, but since the paper hasn't be fed far enough there is no pattern for it to read. Thus it tells me "Pattern not found" What am I doing wrong?
