This test looks at the paper path sensors to identify if anything would prevent
a page from printing. The Control Panel will display messages indicating if
anything unexpected is found for: R0 = upper paper path; R1 = tray 1; R2 =
tray 2; R3 = tray 3; and R4 = tray 4. The display is a string of 0's and 1's (one
digit for each sensor state) and is listed below from most significant bit to least
significant bit.
1 = an item that needs to be corrected.
0 = normal
