Paper Path Status (Continued)
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
