Paper Path Status (Test ID #3) - This test looks at the paper path sensor to identify if anything
would prevent a prage from printing. The front panel will display messages indicating if anything
unexpected is found. The diagnostics history reports a single result, R0, which is a string of 0’s
and 1’s, one digit for each sensor state (24 total).
1 = the sensor state was normal.
0 = the presence of paper, an open door or missing tray (if the printer has no lower trays, those
sensors report 0’s).
These are the typical results for a printer
with no lower trays.
