Check Menu Value Keys and Descriptions

Refer to the tables associated with each test for their normal operating ranges, the 'R'
values, and the suggested troubleshooting steps if the test results exceed the given
range(s). In cases where insufficient baseline data is available, the results have been
left blank. All results from tests that move paper through the printer were collected
using 24 lb bond paper.
Note: Collecting 2 or 3 samples of the test data is recommended before deciding
on a course of action. Many of the tests rely on mechanical positions and slight
changes can effect the results. Ensure that the printer is not out of paper, ink or
maintenance kit life. The diagnostics routines are not designed to address all of these
conditions consistently.

Paper Path Status - This test looks at the paper path sensors to identify if anything would
prevent a page from printing. The front 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
