The test takes approximately 15 seconds to run.

Components exercised by the paper path test include the fusing motor 
(M1), paper path motor (M2), and associated gears and assemblies. 
The paper pick roller for Tray 2 can be activated by manually activating 
the paper pick solenoid (SL2). This test will not pick paper and move it 
through the paper path. To test this function, run a configuration page. 
For multiple pages, select 

CONTINUOUS CONFIGURATION PAGE

 in the 

control panel.

The paper path test allows the service technician to verify the operation 
of components within the paper path. When the test is initiated, both M1 
and M2 are activated. You will see the ITB lift cams rotate once and the 
ITB drive gear turn briefly. The remaining portion of the test allows both 
M1and M2 to run, thus exercising the associated gears and rollers.
