							Print/stop test
Use this diagnostic test to isolate the cause of problems such as image formation defects and jams
within the engine. The test can be programmed to stop from 0 to 60,000 ms.
Perform the print/stop test in the DIAGNOSTICS menu 1.Press the  Menu button 
.
2. Press the down arrow 
 button or the up arrow  button to navigate to the  DIAGNOSTICS menu.
3. Press the  OK button to select the menu.
4. Press the down arrow 
 button or the up arrow  button to navigate to the  PRINT/STOP TEST
sub menu.
5. Press the  OK button to select the sub menu.
6. Press the down arrow 
 button or the up arrow  button to set a stop time.
NOTE: Range is 0 - 60,000 milliseconds. The default is 0.
Table 3-5  Print/stop settings
DurationDescription
0 msecsThe leading edge of the paper stops about 10 mm (0.36 in) beyond the silver paper guide of the
registration assembly.
100 msecsThe leading edge of the paper stops about 24 mm (0.94 in) beyond the silver paper guide of the
registration assembly.
500 msecsThe leading edge of the paper stops prior to the paper entering the “nip” of the fuser assembly; the
nip is the gap between the pressure roller and the hot fusing roller.
1000 msecsThe leading edge of the paper stops about 55 mm (2.17 in) beyond the fuser assembly output rollers.
1200 msecsSimplex print operation: The leading edge of the paper stops 100 mm (3.94 in) past the face-down
delivery stacker rollers.
1,500 msecsSimplex print operation: The leading edge of the paper stops 5 mm (0.20 in) beyond the output-bin-
full sensor flags.
2,500 msecsDuplex print operation: The leading edge of the paper has passed through the fuser assembly and
into the output stacker rollers. The paper has now reversed direction and stopped 90 mm (3.55 in)
before the leading edge reaches the output-bin-full sensor flags.
3,000 msecs Duplex print operation: The leading edge of the paper has passed through the fuser assembly and
into the output stacker rollers. The paper has now reversed direction and entered the duplex
accessory. The leading edge of the paper stops about 15 mm (0.59 in) after encountering the duplex
media-feed sensor (PS502).
7.Press the  OK button to start the test.
8. Send a print job to the product. The product will stop printing at the selected time.

							Component tests
Half self-testPerform a half self-test to determine which image-formation process might be malfunctioning.
NOTE:It might be easier to perform the print/stop test to stop the product during the printing process.
See 
Print/stop test on page 157.
1. Print a configuration page from the control panel.
2. Open the cartridge door after the paper advances half-way through the product, which is about 3
to 5 seconds after the main motor begins to rotate. The leading edge of the paper should have
advanced past the print cartridge.
3. Remove the print cartridge.
4. Open the print cartridge drum shield to view the drum surface.
If a dark and distinct toner image is present on the drum surface, assume that the cleaning,
conditioning, writing, and developing functions of the electrophotographic process are functioning
correctly. Troubleshoot the failure as a transfer or fusing problem. If no image is present on the
drum, perform the drum rotation test check. See 
Drum rotation test check on page 158.
Drum rotation test check
NOTE: This test is especially important if refilled print cartridges are in use.
The photosensitive drum, which is located in the print cartridge, must rotate in order for the print process
to work. The photosensitive drum receives its drive from the main gear assembly. Use this procedure
to determine whether the drum is rotating.
1.Open the cartridge door.
2. Remove the print cartridge.
3. Mark the cartridge drive gear with a felt-tipped marker. Note the position of the mark.
4. Install the print cartridge, and then close the cartridge door. The start-up sequence should rotate
the drum enough to move the mark on the gear.
5. Open the product and inspect the mark on the cartridge drive gear.
Verify that the mark moved. If there was no movement, inspect the main gear assembly to make
sure that it connects with the print-cartridge gears. If the drive gears function but the drum does
not move, replace the print cartridge.
Diagnostics menu components test Use this diagnostic test to isolate and test individual product components.
