Error Log
Viewing the Error Log
The error log is helpful to the servicer by providing a history of
printer errors. The error log contains the 12 most recent errors that
have occurred on the printer. The most recent error displays in
position 1 and the oldest error displays in position 12 (if 12 errors
have occurred). If an error occurs after the log is full, the oldest error
is discarded. Identical errors in consecutive positions in the log are
entered. All 2xx and 9xx error messages are stored in the error log.
To view the Error Log:
1. Select Display Log from the Error Log menu.
– The Error log displays on 3 screens as only 4 entries display
at a time.

passed and finished successfully. Initially 000000 displays with the
maximum pass count being 999,999.
F:##### represents the of time the memory test has failed and
finished with errors. Initially 00000 displays with the maximum fail
count being 99,999.
Once the maximum pass count or fail count is reached, the test is
stopped, the power indicator is turned on solid, and the final results
display. If the test fails, the message DRAM Error, displays for
approximately 3 seconds and the failure count increases by 1.

Input Tray Tests
Input Tray Feed Test
This test lets the servicer observe the paper path as media is
feeding through the printer. A blank sheet of paper feeds through the
printer as the laser turns off during this test. The only way to observe
the paper path is to open the lower front door that is used to access
the envelope or multipurpose feeder. The paper is placed in the
output bin.
To run the Input Tray Feed Test:
1. Select Input Tray Feed Test from the menu.
2. Select the input source from the sources displayed on the
Feeds Test menu. All installed sources are listed.
3. Select either Single (feeds one sheet of media from the selected
source) or Continuous (continues feeding media from the
selected source until Return/Stop is pressed).
4. Press Return/Stop to exit test.
Input Tray Sensor Test
This test is used to determine if the input tray sensors are working
correctly.
To run the Input Tray Sensor Test:
1. Select the Sensor Test from the Input Tray Test menu.
– Input Tray/Empty=OP/Pass=OP message displays.
– EM = Input Tray Empty Sensor
– LO = Input Tray Paper Low Sensor
– P = Input Tray Pass Thru Sensor
2. Once this message displays, the servicer can manually actuate
each sensor. The tray empty sensor can be actuated by hand,
however a sheet of paper can be used to cover the pass
through sensor. When the sensor is closed, CL displays, when
the sensor is open, OP displays.
3. Press Return/Stop to exit the test.

The multipurpose tray and the envelope feeder do not have a paper
low sensor. The multipurpose tray does not have a pass thru sensor.
OutputBinTest-StandardBin
This test is used to verify if the standard bin sensor is working
correctly.
To run the Standard Bin Sensor Test:
1. Select Output Bin Tests from the Diagnostic Menu.
2. Select Output Bin Tests - Sensor Tests.
3. Select Sensor Tests - Standard Bin.
– “Standard Bin/Full=CL” message displays.
Manually actuate the bin sensor by moving the flag in and out of the
sensor. The display indicates OP (open) when the flag is out of the
sensor and CL (closed) when the flag is in the sensor.
4. Press Return/Stop to exit the test.
OutputBinFeedTest
Note:If the “Configure Bins” printer setting is link rather than
mailbox, the printer selects its own internal bin linking regardless of
which output bin is selected for the feed test
This test is to verify that media can be fed to a specific output bin. No
information is printed on the media because the printhead is not
turned on during this test.
To run the Output Bin Feed Test:
1. Select Feed Test from the Output Bin Test menu.
2. Select the output bin you want the paper to exit into. All output
bins installed on the printer are shown on the feed test menu.
3. Select either Single (one sheet of media feeds to the selected
output bin) or Continuous (media continues feeding to the
selected output bin) until Return/Stop is pressed.
4. Press Return/Stop to exit the test.

Output Bin Sensor Test
This test is used to verify if the output bin sensors are working
correctly.
To run the Output Bin Sensor Test:
1. Select Sensor Test from the Output Bin Test menu.
– Output Bin/Full=OP/Input=OP message displays.
– Full = Output Bins Full Sensor
– Pass = Output Bins Pass Thru Sensor
2. Once the message displays, the servicer can manually actuate
each of the output bin sensors. The bin full sensor can be
actuated by hand, however a sheet of paper can be used to
cover the bins pass thru sensor. When the sensor is closed CL
displays, and when the sensor is open OP displays.
3. Press Return/Stop to exit the test.
Output Bin X Sensor Test
Note:Some output expanders have a single output bin sensor
installed while others have a dual sensor assembly. Both versions
have a single pass thru sensor. This test is used to verify if the
Output Bin X sensors are working correctly.
To run the Output Bin X Sensor tests:
1. Select Output Bin tests from the menu.
2. Select Output Bin tests - Sensor Tests.
3. Select Sensor Tests - Output Bin X.

Output Expander with Dual Sensor:
The following is displayed:
Output Bin X
P=OP F=OP NF=CL
P = Pass Thru Sensor
F = BIN FULL Sensor (lower part of dual sensor)
NF = Near Full Sensor (upper part of dual sensor)
Once the message displays, the servicer can manually actuate each
of the output bin sensors. The bin full sensor can also be actuated
by hand. Use a sheet of paper to cover the bins pass thru sensor.
When the sensor is closed CL displays, and when the sensor is
open OP displays.
4. Press Return/Stop to exit the test.
Base Sensor Test
This test is used to determine if the sensors located inside the
printer are working correctly.
The following sensors can be checked:

Front Door Sensor (Upper Front Cover)
To run the Base Sensor Test:
1. Select the Base Sensor Test.
– The operator panel displays OP for open and CL for closed.
2. Manually toggle the sensors by hand to verify that each sensor
switches from open to closed.
