Duplex Tests
Quick Test (duplex)
This test prints a duplex version of the Quick Test that can be used to verify the correct placement of the top 
margin on the back side of a duplex page.
Note:  Before you set the duplex top margin, be sure to set the registration. See “Registration” on page 3-4.
The paper you choose to print the page on should be either Letter or A4.
To run the Quick Test (duplex):
1.Select DUPLEX TESTS from Diag Menu, and press Select ().
2.Select Quick Test, and press Select ().
3.Select Single or Continuous, and press Select (). 
•The single Duplex Quick test prints the Quick Test on front and back.
•The printer attempts to print the Quick Test Page from the default paper source. 
•Check the Quick Test Page for the correct offset between the placement of the first scan line on the 
front and back side of the duplexed sheet.
For information about changing the margin, see “Top Margin (duplex)” on page 3-10.
The single test stops automatically when a single duplex sheet is printed, and the continuous test continues until 
you press Stop ().
Left Margin (duplex)
This setting shifts the image on the backside of the duplex sheet to the left or right to correctly position it on the 
page. Therefore, be sure to set the top margin in REGISTRATION before setting the duplex top margin. See 
“Registration” on page 3-4.
To set the Left Margin (duplex):
1.Select DUPLEX TESTS from Diag Menu, and press Select ().
2.Select Quick Test, and press Select ().
3.Select Single, and press Select ().
4.Hold the page to the light to see whether the left margin of the back aligns with the left margin of the front.
5.Select Left Margin from DUPLEX TESTS.
6.Use  or  to select the margin setting you need to change.
•Each increment shifts the duplex left margin by 4 pixels at 500 dpi (0.0067 inches or 0.1693 mm). 
•The Left Margin (duplex) range is -25 to + 25, and the default value is 0.
•An increase in the value moves the backside left margin to the right, and widens the left margin. A 
decrease moves the backside left margin to the left, and narrows the left margin.
7.Press Select () to save the new value.
8.Print the Quick Test (duplex) again (steps 1-4) to verify the adjustment. Repeat if necessary.

Top Margin (duplex)
This setting controls the offset between the first scan line on the front of the duplex page and the first scan line 
on the back of the page. Therefore, be sure to set the top margin in REGISTRATION before setting the duplex 
top margin. See “Registration” on page 3-4.
To set the Top Margin (duplex):
1.Select DUPLEX TESTS from Diag Menu, and press Select ().
2.Select Quick Test, and press Select ().
3.Select Single, and press Select ().
4.Hold the page to the light to see whether the top margin of the back aligns with the top margin of the front.
5.Select Top Margin from DUPLEX TESTS.
6.Use  or  to select the margin setting you need to change.
•Each increment shifts the duplex top margin by 1/100 of an inch. 
•The Top Margin (duplex) range is -50 to +50, and the default value is 0.
•An increase in the value moves the backside top margin down and widens the top margin. A 
decrease moves the top margin upward and narrows the top margin.
7.Press Select () to save the new value.
8.Print the Quick Test (duplex) again (steps 1-4) to verify the adjustment. Repeat if necessary.
Sensor Test (duplex)
This test determines if the duplex sensors and switches are working correctly.
To run the Sensor Test: 
1.Select DUPLEX TESTS from Diag Menu, and press Select ().
2.Select Sensor Test, and press Select ().
The printer displays Sensor Test Testing…. The exit sensor (the optical sensor located in the return paper 
path) and the input sensor (the optical sensor located in the back part of the duplex unit) are tested and 
reported as Open or Closed. Toggle the sensors to change the message, and verify the sensors are working 
correctly.

•Continuous—sheets are fed continuously until Stop ( ) is pressed.
Output Bin Tests
The Output bin tests setting is used to test the printer’s output bins and its sensors.
Feed Tests
This test verifies that the media from the printer’s default input source feeds to the specific output bin. Press   
to select Single, or press   and   to select Continuous. The Single test feeds one sheet of media to the 
default output bin. No buttons are active during this test. The Continuous test feeds media to the default output 
bin until   is pressed. The indicator light blinks green, and the operator panel displays [Select Output Bin] 
Feeding... while either of these tests perform.
Sensor Test
This test verifies that the selected output bin’s sensors are working correctly. The following sensors are available 
in each output bin:
Press   to select this test from the Output bin tests menu, and then press   again to select the desired 
output bin. Closed will display on the operator panel if the sensor is closed. Open will display on the operator 
panel if the sensor is open. If the wrong message is displayed, then the sensor is malfunctioning. To exit the

Configuration ID
The two configuration IDs are used to communicate information about certain areas of the printer that cannot be 
determined using hardware sensors. The configuration IDs are originally set at the factory when the printer is 
manufactured. However, the servicer may need to reset Configuration ID 1 or Configuration ID 2 whenever the 
controller board is replaced. The IDs consist of eight digits. The first seven digits in each ID are hexadecimal 
numbers, while the last digit is a checksum of the preceding seven digits. Each ID can contain a combination of 
the digits 0 through 9, and the letters A through F.
Note:  When the printer detects a Configuration ID that is not defined or invalid, the following occurs:
•The default standard model Configuration ID is used instead.
•Configuration ID is the only function available in DIAGNOSTICS.
•Unless the menu is in DIAGNOSTICS, Check Config ID displays. 
To set the configuration ID:
1.Select PRINTER SETUP from DIAGNOSTICS, and press Select ().
2.Select Configuration ID, and press Select ().
The current value for Configuration ID 1 appears with the left character or digit underlined.
3.Enter the Configuration ID 1.
•Change the left character or digit first.
•To change a character or digit, press   to decrease or   to increase the underlined value, and 
press Select ().
•To move to the next character or digit, press   or  , and press Select ().
•When you press Select ( ) on the last digit, the value will be submitted. 
If Invalid ID appears, the entry is discarded, and the previous Configuration ID 1 is displayed on the 
screen.
If the process is successful, Submitting Selection appears on the display, followed by the current 
value for Configuration ID 2.
4.Repeat the steps for entering the Configuration ID 2, and press Select ().
If the Configuration ID 2 is validated, Submitting Selection appears, and a check ( ) appears next to 
Printer Setup. 
5.Restart the printer. A POR is not automatically performed.

Fuser Temperature (Fuser Temp)
Changing this setting can reduce media curl or melting of some letterhead images. Selections are Normal 
(default), Lower, and Lowest.
Transfer
The transfer can be adjusted to Low, Medium, or High. The default setting is Medium.
Print Contrast
The print contrast can be adjusted to Low, Medium, or High. The default setting is Medium.
Charge Roll
The charge roll can be adjusted to Low, Medium, or High. The default setting is Medium.
Gap Adjust
Adjusts the minimum gap between sheets during printing. This setting reduces speed (pages per minute), but 
can be used to reduce curl of printed media and improve stacking in the output bin. 
The range is 0 (default) to 255. Adjusting by one results in 9 mm of increased gap.

Automatic Darkness Adjustment (Auto Dark Adj)
This setting attempts to optimize the amount of toner used when printing with a specific operating point. Each 
time this setting executes, the printer performs the following:
•Calibrates its toner density sensor
•Measures the reflectivity of its bare drum
•Prints patches on the drum and measures the drum’s reflectivity through the patches
•Cleans the transfer roll
•Calculates reflectivity ratios and operating points in order to attain each operating point’s 
darkness target
•Modifies the EP mechanism as necessary to adjust toner darkness.
No messages are displayed on the operator panel to give any indication that this test is running. When 
deactivated, the printer disables.
