1. CE Mode (Diagnostic Mode)

On most models of Dell Laser Printers it is possible to boot them into a diagnostic mode, called CE Mode, in order to troubleshoot the internal components in the system.

CE mode is broken into several sections:

  • Parameter: Provides a life counter for consumable components as well as a complete page count.
  • ESS Diags: Tests functionality of electronic components and controller elements, such as Operator Panel functionality.
  • Print Info: Provides detailed settings pages.
  • Test Print: A large variety of colour test prints allowing you to diagnose each toner/toner developer individually as welll as testing alignment (print skew issues).
  • IOT Diags: Digital Input - Tests individual Sensors (useful for diagnosing paper jams and other hardware failures)
    Digital Output - Test individual Motors and clutches (useful for diagnosing paper Jam and paper feed issues)

On the C2665dnf / C3765dnf there is also an additional section for Scan/Fax Diagnostics.

2. Booting into CE Mode

C2660 / C3760n / C3760dn :

  • Hold down the left arrow, right arrow, and Menu buttons while power the printer on.
  • When prompted for a password, press up, up, and OK.

C2665dnf / C3765dnf :

  • Hold down the 4, 5, and 6 buttons while powering the printer on.
  • When prompted for a password, press 2, 2, then 5. Then select Printer Diag.

The two most common uses for CE Mode will be running Digital Output Motor and Clutch Tests to determine jam issues.

For an explanation on running diags on Motors and Clutches please use the guide below:

3. IOT Diags

 

Digital Output:

Running Motor and Clutches on the C2660dn / C2665dnf / C3760n / C3760dn / C3765dnf for diagnosing Feed / Jam / abnormal noise issues can be performed by following article: SLN284346 "How to Troubleshoot Abnormal Noise Issues on the C2660dn / C2665dnf / C3760n / C3760dn / C3765dnf Dell Laser Printers":

  • Select Printer Diag.
  • Scroll down until IOT Diag is displayed and Select.
  • Then select Digital Output.
  • set 041-001 to EXEC (ON) by pressing the Select (Tick) Button.

This Motor must be left at EXEC for the other motors to run correctly to allow accurate diagnosis.

Scroll Down to 071 001: Main Motor and Press Select (Tick) To Turn to Exec (ON)- You should now hear the main Motor.

SLN287099_en_US__1icon NOTE: To Turn off any Motor or Clutch press the X button.

Digital Inputs:

Digital Input checks whether the digital input (DI) components function properly.

The display shows [0] when the digital input test is started, and the value will be increased when the DI components are switched from OFF to ON, which is used for confirming that the component functions normally.

The test targets all DI components (sensors).

4. Paper Feed Tests

 

In CE Mode you are also able to run manual feed tests, allowing us to accurately pinpoint the motor or component that is failing and causing a jam.

This is done by booting into CE Mode, as described above then:

  • Select Printer Diag
  • Scroll down until IOT Diag is displayed and Select.
  • Then select Digital Output.
  • Set 041-001 to EXEC (ON) by pressing the Select (Tick) Button.

This Motor must be left at EXEC for the other motors to run correctly to allow accurate diagnosis.

Then turn on each Motor in sequence to feed the paper through the printer.

Tray 1 Feed Test

6. Digital Input Feed Sensor Tests

Digital Input checks whether the digital input (DI) components function properly.

A paper jam error may occur if one of the sensors are stuck or damaged.

The guide below shows the most likely sensors for any jam or feed issue and how to test functionality.

Registration Sensor:

DI: 071-103

The Registration Sensor identifies whether paper is jammed internally when pulled from the Tray or the MPF.

In order to test the Regi Sensor:

  1. Boot into CE Mode and go to the Digital Input Tests.
  2. Open the Back Cover and remove the Fuser Unit.
  3. With the door open, the Regi Sensor can be seen on the bottom half of the Printer, shown below.
    SLN287099_en_US__13exit sensor and reg sensor
  4. Turn on the sensor 071-103.
  5. The LCD display will show 071-103 L0.
  6. Use your finger to move the Regi Sensor, every time you move the sensor the counter should change.
    SLN287099_en_US__14reg sensor count
  7. The change will be registered in the following way:
    L0 -> H0 -> L1 -> H1 -> L2 -> H2... (L: sensor closed, H: sensor open)
  8. If the counter does not move up then there may be some damage to the sensor or the controller card in the printer.

Exit Sensor:

DI: 071-104

The Exit Sensor advises the Printer that paper has entirely left the printer and a job is complete.

In order to test the Exit Sensor:

  1. Boot into CE Mode and go to the Digital Input Tests.
  2. Open the Back Cover and remove the Fuser Unit.
  3. With the door open, the Exit Sensor can be seen on the top half of the Printer, shown below.
    SLN287099_en_US__13exit sensor and reg sensor
  4. Turn on the sensor 071-104.
  5. The LCD display will show 071-104 L0.
  6. Use your finger to move the Regi Sensor, every time you move the sensor the counter should change.
    SLN287099_en_US__16reg sensor move with finger
  7. The change will be registered in the following way:
    L0 -> H0 -> L1 -> H1 -> L2 -> H2... (L: sensor closed, H: sensor open)

If the counter does not move up then there may be some damage to the sensor or the controller card in the printer.

If these steps do not correct the problem, please contact Dell Technical Support.
