2.


Horizontal deletions or banding Diagnostics


Horizontal Deletions or Banding can be caused by a build up of Toner on one of the rollers in the Printer or damage to a component.

In order to diagnose a Banding Issue, please follow the steps below:

1. Verify that the Paper Used is within Specification

See Article:
Print Media and Specifications for the Dell c3760dn, c3765dnf Laser Printer

2. Clean the Printhead (ROS) Window

See Article:
Cleaning the Printhead (ROS) Window on a Dell c3760dn, c3765dnf Laser Printer

Turn off the Printer and Boot into CE Mode to print a series of colour test prints, to identify whether issue is present on all colours or just one:

For information on CE Mode See Article:
CE Mode (Diagnostic Mode) on the Dell c3760dn, c3765dnf Laser Printer

Please Print the Contamination Test page:

The Contamination page prints out all 4 colour 20% pages

Cyan 20%

Yellow 20%

Magenta 20%

Black 20%


NOTE: The 20% Tests will print out an individual sheet of each colour at 20% saturation allowing us to determine if that colour is outputting correctly.

It will also Print a 5th page containing information on roller sizes within the Printer. This can be used to determine the distance of the repeating deletion and can indicate the consumable component with the defect.

3. Using the 20% tests, determine if one or all test Prints are blank or very faint:

4. If only one colour displays the PQI continue below:

-> Determine whether a Dell Branded Toner is in use

Note: It is recommended that only Dell Branded Toners are used in Dell Laser Printers as Dell cannot guarantee compatibility or the print quality of any 3rd party toners.

-> Try a working Dell Branded Toner from a working Dell c3760, c3765 Laser Printer (if available)

-> If the issue is resolved with a working Toner, please advise Dell Technical Support that you require a new Toner, via the
Twitter Contact option.

NOTE: If you were not using a Dell Branded Toner and would like to purchase one, please go to Dell.com http://www.dell.com/supplies and select the Toner you require for the correct model

5. If all colours display the PQI, when printing test pages, use the 5th page of the contamination test to provide an indication of the point of failure. If a part has been indicated, please try swapping that component with another working component from another c3760/c3765 Laser printer.

If you are unable to determine the component, please continue below:

-> Try another Imaging Drum from a working Dell 3760, c3765 Laser Printer (if available) and Print another series of Test Prints

For detailed information on removing and installing consumable components on these Printers, see article:

Replacing the Consumable Items on a Dell c3760dn, c3765dnf Laser Printer

-> Try another Fuser Unit from a working Dell c3760, c3765 Laser Printer (if available) and Print another series of Test Prints

-> Try another Transfer Roller from a working Dell c3760, c3765 Laser Printer (if available) and Print another series of Test Prints

6. If you have replaced and identified the component causing the failure, please contact Dell Technical Support, using the
Twitter Button, advising of the issue and parts required.

7. If you do not have any replacement components to test with, please try a Stop Test on the Fuser Unit.

For detailed Instruction on performing a Stop Test, see article:


Performing a Diagnostic 'Stop Test' on a Dell c3760dn, c3765dnf Laser Printer

8. If the PQI is seen only after passing through the Fuser Unit, please contact Dell, via the Twitter Button, to advise of a fault with the Fuser Unit.

9. If the PQI is displayed before passing through the Fuser Unit, please contact Dell, via the
Twitter Button, to raise a Technical Support Ticket
