HP DJ 5500 unwanted double image dark text only

[Guest]

Hi, Does anyone have any idea why I am getting a double image only on the dark text (brown, black, gray) when printing any type of file (usually jpgs) on my HP5500.
do you think this has anything to do with print head seating or if something needs cleaning. Thanks!

Paul,
Is the problem I asked about specifically addressed in your manual?

what version of the pcl driver file are you using. try the one below or above the one you are using. let us know.

Also did you do the machine diagnostics test to check internal engine quality. This will tell you if you have a driver or hardware problem.

I am thinking black printhead.

I replied to this thread earlier and realized that it was a designjet which i do not service. However, i looked at the service manual and found this entry here as below. also to repair this machine you MUST have a service manual as this has lots of calibration procedures ect that you must follow exactly.

How to Use the Diagnostic Print

What is the Diagnostic Print?

The Printer contains an internal Diagnostic Print to help youdiagnose the possible source of any print quality defects. TheDiagnostic Print is divided into five numbered parts:

1

Primary colors specifically designed to diagnose banding problems.

2

Color to color alignment.

3

Bidirectional alignment to check alignment when printingbidirectionally.

4

Vertical line straightness.

5

Nozzle print test to check each Printhead nozzle in a Printhead.

Considerations for Printing the Diagnostic Print.

1

The Diagnostic Print requires A2 or C size media so you must havemedia loaded (roll or sheet) that is this size or larger.

2

Use the same type of media that the customer was using when theyexperienced the print quality problem.

3

Use the same print mode the customer was using when theyexperienced the print quality problem.

4

If the customer is using non-HP media and after the Diagnostic Printyou still have the same print quality problems, change to genuineHP media and repeat the Diagnostic Print.

5

Study each of the test patterns in the order that they are shown i.e. 1through 5.

6

If you do not see any problems with the Diagnostic Print, then theproblem may not be with the Printer itself. The problem may bewith the RIP or the driver for example.However if you do see problems with the Diagnostic Print thencontinue with the following procedures which will help you to

diagnose the problem.
