Measure the distance between the original image and the repeated image. A measurement of 56.6 mm indicates the fuser needs replacing. Before you buy a new fuser, check the firmware version of the DC Controller.
You can do this by printing out a config page. A configuration page can be printed from the printer control panel (press the green Select button, then press the left (<) or right (>) buttons to navigate to the Reports menu, press the green Select button - press the left (<) or right (>) buttons to navigate to Config report and press the green Select button).
At the bottom of the printed configuration page a line beginning with CPR and then a group of numbers followed by EV= will be shown. The latest DC Controller firmware (1.47) will show as EV=2F.
If the value of EV is lower than 2F, such as 2A, you need to update the DC Controller firmware.
This is the HP description of the fix for this firmware update:
Corrects fuser offset (ghosting) that typically appears on the first print jobs after the printer has been idle for several hours. The offset or ghosting typically appears on the left or right margin but is not limited to those areas.
For some reason, HP have removed the firmware file from their website. You can still find the Mac OS X version on HP by searching for it. You can find the Windows version elsewhere by searching Google for 2600_DCC_FW_Update-14701.exe.
Or you can download the Windows version by clicking the following link (you will have to unzip the file):
This is the version I use, and have used recently, so it works and shouldn't contain any viruses.
You need to have the printer driver installed on your computer to run this update. Simply run the program and select the printer to update in the box that opens up.
DO NOT POWER CYCLE THE PRINTER during the update process or it may leave your printer in an unusable state.
During the printer firmware update, the LCD display on the printer control panel will display "Initializing" and the green and amber LEDs will begin flashing. After several minutes the green and amber LEDs will go solid and the printer will make a noise as if it is warming up. The display will then change to " Turn off then on". At this point it is necessary to power off the printer and then power on again.
Print out the config page again to confirm that you get EV=2F and your ghosting problem should be fixed.

Posts like these do help people like us who are into servicing. Most of the time ghost printing issues are caused by drum. Sometimes cleaning the drum and the printer can solve the issues. I have been working in hp service center and these issues are quite common. Anyway good post to upgrade our knowledge.
