HP Laserjet 2300 printing faint / white stripes on page

Hi,
Wonder if anyone can help;

We have a HP Laserjet 2300 that prints very faint / white stripes down the page.

I have changed the fuser unit and changed the print cartridge.

It works fine then gradually a faint line appears which grows and grows to almost the full width of the page before the printing dissapears altogether and its basically just a white strip.

If I change the toner catridge the above process will repeat - i.e starts off fine then gets faiter and fainter. It usually only needs about 10 - 20 pages to be run through until the whole page is white.

Any ideas as to what else could be causing this?

First - are you using genuine HP toner cartridges?  I know, that usually sounds like the manufacturer's copout - but the newer HPs really don't like off-brand toner cartridges.

Here is what HP says on your issue for the 2300:
    *      Print a few more pages to see if the problem corrects itself.
    *      The toner supply is low or out. If low, temporarily extend the print cartridge life by redistributing the toner. If out, install a new HP print cartridge.
    *      The media might not meet HP specifications (for example, the paper is too moist or too rough). See the User's Guide for information about media specifications. If the media does not meet HP specifications, replace the media.
    *      If the whole page is light, the print density adjustment is too light or EconoMode might be on. Adjust the print density and EconoMode with the software driver. For non-Windows operating systems, this feature is also available in HP Web Jetadmin.
    *      Turn over the stack of media in the tray. Also try rotating the media 180 degrees.
    *      If these steps do not resolve the problem, click here to go to the HP support Web site at http://www.hp.com/support/lj2300.

The first two of those I'll ignore, as you're already past them.  If the next three don't work, try the following:

Do a thorough cleaning as described here:

Otherwise your problem is most likely in the laser scanner assembly.  You can try taking the unit apart to get to the laser scanner, then cleaning the lens (glass cleaner and a lint free cloth).  This breakdown shows its location in the printer:

Note that the parts breakdown is for the US model.  I'm assuming you're not in the US, based on your time zone, so you may want to start back here:  http://h20141.www2.hp.com/hpparts/partsdirectory/  and get to the breakdown for your specific area.
