I have watched a few videos on the carts, apart from aiding to
dismantling and cleaning the cart they still dont solve the issue.
Tonight I printed 16 pages and all had slight ghosting on right hand
side.
Away doing some other things turn printer off, an hour or so later I
print 4 postage labels and the pages are perfect (no ghosting)
Its the inconsistency that I cant understand.

Over the years, I have operated the same reliable HP 4M+ printer.

I have had this exact effect on a number of occasions. In every case it
was caused by a faulty toner cartridge (but remember that quite a lot of
the 'works', e.g. optical drum, corona wire) are inside their cartridges.
In most cases, I think they were 'old stock' cartridges. Reputable
remanufactured ones work fine.
