Win XP/SP2, HP Deskjet 840C, newest drivers.
When I print say a picture there are thin horizontal white lines about 1/4"
apart the whole way down.
This is even after changing the colour cartridge to an original HP and
properly aligning it via HP Toolbox.
Is this serviceable or is it a sign of wear in the rollers or moving parts?
Would like to get it going for another while especially since I've just paid
£21.99 for a new cartridge.
Replies appreciated.
 
With the printer power off, open the cover and you should see a clear
plastic strip (ribbon) near the back.
Take a clean dry cloth and gentle wipe the strip to remove excess dried ink.

Thanks for the reply, will try that.
Should have added that it prints plain black text OK which is why I changed
the colour cartridge.
