Thanks, doesn't really show enough, I'm familiar with photocopiers which
have completely seperate toners and drums (as very old lasers used to) but
they usually seem to all have doctor blades on the drums

Most, I think all, HP monochrome (Canon engines) lasers have integrated drums
and toners. The Doctor blade in these ensures the magnetic sleeve has the right
amount of toner on it and the drum is cleaned by a Wiper blade (using Canon
terminology) and deposited in the waste toner hopper. Brother lasers use
seperate units and the waste toner is deposited back into the the main toner
hopper unlike Canon engines, this causes the gray background on Brother lasers
when the toner is very low.

I just recently refilled my laser toner on my HP1020.
Some of the toner went onto the drum and now when I print there is a
greyish hue to the whole paper. It seems as though there's still stuff
on the drum.
How Do I clean the drum?
Is there a program or something I can do on the computer to clean it?
Thanks
Jeff

No, there is no program. The best thing to do would be to very
carefully wipe the drum down with a lint-free cloth.

You cannot do this from the PC.
If the drum has toner on it that does not wipe off during printing then there
are two possibilities.
1. The drum is failing and the toner is stuck to it (happens with age).
2. There is a problem in the other half of the cartridge, either the wiper
blade has failed or the waste hopper is overflowing.
Is this the first time the cartridge has been refilled? Can you see the toner
on the drum?
If you wipe the drum with a lint free cloth you risk removing the lubricant
that is on the drum, if you are careful it should be OK. If it wipes off and
then the problem returns then see 2 above. These cartridges have very small
waste hoppers and to refill them succesfully it is desirable to empty the waste
hopper. Also, they will not withstand more than one refill without other parts
nedding replacement (Drums fail first). As always keep the drum away from light
as much as possible.

Is this occurred rather suddenly after the refill, and it has not
resolved after a couple of page through, this is likely not a matter of
cleaning the drum, but more so use of a wrong toner formulation (wring
type or size of grains, etc.)

Most laser printers have a wiper blade that cleans excess toner off the
drum with each revolution of the drum. Spilled toner would be removed
and dumped into a waste bottle or recycled, depending upon the machine
in question. However, if too fine a toner, a toner with the wrong
electrostatic characteristics was used, that may cause it to stick too
well to the drum, for instances.

Sometimes you can program the printer to run extra cleaning revolutions
per page to clean it better. Also, if the drum was exposed too much
light during refilling, that can damage the drum, usually making it less
sensitive.
