Color smudges after refilling laser printer Ink

[gtslabs]

I have a HP 8550GN laser printer with duplexer. I went the cheap route
and refilled my cartridges. I must have had some bule ink dust residue
because whenever I print in color I get blue smudges on the paper. But
when I print in Black only I dont see the smudges. What can I clean to
remove the blue smudges?

It looks like the cheap route was not so cheap.

Much like cheap internet access, anyone can play......

Do the smudges repeat down the page? If so what is the vertical distance
between the beginning of one smudge and the beginning of the next smudge?

If the toner powder used is not the proper type for your printer (wrong
melting temperature, wrong toner power size, type of particle, etc.) the
toner may be reacting poorly with your printer. It may not be due to
spillage or residue, but just a toner with inappropriate characteristics
for your printer.

It might not be spilled blue toner, I assume there is a scavenger blade
in the blue toner cartridge. When it fails to remove surplus toner from
the drum you get smudges.
It's a common fault with mono lasers and the only cure is to replace
the cartridge.
If it's spilled toner then it should gradually fade as the surplus toner
is used up, if it's the scavenger blade it will get steadily worse.
If it's the scavenger blade it is possible that the after market
non-OEM toner is of unsuitable (for your printer) composition
(too fine a powder might not be scavenged, may be abrading
the scavenger blade etc.) Like inkjets some aftermarket inks
create problems with some printers, poor color balance, wrong
viscosity, clogged heads etc. So generic aftermarket inks or
toners are a gamble, for many users they work fine.
If it's a clapped out 10 year old printer then try aftermarket
generics, it's not worth the arm and a leg price for OEM.
