Dots on every paper

Every time I print something, I get these pink, blue, and light blue dots on my copies. I have a hp color laserjet 2840. I have changed all the ink and cleaned the drum the best I could. The dots are down the middle and on both sides. The dots are always in the same place and same size.

HELP!!

    I have the same problem with the dots but only in the center not the ones on the sides. Help!

    I still have the problem with the dots on my papers. If I am printing gray scale- then the dots are black otherwise the dots are different colors down the page. They are a little off center toward the right side of the paper. I have contacted HP and to date they have not given me a solution to this problem. I need help!

The magenta and cyan cartridges are leaking. The waste hoppers could be full. Usually this happens towards the end of life of the cartridges.

This is probably a registration / alignment issue. I've had a similar problem before and had to call HP and get a technician sent out to fix it. They actually ended up replacing the whole machine for me.

If it is only a blue dot then likely your cyan cartridge is bad. Try another cyan cartridge.

When printing the sheet of paper has 3 dots on the


Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.

You are spilling blue toner. Try to vacuum out the excess blue toner from the machine. Be careful not to scratch the transfer belt.
