Ghost image When printing, on the right side of the print is a ghost image repeating along the entire side.

Most of the cases fuser assembly or supplies are causes of ghost image. If image is not properly transferring on media causes transfer roller or ETB.
Do this small exercise: Give print command, wait till paper grabs, once paper entered in cartridge area, power it off, open top & front cover, remove paper and see the print quality.Observed any ghost image what you observed? No ghost image? then problem with fuser assembly..

1.Remove fuser assembly, check any toner particles deposited on surface of fuser transfer roller or heater roller.. if found clean carefully with good cotton cloth while fuser having certain temperature,pl avoid metal & sharp objects to clean..
2. Clean paper path roller(You can observe the rollers to push the paper to reach the destination)
I hope this exercise will resolves the issue..

Ghost images appear on the printed page because of bad cleaning blade or improper charging of the drum unit. Ghost images appear on the next printed page if cleaning blade does not clean the drum surface. Drum/ photoconductor is very sensitive to light, so special care should taken while pulling it out.

Run a half test. While printing a few pages, open the cover, pull out the toner and look down at the paper. If you see the ghost images replace the toner. If you don't see the ghost images, replace the fuser.

The "ghost" image is "burned" onto the drum.

A laser printer is supposed to charge specific "dots" on the drum, and the toner-ink is supposed to stick only to those "dots", the paper is pressed against the drum, and then the "fuser" uses heat to "melt" the toner-ink onto the paper, to produce the printed page.

You need to replace the drum.

the ink carrier was dirty already

i would say ghost image is more likelly your imaging drum.

some printers have the imaging drum built into the cartridge some have it separate.

i would say try another cartridge

also don't trust remanufactured cartridges if you are concerned with print quality.

Is it a ghost of the image or just a repeating defect? In the menu, there is a repeating defect information page that you can print out. Depending on the spacing of the defect, you can determine which component it is.

sounds like a bad drumbur also can be caused by a defective fuser.

This can be caused by one of two things.

1. faulty wiper blade on your toner so that the previous image in not being wiped off the drum.
2. worn fuser sleve.

To work out which it is you will need to do a half stop test: print off a normal document then when it is about half way through the printer ( unfortunatly you may have to repeat this to get the timing right) open the front cover. remove the toner cartridge. if you can see the ghosting on the page the it is the toner. if its not there then its a new fuser. to save on money and if your confident enouh you may be able to just chane the fuser sleve depending on the state of the fuser on a whole.

hope this helps

I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
