Hi there,

- Open your cartridges, take a sheet of paper, and carefully slip the paper into the Toner hole from side to side to clean the 'Residu'
- Shake your Toner horisontally
- Take a dry cloth and clean the 'Mirror' inside the Printer. (you can see it from outside)

try to print some paper again,
if this problem still exists,
Check your 'smudges', is the position exactly same from one page to another page???
If the 'smudges' has the same position, maybe, your 'Laser Mirror' (this is different with the first mirror') is dirty.
If you want to clean it by your self, you must open all your printer casing, and find the 'Laser Mirror'.

Good Luck!!

Thanks

It's al black horizontal lines/smudges over the printed page. How to cean this?


Black Horizontal Lines are normally caused by a Light Burnt Drum.

The drum in built into the toner cartridge for this machine so replacing the cartridge will fix the problem.

Two faint white horizontal lines


the white ghost lines are down to the charge wire within the toner cartridge being dirty, the only real way forward is to replace the toner cartridge as access to the charge chorona wire is not possible without ruining the cartridge itself

The printer is printing duplicate text in other areas of page randomly


If the duplicate text is faded or a "ghost" image from higher up on the printed page then your fuser film is going bad. I would try a different toner cartridge first just to eliminate that as a possibility but it sounds like fuser film. You can get a new fusing unit or see if a printer/computer service company local can replace just the fuser film. It is about 50% cheaper to do just the film as the rest of the fusing unit is good.

Horizontal lines and smudges across the page at 1.5" intervals down the page.


Judging from the distance between the lines, you probably have a defective cartridge. Smudges are generally caused by a defective fuser, which means it's time to send the printer out for repair.
