Hi,
Thanks for posting your question ,My name isXXXXX will try to help you today.

I am giving my first solution, if this does not help, then please reply me back, instead of rating the answer.I will give you other solutions.

Please remove the toner cartridge once more and to distribute the toner evenly inside the cartridge, please shake the toner cartridge gently from side to side. If the problem persist, then follow the steps below and clean the corona wire and let me know.

1. Open the front cover.

1. Slowly but firmly pull the drum unit and toner cartridge assembly out of the machine.

Caution

• We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
• To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the illustration.

1. Clean the primary corona wire inside the drum unit by gently sliding the green tab from right to left and left to right several times.

Caution

Be sure to return the tab to the home position (1). If you do not, printed pages may have a vertical stripe.

1. Put the drum unit and toner cartridge assembly back in the printer.

1. Close the front cover.
