Np 6412 copy dirty lines length of paper

Sounds as if the drum needs to replaced. How long has it been in the copier? They are supposed to be good for 30,000 copies or one year. It could also be dirty optics ( mirrors and glass ). Drum is easily installed by the customer. Just practice with the old drum - removing and re-installing before using the new drum. Too expensive to damage when installing. **** open the copier, Look under the control panel and you should see two levers. Move the right one to the right - this moves the developer away from the drum. Then move the left one down and this releases the drum for removal. Reverse procedure and power up the copier. It will automatically run and set the new drum settings into the copier.

To replace the Canon GPR-11 black drum, do you just take the old one out and put the new one in? That is what we did and there is a band of black toner printing on the top of each sheet.

The new toner cartridge snap's into the top of the Hopper > just look on the box on how to install it. Once you have pulled the tab till you can read "STOP" push the slid back in and release the toner cartridge and you are done...... Put the empty cartridge into the "G" file

How do you replace toner for canon np 6035 copier

Close but the toner container is replaceable, you do not have to pour any toner in the container. The replacement toner should be the exact same toner bottle, all you have to do is just swap out with the old one.

The Waste Toner is located in the the drum unit it self. You need to remove the drum unit & on the top of the drum unit is a white or clear rectaular cap. You need to open it carefully and vac out the toner in side the unit. FYI if you are empting the waste toner the drum is just about worn out... Good Luck

Cartridge is defective. I suspect it was a 'compatible' or remanufactured unit vs. an original. Replace it and it will work fine.
