Our copies are streaky like the drum is not clean.... help! There is black streaks on the top of all of our copies on our canon imagerunner 3300.

A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

Our Trusty steed HP 8500 has just started to print a thin twin line and other spurious marks on the top side of prints. Today i replaced the drum / fuser / other bits but no difference any ideas?

I have looked at the manual but there are so many possibilites! You can download the manual here and go to page 148 (PRINTING QUALITY PROBLEMS).

Initially I would follow the directions for clearing drum related errors:

Dark or white lines or streaks in all colors, including black.
Print the configuration page five times. The defect should clear
with continued printing. If the defect does not clear, turn the
printer off and on to reset the printer’s density calibration. If the
problem persists, replace the imaging drum. For more
information on replacing the imaging drum, see the installation
guide included with the drum kit.

Then clean the density sensor.
To clean the density sensor
Open the upper right door.
2 Use the brush located next to the
sensor to remove all toner particles
from the sensor.
You can also use a hand wipe to clean the
density sensor. To prevent scratches on
the sensor, do not use any paper products,
such as tissue or paper towels, to clean the
3 Close the upper right door.

It could possibly be a problem with the transfer drum.

I am sorry this is not of much help!

Grey background and dark streaks

Change out the toner first and then the drum. Also be sure there is not excess toner underneath where the toner is installed. If so clean that out with a dry cloth.

Black smudge streaks on rightside of printed/copied material

Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.
