Paper comes out with lines & darkness on the right side only

SOURCE: black line on left side of paper

It sounds like a cartridge issue. Try changing the cartridge.

SOURCE: vertical dark/smudged line on right

See its a very common issue.the right side of the drum has moisture on it.remove the toner and drum and apply a hot air blower on it for some time also clean the printer internally.reinsert the toner and drum.
check by printing few pages the smudging on the right should go within 10 to 12 pages.
if the smudging doesnot go away then its time to replace the drum to solve the issue.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Most likely this is the drum. Take a damp cloth and clean the top of the drum roller. This should fix the problem. Good Luck.

Drum Cleaning Blade failure. Open up the top half of the machine as if you were removing a paper jam. Now look under the top half and about in the center from left to right. You should see a burgundy colored cylinder running from the front of the machine to the back. If you can see the toner streaks on the surface....expecially on the 1/3rd like on the copy then this will be proof that the drum cleaning blade is the cause. Simple repair for a tech that knows copier basics. A good estimated cost would be about $25.00 for the blade and whatever the going rate is for a service call in your area.

There are a number of things that can cause this problem, below are a few things you can try.

1. Remove the process unit out as if you were going to remove a jam. There is a green piece of plastic used to clean the main charge unit. Slide it to the left then back to the right. Make sure it is seated all the way to the right in it's home position or it can cause black lines.

2. If you have a document feeder on the copier is the line only when using the document feeder?
- Determine if it is by making a copy from the glass.
- If it is only when making a copy from the document feeder then clean the small **** glass just to the left of the large glass. This glass is used only when making a copy from the document feeder.

3. If you wipe your hand across the copy and the toner wipes off then fixing unit should be replaced.

I hope this is helpful,
