Hi,

There are 3 parts to the imaging process that could cause your issue. You have the toner (x4), the imaging drum unit (Q3964A) and the fuser unit. If you are getting streaks from all colors, one or more these parts are the issue.

Let's start with the easy stuff:

Open the cover as if you were replacing toner where you can "visually" inspect the toner and imaging drum. Pull the drum out and pull back the "plastic shutter" on the top, this will expose a green drum CAUTION! Too much exposure to light and touching it can cause damage. Just take a quick look trying to see if any of the lines on your page match any marks on the drum. Check the bottom half of the unit as well there should be a white section across the bottom, expect that as well.

Next look at the toner, if you can look at any other color but black it will help you look for the streak marks a lot easeier. If you couldn't see any streaks on the drum on toner cartridges, it's time to look at the fuser unit. Power the machine down and turn it around, unplug it then fold down the blue clips and CAUTION! the fuser heats the toner to the page so if it's been used recently it may be hot. once the clips are down, just pull straight back and look for the streak marks.

Sorry for the book, but I hope it helps.

SOURCE: My drum is at 40%. I have black vertical streaks

I was going crazy! Had a tech come in and look at the machine - needless to say he did NOTHING! A friend came over and was trying different things. It was that the "rack" that the toner cartridges sit in was not fully seated - once he pushed down a little and heard it "click" I had no more black streaks. AMAZING

Fuser sleeve is contaminated and needs replacing - cheaper to replace the printer.

SOURCE: I get a light gray

Try cleaning the wire grid- sounds like you have some gunk on the corona wire- in the printer under the toner cartridge is a wire grid that charges the paper before toner is applied- if there is gunk on those wires, you will get the smudge you described. You may want to use an antistatic brush and you *WILL* need to remove the power from the printer. Also, if you have one, a vacuum approved for both ESD and capable of vacuuming toner- don't use a standard shopvac, bad things like toner stuck in the motor of the vacuum and causing fire may occur. Fair warning, be prepared for something nasty- last time I had an issue similar to that ended up with me pulling a toner-caked, extra-crispy palmetto bug (Think of your standard cockroach, then triple or quadruple the size.) out of the corona wire.

Balck and white streaks on left side of paper


Usually if there are streaks you need to change the pcu that is the same color as the lines. If the streaks are gray it also could be the fuser, but i would think it is the pcu.

If the colors are good and solid with no fades, only black streaks, then black is the culprit. I suggest replacing the black cartridge.

My rep advised that if this problem is occuring when using the feeder, the small glass strip to the left of the glass can have some sort of either high lighter or white out stuck to it. He suggests cleaning this with some alcohol.
