We have a relatively new drum, colour cartridges are OK, we have a new Printer belt and I have cleaned the glass under the drum. I still have 2 white vertical lines running through each and every colour printout- very noticeable. What else can I do? The 2 lines virtually divide the page into 3 equal parts.

If the line is across the page and at regular intervals this is usually a mark on the drum / web or cartridge drum - can be residue from printing labels (especially if you reuse sheets). If it is a particular colour then it is likely to be that cartridge which has problems.
If line is top to bottom of page then this will be either excess toner in printer or faulty cartridge - again if the line is a particular colour look at that cartridge first.
Is it un even vertical line on media?.. observe which colour it is, replace the cartridge.Reason: Cartridge drum rotation is not in proper manner while image formation( jerks in rotation) result vertical line on media. Most of the cases cleaning blade causes of the malfunction, if you can shoot the problem do it or else replace the cartridge.Pl avoid to handle the drum surface with bare hands as well as don't expose the drum under the light.
print out is basically due to cartridge related issues. Take out the
cartridge and clean its drum/ (green roller) with a dry, soft,
lint-free cloth. The drum is usually located under a cover. Checkout for
any spilled toner inside the printer and clean it also. Print a few
pages so that the parts get further cleaned. I think, this would solve
the issue. (This may help temporarily)
(thicker lines) and dots etc indicate faulty PCR Roller which is located
green drum inside the cartridge. So, it is recommended that you replace the cartridge with a genuine one (not any replacement or refill).
Let me know if any
further clarification is required. Hope it helps! Good Luck! CreativeTECH
check your drum unit. The toner cartridge mounts into the drum which can be permanently charged causing a constant streak to occur.
Solution: Remove the toner and drum unit. Clean them off with a non-fuzzy non-rough cloth or paper towel. Pay particular attention to where the streaks are in relation to the toner cartridge and drum. If you clean it off and you still get streaks check whether they transfer from the toner or just from the drum.
There may be a way to discharge the drum, otherwise you need a new drum.
Depending on the type and model of your printer this could be several things mostly related to the cartridge or drum if you have a separate toner/drum system.. Since you have stated you have shaken the toner, I am assuming you have a laser printer. New belt, has me confused. Green thing leads me to think you are talking about the drum. If so, did you purchase a new toner cartridge or new drum cartridge?
Several components inside the toner or drum cartridge will cause vertical streaks. It depends on where these streaks are occurring and how wide the streaks are. We call these repetitive defects and they can be measured to determine which part is at fault.
Also, if this is a multi-unit machine (print/copy/fax/scan) Check the platen glass or ADf feed unit for white out. That has been a major culprit of vertical streaks on the page.
More specifics about the model of machine and cartridges being used would be helpful in trying to solve this problem for you.
If the line is white (no toner is added in
that area) check the laser head glass which is located right below the drum.
Remove the drum and you should see it below a narrow strip of glass. Just be
sure to be clean, with no dirt, toner or pieces of paper on it.

pleas take a closer look at the pc drum and transfer belt, if there are also stripes then you find a problem, stripes on pc drum means new pc drum and on TBU there is possible to clean the cleaning unit but not in every case. if cleaning doesnt help new TBU
