Try scanning the same document in two diff brightness levels (in B&W, say one at 75 and other at say 210. I am assuming you are using CapturePerfect. If the black streaks are same in both the images, then it could be scan module problem. If the streaks vary in size, then it is definitely dirt on the glass. use isopropyl alcohol (rubbing alcohol) to clean the glass. DONT USE solvents. S. Mohan, Chennai, India

Black streak on scanned printed copies


Hi

Open your scanner lid and make sure their is no dirty marks sitting on your scanner glass. Also does this happen on the scanner glass or when using the ADF? If its on the ADF its most likely that the glass is dirty and needs to be cleaned. 6c66c542-b5d2-4d0a-8a21-00c054973a29.png

Clean the thin glass strip that sits to the left of the flat bed glass.

That is the glass used when the ADF is being utilized.
There is dirt on it causing the black streak.

Hi, My Canon 3245 Imagerunner is streaking.


Hello,
First, the streaks appears when copy from glass or adf, when printing or all?

Solution #1:
How many copies did you do from last drum changing? if over 80 000 copies, replace the drum unit.
-in case that streaks appears when copy and print

Solution #2:
If the streaks appears only if you copy from adf or glass, clean the glass and dry it out. Both glasses, narrow on left side beneath the adf/cover and glass for copy of original.

Solution #3:
If the streaks are wide and solid, with possible toner left overs, you need to replace fixing film.

Hope that helps!

Horizontal streak


Clean the scanner strip glass. This is the small strip of glass that is just to the left of the large main glass. This is the only cause for black line (s) when copying using the ADF(top feed). If prints or copies fine from the glass then it is this strip glass needing to be cleaned.

The scanner leaves a black streak on page only when in duplex mode. I have cleaned and cleaned and cleaned the parts the manual suggests and the streaks are still there.


Check if the glass is scratched. Try scanning in two different brightness levels. If the size/thickness of the streak varies and is also with 'steps' (when zoomed) then it is glass related. If the streak is same thickness and crisp at ends, it could be Scan module problem.

I have a black streak all on one side when i copy ?


If it is just when you copy and not when you print then it is a cleaning issue. Toner cartridge would cause the line to appear on copies, printouts and faxes. There is a piece of glass inside the auto document feeder that is probably dirty. Open up the document feeder as if you were clearing an original document jam. Look for a piece of glass inside the ADF, it will run the length of the document feeder. There is probably some dirt or another popular problem is white out. Clean off the glass with glass cleaner or alcohol and it should fix the problem.

Black streaking accross the print even after i clean the glass


Things to check.
Check the **** glass that the originals go across when using the doc. feeder. If it has even a spot, this will cause a streak.

Check the drum to see if the line is on the drum, if it is you may have a bad drum cleaning blade.

There is a corona cleaning device just above the drum that you can pull out and push in to clean the wire/comb. This too can cause a black streak.

Hope this helps

HP Officejet 6300 All-in-one machine makes black streaks


The problem is that that there a small piece of glass that the doc feeder use's to scan the orginal. You will have to clean the small glass it's about a half of a inch piece and is normally under the doc feeder unit. It will either be to the right side of the main copy board glass or it is under the doc feed unit where the paper goes down through the feeder. It is mostly some white out on the glass, just clean with a dam cloth with water or windex..... Good Luck
