Scanners can be taken apart to be cleaned:  'You want to clean the inside?' 'Well, its dirty ikayak, thats why.' Ok take it apart, remember the screw sequences; that aint hard normally for scanners.
Put it this way there aint any little brushes or nanobots to clean it for you in there... you gotta do it manually. Use something alcohol based to lose smears and actual residue. It its dust then use a hairdryer and a soft SOFT brush that doesn't have any dust on it itself... you'll just make it worse.
I hope your scans are clearer now!

How to clean the underside of the glass in a HP scanjet 2400

Hi ,
You probably already found this :
According to it , you should normaly contact a HP technician to have the job done . Nevertheless , I succeeded to clean the underside of the glass inside a HP Scanjet 5470C wich seems similar to your model 2400 . If you take of the lid of the unit , you should find two screws in the opening of the hinges . Unscrew them and lift up the the whole top of the unit . You might encounter somme kind of resistance during the operation but I finally succeeded to get the it free that way .
Best regards .

Scanner produces streaks

It's possible that the black lines you're experiencing are an internal image adjustment issue with the scanner itself. If the scanner glass is otherwise clean, try going to the Canon DR2050/2080 utilities installed as part of the set up of your scanner and running the Adjustment Tool - it asks you to place the "adjustment paper" in the scanner. The term, "adjustment paper," appears to mean anything which has an image or text on it. Be sure you clean the scanner first before running this utility. It will have you put the "adjustment paper" through twice, and that in turn should remove the black lines in your scans, as long as there is no dust on the scanner glass. Office Depot sells cleaner sheets for laser and inkjet printers which also work on faxes and scanners and which will clean the glass for you.

Can't remove the glass on my Canon 8000F scanner to clean the underside. I've removed the screws under the lid and the 2 from the bottom. Is there a way to remove the glass?

What you will need
A - magnetic screw driver
B - glass cleaner
C - Flat blade dinner knife the sort that where around 30 to 40 years ago with the plastic ivory looking handles they have a round edge at the end that type
C - Patience

To clean the platen on the Canon 8000f
1. Take the lid off
2. At the bottom of the post holes remove the 2 small screws
3. Turn scanner over and remove the 2 screws underneath
4 this is were patience comes in and the flat bladed knife insert the blade at the corner and twist gently you will notice at the back centre 3 clips holding the black section of plastic in place the black plastic cover shoud pop off with gentle twisting of the knife blade
5. Whe the black plastic cover pops it's then a matter of sliding the platen backwards.
6. Clean glass with Amway Cryastal Clear or Windowlene
7. Then work backwards to replace the parts magnet screw driver is a help here.
8. Done
9. I figured that if you break the tabs being a bit to heavy handed don't worry because its held in place with 4 screws and the way the plastic is designed
10. Patience is the key as well as those plastic clips at the back.
11. Oh and don't forget to unplug it first
12. A nice clean Scanner
13. Had a problem with loading the latest software from Canon (Win7)drivers it would load and then run but would then disappear, Toolbox 4.1 won't load when you use your disc, I'm not sure what I did but I eventualy got the Toolbox 4.1 to load from the disc by finding the application on the disc and running that, it seemed to be hit and miss because I tried several times.

Canon DR-2050C Scanner gets verticle line down image

I have the same issue with mine and there are 2 image sensors on this scanner. 1 in the back that you will see when you open the front that has a meteal shield covering the top half, and one in the fold out front that faces the inside. These are the "glass" sections everyone is refering to. Problem is, they are plexiglass, not glass and mine has a tiny scratch in the lens that is causing the line. This could be your problem. find the lens and use a LED flashlight to inspect your lens for scratches. If its scratched like mine, the entire module has to be replaced to fix it. The canon part number is MH7-7038 and they range from $125-$160 if you replace it yourself. The one in the front is easy to do, but the back one is a little tricky. Hope this helps. E.
