    Your solution is one I have been trying for sometime. HP told me that this model cannot be opened by anyone--me or HP. Probably not true but will give up until it is unusable and go to Epson.

The scanner glass inside is cloudy


I recommend you do not take off the glass. I have done it and was never able to get rid of the dust, which really shows up on every scan. The fogging has something to do with an optical coating on the underside of the glass. If I knew then what I know now, I would let it be. If the fogging doesn't show up in scans, leave it. If it really does show up, the glass itself is often held down by simple double stick tape. You try to keep the tape intact so you can put it back down. It may be strong enough that the plastic frame on top of it could snap. Do it in as clean (not dusty) environment as possible so dust does not drift down inside the scanner. Never touch the lamp or move the scan mechanism. Again, don't do it unless it's showing up on scan results. Sadly, nobody "fixes" scanners, they are disposable, like coffee pots, even if they cost 300.00.

I want to clean the underside scanning glass of the HP C4180 scanner/printer because when I scann, the top is clean, but the scaned pictures look like they have little specks of dust all over the scanned...


It takes several steps to remove the glass carrier for cleaning, but it's not really difficult. You'll need a T10 Torx screwdriver, eyeglasses cleaner or similar, and a lint-free microfiber cloth.

1) Remove usb and power cables. Flip the front covers open (revealing the cartridge-insertion area). Remove 2 screws from the right-side panel, and remove that panel.

2) Open the photo-paper holder on the left side, depress plastic tabs on its top and bottom so it can swing out 90 degrees, and remove it.

3) Remove 2 screws from the left-side panel, and remove the panel. This exposes the gears of the paper-handling mechanism; take care not to move the gears. Disconnect the three ribbon cables connected the bottom circuit board.

4) Flip up the LCD, exposing a screw. (Note that this one is shorter than all of the others.) Remove the screw. Lift the scanner lid and remove two screws just behind the rear of the glass. Close the cover. Lift the rear of the glass carrier, then slide it back slightly to remove it. Take care not to move the scanner bar that remains in the main body of the machine.

5) Keeping the lid shut, flip the glass carrier over over. Spray cleaner on the glass and wipe; repeat as needed. I use a bright light at a low angle to check for particles on the glass.

To reassemble, just reverse the steps. Finish by cleaning the top of the glass.

How to Clean the inner part of the glass for scanning


Generally you should not have to clean the underside of the glass unless you are in a high dust environment. This would require disassembly of most of the printer itself. The glass is held in by double-sided tape or a bead of glue, so don't try to remove the glass sheet itself.

The easy part is the beginning, removing the scanner cover. Next you will have to locate screws around the outside and start taking panels off. Keep note of the panels and the screws. After the side panels are off, there should be a set of screws around the scanner itself that hold the scanner and plastic casing with the scanner glass. Once those are removed, the scanner glass with its frame should be able to be removed. From there you can use whatever you would like for glass cleaning, make sure it is streak free.

Older scanners make this easier. Most of them are 4-6 screws and the top half pops off and can be easily cleaned. A multifunction isn't so fun in this sense.

Hope this helps!

Dirty glass inside scanner


To clean the glass on the inside you must disassemble the unit so that you have access to the underside of the glass. If you save all your screws and are careful to lay things out in the order you remove the it is easy to put it back together and you do not have to worry about breaking anything.
Once you have access to the underside of the glass I use real windex and newspaper. With the newspaper you get a streak free shine with no lint particles. If there is dust inside the glass there is most likely dust on the scanners optics. Gently clean them the same way. Be gentle when cleaning the scan bar optics. They are not extremely delicate but it will break if you apply too much pressure as it is a long thin piece of glass.
When you put your scanner all back together it will scan as good as new and all the little black specs and streaks will be gone in your scans. I've done this 100+ times and it works every time. If you need help feel free to contact me an I will walk you through it for free.
I hope you found this info detailed enough to fix your scanner yourself, But If you need some help or moral support feel free to E-mail me and I will even call you for free. Make sure to say what you need in your E-mail as I fix a lot of things for people.

There's probably nothing you can do for dust under the glass, but in the Advanced settings for your scanner, there is an option to turn on "Reduce Dust & Scratches", with three different 'strengths'. You may want to try this to see if it helps.
