The answer was very simple actually. I just had to remove the cover by pressing the plastic "wings", and found at the bottom of the space thus revealed the two screws I needed to unfasten to remove the top cover and clean the glass.

I found this answer on my own after not having received support from anybody, and that DOES include Canon websites who do not allow you to ask them direct questions. So far for post-sales customer suppor! It really makes you think before buying anything from these peole again....

    Thanks to Bertican. I just translate it into our language.
    Pertama lepaskan cover atau pentutup. Setelah cover atau penutup lepas kamu akan melihat dua buah mur. Lepaskan keduanya. Setelah itu lepas bagian atas scanner dengan cara didorong atau ditarik mendatar seperti kita menarik laci.

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

Sharp IR 2016 platine glass dirty


The cover plate is above the glass white surface of the scanner. If this is the same dirty stains will come out on copies.
The glass must be clean.
By feeding the original documents through the ADF, the scanner lamp is no longer the path to scan, the ADF is responsible for passing the original document over the scanner, while it remains still placed on the side under a thin glass is to a large glass side. This also must be clean, otherwise you will be black lines on each point or spot on the glass.
Good luck ...

Receiver end of faxes shows vertical black line. I changed drum and toner also cleaned glass scanner. I do not have a glass flatbed scanner only an automatic feeder.


The cause of this problem is usually a dirty scanning glass (there might be ink or white out on the glass). Check the glass really closely or the cause could be dirty optics or a bad CCD board. There are mirrors underneath the scanning glass. Dirty optics can cause lines when faxing or copying. If you can not access these mirrors, they would have to cleaned by a technician.

I need to clean the underside of the glass on my Canonscan Lide20


How on earth did the underside of the glass get dirty?

Ok, never mind that... in the end, it's NOT worth it. In the old days, you could have since scanners were as big as printers are today... but now they are definitely NOT designed for the consumer to service. The scanner is designed for accuracy, even if you were to get it all apart, the odds that you maintain the precision and integrity of the bulb, the track on which the bulb moves, etc, are very slim.

Suggestion... How is the printer you have holding up? If it's getting on in age, it may be a wise investment to purchase a dual scanner/printer (as long as you are spending the money).

Hope that helps :)

I want to remove glas of CanoScan LiDE 25 Flatbed Scannerfor cleaning


Why? It shouldn't be dirty behind the glass. If the glass is dirty wipe the glass with a cloth dabbed in methylated spirits.

Sannaer glass is dirty: Cleaning the scanner glass and white reference strip Follow the steps below to clean the scanner glass and reference strip: Remove any loose paper debris that may be present.
  1. Carefully clean the white reference strip on the underside of the scanner cover (or top cover) with a clean, lint-free cloth, moistened lightly with isopropyl alcohol. Clean only the white plastic part on the scanner cover.
  2. For those models that have a scanner glass, clean the scanner glass with a lint-free cloth, moistened lightly with glass cleaner. The HP Officejet K series and HP fax 1220 have a scanner opening instead of a scanner glass. Make sure that no debris is in the scanner opening. Use canned air to gently blow dust and debris from the scanner slot.
  3. Replace all removed components and close the unit.
  4. Plug the power cord back in and turn the unit back on.
  5. Make a copy to verify the lines are not present. If lines are still present and there is nothing visible on either the scanner glass or the reference strip, the unit will require service.
Instructions are on this HP link:

How do I clean the INSIDE glass/platen?


You mean the inside of the scanner glass? (The platten is a part of the print unit),

You'll have to remove the sides and read cover. Unplug the scanner wires and remove the scanner assembly. Separate the document feeder from the scanner bed. Open the covers of the scanner bed (usually there are screws holding it together). Remove the glass and clean it. Reverse the process to reassemble.

Be careful. Canon multipasses are built a little like a Chinese puzzle box. There are little snaps everywhere as well as screws. Watch out you don't force anything and cause the snaps to break.

Cleaning


Unfortunately, cleaning dirt or debris from under the glass requires disassembly of the scanner and must be done by an Authorized Epson Servicer. Please refer to the Epson Customer Care Centers. if its still within the warranty period call epson.
