Clean scanner glass - HP LaserJet M5035 MFP Printer

I don't know how the CANON DR 1210-C is assembled but I had an Artec and unscrewing it I could take off the glass.

Hi ,

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 .

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 ...

Solution three: Clean the automatic document feeder (ADF) Use the following steps to clean the automatic document feeder. Step one: Clean the ADF rollers and separator pad

The 3170 has a screw in each of the two slots where the lid inserts into the scanner. Remove the lid, remove these screws, and then the top portion of the scanner with the glass slides forward and off. Mine was stiff getting it off, but with some slight twisting and a bit of force it came off. You can then clean the glass.

Cleaning the glass is rather simple. Take the 2 screws under the cover out. Now gently lift the top part of the scanner (some force may be needed). Then the scanner is in 2 parts and the glass can be cleaned inside and outside with a wet wipe glass cleaning pad. Dry the glass with a towel and inspect the glass with a lamp, that no cleanser remains are left. Now install the scanner in reverse order.

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.
