Capping station:

As the printhead returns to its position, a square cap known as the capping station rises to support the printhead and forms a seal around it. This creates a semi-airtight seal around all the ink nozzles, preventing the ink from drying in the printhead.
There is a pump and sensor connected to the capping station which helps to move and prime the ink inside the printhead.
How to maintain and clean it:
Maintaining the capping station is simple: just apply a few drops (2-3ml) of moisturizer solution to saturate the pad and leave it for 20 minutes.
Fold a lint-free cloth and gently dab to remove the ink and moisturizer. Be careful not to apply too much pressure, as this could harm the capping station "The head moisturizer is a gentle liquid and safe for the head"
After several dabs, most of the liquid will be absorbed (a small amount will remain, which is acceptable).
Do not let the liquid spill outside the capping station into the printer. Some printer models have important electrical components located under the capping station area and can be damaged by liquid.
For a quick cleaning during the printing day, gently use a cotton swab with a bit of moisturiser or distilled water to clean around the edge of the capping station gasket, removing any ink and dust buildup. Ensure that no fibers or lint are left on the capping station sponge or gasket.
Wiper blade:

The wiper blade in a printer cleans the printhead by wiping off excess ink, dust, and debris. This helps maintain print quality and prevents clogging.
How to maintain it:
Place a few drops of regular cleaning liquid or distilled water onto a clean cotton swab or lint free cloth, and gently wipe it onto the wiper blade. Alternatively, you can gently remove the wiper blade and wash it in a small tub of regular cleaning liquid or distilled water, drying it with a lint-free cloth before putting it back into its place.
