(Case 00341859)
Hello Lori,
The use of any marker on the surface of the ActivBoard is not recommended due to some brands of marker’s ink being difficult to remove, which can interfere with the smooth functioning of the ActivPens at the board and leave remnants of ink on the board, making the image thrown onto the board by a projector unclear.
For further information on the use of dry-erase markers on the ActivBoard, please refer to Article 11024 and Article 10612 from our Promethean Knowledge Base
