CHAPTER 6 –  MAINTAINING YOUR INTERACTIVE WHITEBOARD SYSTEM

TIP
For information on disinfecting your interactive whiteboard, see

Removing Permanent Marker Ink Stains

You can use a high-odor dry-erase marker to remove marks from a permanent 
marker, because dry-erase ink contains solvents that can remove permanent ink. 
Cover the permanent ink with the dry-erase ink, and then wipe with a lint-free soft 
cloth while the ink is still wet. If any trace of the ink remains, spray a lint-free cloth 
with a glass or whiteboard cleaner, and then wipe the area clean.

TIP
When removing permanent marker ink, don’t use low-odor or non-scented 
dry-erase markers, which don’t contain the appropriate solvents.

Cleaning the Pen Tray

If the infrared sensors in the bottom of the pen tray’s recesses become obstructed 
by dirt, the sensors won’t detect when you remove a pen or the eraser. The recessed 
LED indicators won’t illuminate, and the lifted tool won’t work.

To clean a sensor, moisten a cotton swab with a household glass cleaner, such as 
Windex, and then carefully clean the infrared transmitter and receiver.

NOTE
There are no user-serviceable parts inside the pen tray. Only qualified personnel 
should disassemble the pen tray. If dust or a small object prevents you from 
pressing a button, or causes a button to stick, remove the object carefully.
