Removing the top Infrared filter
6. Disconnect the lamp cables.
Warning: The lamp may still be hot.
7. Push the lamp cables through the small holes.
8. Remove the old lamp.
9. Bring the new lamp in place, with the little mark at one end of
the lamp towards the back side of the scanner, facing upwards.
Warning: Do not touch the glass with your bare hands. This would
dramatically shorten the new lamp's lifetime.
10. Re-assemble everything in reverse order.
Warning: Make sure that you remove all dust from inside the scanner
before you place the glass plate back. Clean the Infrared filter with an
appropriate optical cleaning tissue before installing it.
Note: If you want to do the replacement yourself with a minimum of
wasted time, you can order a spare lamp before your scanner lamp needs
replacing. It strongly recommended to have a service engineer recalibrate
the scanner after lamp replacement.
