Maintenance and Troubleshooting
This part of the manual describes how to replace the scanner lamp, clean the scanner and deal with
errors. Regular scanner maintenance is essential to ensure optimum performance and a long service
life from your scanner.
Replacing the Lamp
The lamp projects the image onto the scanner screen, and
the procedure for replacing the lamp is described below,
along with some precautions to be observed when handling
the lamp unit. If the lamp burns out, use the procedure
below to replace it.
When the lamp burns out, “LP” appears on the Error/User
Mode display.
CAUTION
Immediately after the lamp burns out, the lamp and the
metal components of the lamp unit are very hot. To
avoid being burned, allow the lamp ample time to cool
down before touching it. The lamp will cool down more
quickly if you leave the scanner switched on for some
minutes with “LP” displayed. After checking that the
lamp and the metal components have cooled down,
proceed with lamp replacement.
1 When the lamp burns out, leave the scanner switched on
for several minutes until the lamp has cooled down.
Note
After waiting at least 5 minutes, check that the lamp
has cooled down and then switch the scanner off.
2 Firmly grip the lamp unit on the right side of the main
unit and slowly pull the lamp unit out.
Note
When you remove the lamp unit, “L5” appears in the
Error/User mode display.
CAUTION
To avoid injury, do not touch the interior of the main
unit after you have removed the lamp unit.
