Replacing the scanner lamp
If the lamp inside your scanner does not come on or if it begins to
flicker or dim after some time, the lamp may need to be replaced.
If this is the case, call the Microtek AutoTech fax-back system at
310-297-5101, then listen to the recorded instructions to request a
document on how to replace the scanner lamp.
