I was using the built-in TPU but decided to switch to the optional 4" x 5" transparency adapter. Now my documents are not being scanned correctly. What happened?
You must power off the scanner first. Unplug the AC adapter from the scanner and then reconnect it. You should always turn off the scanner when switching between the built-in TPU and the optional 4" x 5" TPU (EU-33) in order for the scanner to correctly recognize which TPU is installed.
