# Leica BLK360 ## The scan button is greyed out Ensure that the scanner is still connected Wi-Fi. You may also need to reset the Leica BLK360 by turning it off by pressing and holding its power button until it shuts off. Turn it back on and try connecting again. *** ## Project keeps crashing when transferring files on the iPad In some cases, scan data can be corrupted, you may isolate this by trying to [manually transferring](https://ms-kb.msd.unimelb.edu.au/next-lab/guides/leica-blk-360/scanning#manually-transferring-scans) scan files one at a time until you have isolated the problematic file. The iPad can sometimes not handle large projects well either, if you think this is the case, try a new project. You can also use the desktop version on the processing laptop to handle larger datasets. *** ## Scanner Disconnecting Turn off the scanner and close the Cyclone app and retry the connection from scratch.\ Reasons for why this may happen is that you are too far from the scanner or there is too much signal interference or obstruction between the iPad and scanner. There may be instances where the iPad cannot be reasonably used. The alternative is to use Push-Button scanning - set the power putting through the app with appropriate delay. Transfer to iPad manually and regularly to check your scanning progress. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
