Squeegee error on a 248 is strictly that sensor (reed SW) on corresponding (Front / rear) squeegee cylinder is not seeing a change in state... Either a physical obstruction preventing cylinder from exending fully - OR- if it is extending fully, then

I had this problem once a loooooooong time ago with a 248 that was at my previous place of employment. If I remember correctly, my issue was caused by a set screw on the drive gear that had worked itself loose. My issue was stright forward and quickl

Most likely it is a faulty cable in the e-chain . You can test it in diagnostic: lower the back squeege and manually move back and forth for its entire travel the print carriage while monitoring the sensor output of the squeege. You will see at some

Most probable is encoder feedback failure... check encoder connections.
