Hello, we have a DEK 248 just acted up with the squeegee orror. unit powered up initiated and when throght setup a job fine but when we started printing, the back squeegee came down, touched the stencil, stay for about 5 second then came back up with

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

Tony Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because the sl

Have you done Squeegee Heights calibration? (no tools required) Does it complete cal routine without error? Does pressure compensate on next print, with corresponding squeegee, following acknowledgement of pressure error? The readings calibration, ge

Following a pressure error, if continue is pressed, the next print with THE CORRESPONDING squeegee should attempt to compensate by increase or decrease in pressure (as appropriate)... Is it: 1)Not changing at all? 2)Over compensating? 3)Under compens

OK, got a lot of information today doing some testing.. Version number:- 07 SP11 (985 B02) Released Dec 8 2006 I did the tool(less) calibration of the squeegee height, which worked fine, no error. Did a test print, as you can see from the image, t
