I have an old Stanley 8500. The round tubes that the guide runs on need replacing. Where can I find these tubes.

If the door is heaver than the original you may to adjust the opening force and the closing force. Check your instructions. The closest gdo I found was a chamberlain 8500. Go online to
Elite Series 8500 Garage Door Openers LiftMaster and see if this the same unit. The instructions can viewed . Good Luck

Anon. Check the attached links,instruction and guides, Good luck

Hi

This is not the problem with the ink supply through the tubing. But your printheads need to be cleaned hence using the HP software which is installed in your system try to clean it and it will solve much of the problem you are facing if not then you have to replace the heads.

Regards

at the handel end it will pull apartthen slide the whats left of the old blade and put new won in its place just do it slowly so you dont forget how it goes

Not sure exactly because I don't own one, but the review seems to indicate you push the blade positioner all the way forward, and push a release to remove the old one out the front, and then push a new own in until it clicks in place. With the blade positioner all the way forward.
But the review said it did not work well.

It sounds to me like it has the wrong scan coils fitted to the replacement tube and there is no fix for that. You will need to fit the correct tube or have the old tube re built.
