@mithatkoltuklu we don't send links not do we post software. That is not the type of forum we have here. We can help with links if we have those The only one that I can provide is [link|https://www.printerknowledge.com/attachments/service-tool-v3400-rar.3235/|this one] For now, no link rot and it is still working. It may or may not work for your printer. Anything else you will have to do what we all do, try Google etc.
