A k4nf.dll error may be appearing while you’re in the middle of a task that has nothing to do with printers photocopiers or cameras. So why is k4nf.dll appearing? k4nf.dll belongs to Ridoc Document System from Ricoh Company Ltd. Ricoh makes a variety of electronics products including printers photocopiers and cameras.

A better question is why would you let DLL files that are causing troublesome error messages and jeopardizing your machines potential (not to mention putting your security at risk) roam free?

It’s really important to start running an antivirus scan regularly to catch anything malicious. That’s where ZookaWare PC Cleaner comes in. They are the premium name in registry scanning.
