If you see Scanner errors 20, 22, or 23 on your HP printer, this post will help you fix the issue. Some HP printer users have reported getting these errors when using the scanner. So, let’s find out what exactly these errors are and how to get rid of them.
What is error code 22 on HP scanner?
HP Scanner error code 22 occurs when you try to scan a document or book from your printer. The error code is shown on the printer control panel and prevents you from scanning copies. HP Scanner errors 20 and 23 are also similar to error code 22 and indicate scanner failure.
These error codes are typically caused when an obstruction is inside the scanner lid, the scanner and printer are not connected correctly, or the scanner bar motor assembly is dirty. Besides, if you put additional weight on the scanner gas when printing an open book, it might malfunction and display errors like 22.
If you experience this error, we suggest you restart your scanner and check if you can scan without any issues. If not, proceed with the fixes we have discussed in this post to fix the error.
