I have an MFP M130 series printer that is hooked up wirelessly. Printing and copying work fine. Scanning is the issue. After Scouring the available support options and the forums for any available solutions and pain stakingly working through each solution, (ie disconnect, uninstall, reinstall etc). After implementation of each solution, and the running of Scan Doctor.......the same error keeps coming back TWAIN SCAN ERROR. Has there been any solution presented that actually resolves the issue? Is HP working towards resolving the software error? As there appears to be multiple types of printers experiencing this issue I would like to think that someone is working on a solution for the twain scan error.
