Conclusion
If your printer is working as well as it used to, then the problem was caused by a clog that needed manual cleaning.
However, if your printer is not working right after letting the parts dry for a little longer, then it is likely the printhead has other problems or was damaged when it was cleaned.
If your printer is working correctly, it was just caused by a clog. Printers with persistent issues have a deeper issue and should be replaced as a complete unit.
