08.09.2015: Espon WP-450 - Phantom Paper Jam
This might be a bit different but today I had issue with phantom paper jam, only when I printed from Firefox. All files that were on the PC printed fine. So figured there had to be something up some where other than the printer..
So....I had loaded HTC phone software to my computer. This is the only think different from the day prior.
So I deleted the software and the drives through uninstall, but it did not remove the HTC file under C:\Program Files (x86) HTC (file has 6 folders in it) - so, I went to manually delte the HTC folder and could not do so. It still had something running, not could not be deleted.
So, went in and deleted one by one, till I was left with the file that was running: Internet Pass Through Service exe.
Went to task manager to shut down and denied access thinking if I shut it there I could delete it.
So approached it through Services (tab in lower right corner of task manager)
Services opens up, scroll down until you find the Internet Pass Through Service (name might not contain all words, but you will see it)
Right click on it and stop it.
Then go back and delete the file.
Problem solved, printer now works fine.
Hope that helps anyone else with this type of issue.
