Nice job Carlos,

The thing that stood out to me most about your post is the software side of printer troubleshooting. I work as a technical support analyst for printers and in many instances, the issue is a tray is set to the wrong size for the stock that is inside, which will cause jams. Also overfilling trays can cause jams. Many of these issues can be easily resolved if the users took time to read the solution on the screen. Many printers and models are only rated to work with specific paper stock weights and thickness like 20 lb stock is your standard plain paper for printers versus 90 or 110 lb is considered cardstock and is used for specialty printing like post cards, brochures, etc. These can cause issues also, but a lot of issues are user error before it ever gets to the service level of repair.
