I think the humble inkjet photo printer is one of the most precise and complex piece of equipment to grace our homes. I decided to "unlid" the Pro 1000 to see how it works when printing a typical photo:

- At the 30 second mark, I believe the printer is checking for paper skew with the built in sensor
- The jet engine sound is actually the vacuum feeding system to keeps the paper perfectly flat while printing
- This is critical as I am using a very thin Japanese Kozo paper (43 gsm) that isn't perfectly flat especially at the edges.
- At the 4:50 mark you can see the end of the paper that left the roller. If there is no vacuum feed system a head strike will occur.
