The Epson XP-640’s front is a bit deceptive because at first glance it doesn’t look like much is going on there, but …
There is a USB port as well as a built-in SD card slot on the front panel. Note the blue tape on the front — there are several pieces around the printer that will need to be removed before you can use it.
When you flip up the control panel, you can press the gray button to open the tray and printing area.
The scanner is just under the lid …
Once you’ve plugged the printer in, you can insert the cartridges (more blue tape and a piece of styrofoam will need to be removed).
A bag is included for the plastic covers that go on the cartridges. You shouldn’t remove them until you are ready to insert them, and when you remove the cartridges you can put those covers back on them for storage or disposal. I know that having to keep up with five different cartridges might seem like a pain, but the beauty of this method is that you can replace only the cartridge that has run out when necessary.
