Printer Teardown:
Functional Schematic
Mechanical Schematic
Electrical Schematic
List of Things Discovered
- Conveyor Belt Like Movement of Scanner Head Underneath Glass Bed
- the gear-tooth rail is part of the plastic form of the printer top and
- the motor that pushes the scanner head is mounted to move with the scanner head
- a surprising amount of electronic board is mounted inside the scanner head assembly that moves with the scanner head
- Conveyor Belt Movement for Ink Cartri
- Locking spring-loaded mechanism for ink cartridges
List of Unanswered Questions from the Dissection
- How much friction will likely cause the plastic-covered electrical connection bands to wear and 'fray' and short out the device?
- The materials seems so light and likely to break easily. Is this an intentional design with planned obsolescence in mind?
