Tear Downs - Brother DCP-J715W Printer

WARNING: No power should be applied while dismantling the consumer product, appliance, machine, etc and be particularly careful of any big capacitors (e.g., especially in microwave ovens) which could still have a charge (using a insulated handle screwdriver, short out capacitor terminals.

SAFETY FIRST: If you are going to dismantle a consumer product, best to wear gloves, eye protection etc.

This is a Brother DCP-J715W that stopped working (power's up but does not actually print) and was donated for salvage by a friend, rather than going to landfill.

Raising the paper sheet feeder and scanner assembly reveals three screws, which when removed allows the control panel to be lifted out as a single piece.

Removal of the plastic cowling pieces underneath the raised scanner assembly then gives access to a number of other screws, which allows the scanner assembly to be removed.

The printer now has the internal component bays exposed which allows removal of the main circuit board, printer head carriage, inkjet cartridge compartment etc.

With the removal of the main circuit board and other now exposed components, what remains is the "base plate" and part of the paper transport mechanism. While this now looks like some scrap plastic, there are a couple of DC motors, gears, rods, limit switches and a bunch of cable wire harness to be cleaned.

Finally, focussing again on the previously removed paper sheet feeder and scanner assembly, some stepper motors, rods and limit switches await harvesting

The tear down is now complete. The "Salvaged Electronic Parts" Section shows the extent of the "booty".

The "booty" collected:

Two stepper motors, two DC motors, bunch of limit switches.

A large quantity of screws, gears, springs.

A high voltage power supply (for the discharge tube).

A quantity of rods, rollers and high intensity light discharge tube.

Finally, the main PCB. The SMD IC's not useful, but the cable connectors and some of the SMD resistors, capacitors etc useful in the future.
