In this video, a repairman has two old Canon printers that a customer wants to have fixed. The repairman spends half of his time playing with the printers and confirms that they won't feed paper so he calls the customer to see if he wants to have the printers "disposed of". When the customer agrees, he spends the remaining time tearing the printers apart without any further attempt at repairing.
I recently took six printers to an authorized Canon repair shop and they quoted a minimum of $250 to repair each one and I agreed to let them recycle them. Maybe they then proceeded to cannibalize them for parts.
