Discarded Epson PIXMA
Optical sensor on paper feed mechanism.
No fancy stepper motors here, just straight, cheap DC brush motor.
Accuracy totally relies on optical sensor feedback to control processor.
Print head carriage also uses optical sensor to detect and correct x axis positioning.
Here's and old Canon USB scanner ready for dismantling.
Compact electronics and single drive mechanism.
Stepper drive is the go with this one.
The (toughened) glass plate is from the Canon scanner above, it's positioned in the mock layout on the frame made using Connect-it pre-cut aluminium (aluminum in US) square tubing and plastic joiners which provide great strength and rigidity when assembled
The print head carriage assembly, which will provide y axis drive, positioned within the print bed support frame to establish layout spacing, glass print bed removed.
Here's a discarded Lexmark abandoned on the roadside with other household items. The manual was also carefully included. This unit actually sprang to life and managed to perform a scan, so why was it abandoned? CLUE: green thingy!
Looks like junior didn't like colouring-in, so hid pencil in printer! Of course clever parents weren't thinking about colouring-in when they wanted to use their printer, and it clearly failed due to "pencil jam". >>> BIN! thank you, good, working parts from this discard, including a working 1602 LCD.
