@clairely_inexplicable cute!

@gewt please someone answer quickly
He's very dirty

@gewt just asked "how do you wash Christopher Walken?"

@cadey like a split keyboard?

@wewet I had to go off and do an interview, so I haven't gotten back to fixing it

Hmm. Tried to reboot, and it hung again while booting windows.
I went into the BIOS to check the temps, and they were fine.

Then the bios crashed.

Uhhhhhhhh

I was making good progress hacking this printer until my entire system froze, completely. Like, the keyboard lights wouldn't respond. That's some low level shit!

@joshisasoftie nice!

The remaining connectors go into the top half, which I don't want to take apart right now.
But I can make some guesses:
THP (white 2x9 pin) is the thermal print head
J118 (red 2 pin) is the button
J114 (white 5-pin) is the status LED

So, connectors.
JP115 (the blue-two-pin JST connector) is the lid-closed sensor.
JP54 (white 4-pin) is the stepper motor.
JP117 (black 5-pin) is the calibration sensor

@doti heh, how did I miss that?

those are all the major chips. There's nothing on the back.

U? is a BD68610EFV 36v stepper motor driver.

U66 is an LM1117 low-drop-out voltage regulator

U67 is a TI TPS54231 2-A, 28-V Input, Step-Down DC-DC Converter

U136 is an SN74HCT14PWR Hex Schmitt-Trigger Inverter

U135 (!) is a 74HC123 dual retriggable monostable multivibrator with reset.

U8 is a Winbond 25Q64JVSIQ 8-megabyte SPI flash chip.

U9 is a CoreChips SR9700. That's a single-chip USB-to-ethernet driver chip.

U14 is a TI TS3A5017 Dual SP4T Analog Switch
