printer parts

[charlie_r]

I was recently given an old lexmark X83 printer that had quit working.

The only problem I found with it was the paper wouldn't feed, totally mechanical failure. Everything else worked on it, electronically speaking. The replacement parts were more than the printer was worth, so I tore it apart.

I have several questions about some of the chips on the main board, and the possibility of reuse in other projects. These are only the parts that I would be able to harvest for reuse with my skill level in board making and soldering.

ATMEL ATF 16V8B-15PC (pld) PDIP package

SLK MFP USBC V10-2 (what is it? google came up with nada) SOIC

TI 23C41 3K AHC14 (what is it? again, nothing found on google) SOIC

74AHC08D (Quad 2-input AND gate - NXP) SOIC

XC90105-4FN MOTOROLA part (unknown, still available in online stores, but no datasheet) QFP

XWM8192 WOLFSON MICRO ((8+8) Bit Output 16-bit CIS/CCD AFE/Digitiser) SOIC

39vf020 70-4C-NH (512 Kbit / 1 Mbit / 2 Mbit / 4 Mbit (x8) Multi-Purpose Flash - Silicon Storage Technology, Inc) QFP

MC34063A (DC-DC converter control circuit) SOIC

SD1602H (16x2 LCD module)

If anyone can find out about the unknowns, I would appreciate it.

@ Nigel: would that LCD module work for your tutorials?

Assuming it's a standard one, it should work fine - all those I've ripped out of gear have worked.

As for the rest of the parts, most are special and custom, I think you've already identified the useful bits.

This LCD has 2 COB modules, I am assuming the larger is the LCD controller, and the smaller is the segment driver.

HEX SCHMITT-TRIGGER INVERTERS - Texas Instruments

Didnt find much on the other chips.
