Samsung CLX-3175 Cheap toner solution! - Techwatch Support Forums: Digital & Satellite TV, FTA, Cable, Computers, Mobile Phones, Apple and General Tech Forums

polo-g40 · 18-04-10, 01:32 PM

(My Screenshots and Hex files available openly)
I have been working on chipping 2 Samsung 3175FN's, but when the chips came they had a note to say didnt work on the 3175FN, so had knackered one for nothing taking the required chip off!
so I started playing. :-) I recognised the chip that came off as a 24c64, serial eeprom, easily programmed! What information can these chips hold? What format is it in? Give me a few days and I'll work it out!
I had already workied out how to read and write Ricoh toner-chips. { We bought a massive 3800 off ebay for £21 (Got another for £65 as spare).. It kept saying yellow toner low. Checked out how to read the toner chips (i2c, simples), and did look at them but they only had a date in there to alter (in plain text too!) but that fault turned out to be a blocked pipe. A simple I2c lead and PonyProg2000 taught me how to read them in half an hour}
I tried the same lead and program on the samsung "Chip" chip as the one that came off was a 24c64... It came back with 64k data.
So took a big risk as had another brand new one about. I soldered the 3 wires to the laptop on to the existing chip while in place, and tried to read it with the printer on, AND IT WORKED!
I copied it off into a file then onto a brand-new 24c64, soldered it in the knackered printer, and hey preto! It worked again.! With playing I've managed to set all the page counts and change the mac addresses (pain on same subnet). Just by looking for the hex values of the pagecounts etc. ) I've not wrote down which bits are at which addresses, but I wrote a C# fle comparer to spot diifferences so it will only take seconds to write them again.
---------------------------------------------------------------------------------------------------------------------
So, to chip these printers, I have the best Idea I can come up with for now. (I need some embeded unix development help for the final solution!)
Get the printer, solder on 3 wires to the board to a nice connector that a goes to a 9pin serial eventually.. (Gnd, Serial Clock and serial Data, IE I2c).
Switch printer on, copy the chip. Save the copy.
When the toners get low, fill them up using a nortmal refill pack off ebay, and write the chip contents back to the original copy. (Original page counts, etc)
This is where an easy-connector would help, I'm thinking headphone socket on the printer back...? If I can find help with PIC or embedded unix, I would like to build the programmer into a simple single-button unit that does it instead of a PC...
---------------------------------------------------------------------------------------------------------------------
I be glad of any comments!

Hi, any news on it?

i'm waiting for this printer and for now i'm looking how to reset the toners...

for read/write on the toners chips what i need (hardware)? (a circuit image can be cool)

i hope that i can help you in this but i'm not a very expert for this thing

Sorry for bad english and thanks

EDIT: i think is something like this: http://www.youtube.com/watch?v=zj-HKvIasi0 but here he don't show nothing about hardware

polo-g40 · 05-05-10, 06:26 PM

This is the circuit I based it on. I found this trying to get ricoh toner cartridges to think they were new. (I realised this is pointless as it's done on pagecount apparently) They had a chip on that had pins 1 to 4 grounded.
So I plugged in 5v to where Vcc looks like it is, and I tried combinations of pins 5 and 6 until PonyProg read successfully.
Most 24cxxx's will read, just differing sizes. (LancOS Home Page)

The chip I happened to take off the samsung someone asked me to solder a "chip" chip to happened to be, a 24cxxx, unfortunately damaged in removal. So I tried reading the chipping chip, was easy too, but it seemed write protected to hack the pagecount change. (Apparently later firmwares look for this hack, the seller notes this in a separate ebay listing.).

This chip turned the printer language to chinese everytime it was reset and said the black was empty continuosly, so thought I would vainly try programming a blank 24c to go in its place, and hopefully work out where the language "byte" was and put that onto the "chip" chip and it'd work.

While flaffing about, I ended up trying connecting it to a brand new printer's still installed chip, just to try and hopefully help get the knackered one working, and then happened to try the data lines, and hey-presto, can write or read it while printer is on!!!

So I found the mac address and serial number (1st 16bytes), pagecounts @(0x4af, 4bb, 4c7 & 4d3), etc in the hex off the chip, wrote them back, and both then worked!

I then left the leads soldered, and to a nicely mounted headphone socket, so my mate (special needs colege admin) can re-program it back to 100% toner everytime he fills it up.
The mac and serial number settings mean he's got a dump for each at the moment, but I am working on a quick (c# based) progette for setting things that I find (image counts, installed dates, etc)

Only pain is I hve to switch it off and on in between programs (30 secs programming, 2 mins printer warmup!)

Anyway, be in touch if want photo's and stuff, but you'll work it out once going.
If you can find a 24c64 off ebay to play with 1st, you'll just need to power it with 3.3 to 5v. The data side is all ground-driven, so it's only the chip to power (pin 8), You'll only need SDA,SCL and GND to goto the 9pin

Hope all helps, saving money is big idea in my opinion, but remember it invalidates warrantee (unless you can easily un-solder 3 small leads without trace and havent drilled a hole for the headphone jack)

Off to play with the 2xricoh 3800's (4 at home now) that were £61 for two. They worked with a service code reset. Just need cleaning!

This is a diagram, with the chip removed. You will Leave your chip on, dont worry.
Get the brand-new printer, wire up the ponyprog adapter, read it (as a 24c64)and keep it. It's got serial and mac info in.
When refill toner, just put it back. I can send you a few ponters on setting the black to think it's full (instead of 20% as new).
Regards, and have fun!

Just use the white-wired pin to the rs232's gnd, the black and yellow to SCL and the SDA (not sure which, try both ways, won't harm.)

Just noticed the photo of the board with the chip "box" on it with the wires, it came with their chip, It is for demo purposes only.

Hi,

any news on this fine trick, which will be much better than
those reset-chips, which enforce keeping on the printer?

Programming Eeprom is no problem, a small ATmega device
could do this on the push of a button.

Thanks

Chris

Hi Neal, have been following closely some of your work both here and in other forums. Just wanted to know what eeprom programmer (schematics) you are using to read the 24C64 eeprom. Also my printer has 5% left in the cyan and magenta cartridge, 64% on the yellow and 32% remaining on the black. What hex would I need to change in order to reset to 100%.

I am thinking of removing the eeprom and soldering a socket in place and have a few chips already toner programmed to 100% and just remove and replace when required. I would like the counter and everything to work as OEM.

I really do not like the idea of the reset chips where everytime you switch on and off it loses the settings as my printer is a 3175FW model, the last thing I want to do every time is set the network settings and languages over and over again. Thus I am assuming your programmed eeprom method will not have any side effects mentioned but rather work normally. Any help appreciated. Thanks in advance.

BTW, I am aware a dump from your eeprom would be no good as I have the FW model. This is why I am asking you about where the necessary changes need to be made by PonyProg.

Hi,
I have samsung clx3175fw.
The chip removed in this photo location is not 24c64 in my printer pcb at same location.
And the chip i have on the board does not have 1 to 4 legs ground. I mean if they mislead us with changing the chip name to a fake name instead of writing 24c64 on it.

mashraf24 · 13-11-11, 09:14 AM

My CLX 3175 toner showing empty, I open the front door and found that there are four pins set for each color toner and black toner pins which connect to chip are melt due to burn like electric shock, now the four pins not touching black toner chip and continually showing empty toner.

kindly help in this regard, I like to know the exact name of this component so I may google it.
