Lexmark toner chip Ti046b1
« on: April 24, 2016, 03:11:48 PM »
I have a Lexmark CS310dn color Laser printer which has 4 cartridges which I bought about 150$.
Each of them has a chip  Ti046b1 which probably counts the number of copies ( I guess but may be wrong)
When the count is over in one cartridge, the printer stops.
A replacement black cartridge is 100$.

What is the real mechanism for this chip protection ?

Where can I find the datasheet or the pinout of the  Ti046b1 ?  I was not able to find it on the web. It seems that it is a FRAM memory, but I am not sure.

How to reset this printer chip ?

There are some chip available on the web, with the lexmark PCB, but rather expensive (about 25 $) while the chip can be available for only 1$ on  aliexpress. Should a simple replacement of the chip on the board work ?
It is a TSSOP 8 chip, and there nothing else on the board except some decoupling caps.

Thanks for any information on these Ti046b1 chips and chip protection mechanism.

It is a simple EEProm, used to store the count of pages printed and toner fill state. Also has a key that is used to authenticate the cartridge to the printer, and a cartridge serial number.

Try looking in printer refill suppliers for the compatible chips, which are either a programmed chip or a small micro that always reports the cartridge is full.

Thanks, but is it possible to  read and change the values in this eeprom ?

And what is the pinout ?

This is the chip



And from what I have looked I got the following schematics, with the 4 pads  JP1-4 connecting to the printer

Looks like an I2C eeprom from the chip pinout, so...

Thanks for this guess which lead me to try. I have a small I2C address reader that I made a while ago. The correct pinout is in fact

J1 ground
J2 SCL
J3 Vdd
J4 SDA

Then I got the I2C Address : 0x78

What should now be the way to go ?

Grab a non empty cartridge and write it's contents back to the empty one, and see the differences in the data as well. Print a few pages and see how the data changes, which might give enough data to simply reset the count, or make it look full again when refilled. Does the printer work without the chip in, some HP cartridges will give an error code but still print, assuming the chip is misaligned with the reader or it has failed, and then relying instead on the low toner optical path for change messages.

While I can't discount your pinout findings of course, just be aware that there is an unofficial standard pinout for I2C eeproms, so I'd find it unusual to deviate from that, so you might want to just recheck your wiring.

https://proprojects.files.wordpress.com/2014/11/2014-11_i2c_24fc1025_im01.png

For example, Google the images returned from "i2c eeprom pinout".

Anyway, back to the problem in hand!

Can you probe the device in situ with a bus decoder? This can often reveal a lot.

...It might also be worth permanently enabling the Write Protect pin too, so that ithe EEPROM would always report "1 page printed" and not bother you in future. I've never tried it...just a thought.

I suspect that the stored data is encrypted - making it difficult to guess how the printer firmware would respond to various kinds of tinkering. The manufacturers really want you to buy more  consumables for some reason.

@Howardlong : I confirm the pinout that I gave. I have been able to communicate with it with both my arduino based I2C scanner and Bus pirate 3.6 with it.

Now I am trying to dump the eeprom with bus pirate, but I  have never used it before

I can get some reading but I am not really sure of what I am doing.

What is the best way to dump the content of the eeprom ?

Thanks

There are some additional confusions here.

The 0x78 address implies 10 bit addressing as opposed to the more common 7 bit addressing. 0x50-0x57 is the common addres range for eeproms. The schematic you gave even shows the address definition bits and WP pin all tied to how I would expect for an eeprom.

I don't know if Bus Pirate supports 10 bit addressing.

I would take a look at how the printer talks to the device before trying to copy it and match that up with known eeprom protocols. Like pinouts, these are reasonably well standardised so that manufacturers can offer plug in replacements.

I had this value with my arduino reader, and this is what I get with the bus Pirate

In order to verify  what I get with the Bus Pirate,
I tried with a more conventional 24FC1026.

Then the pinout is standard  and I get
I2C>(1)
Searching I2C address space. Found devices at:
0xA0(0x50 W) 0xA1(0x50 R) 0xA2(0x51 W) 0xA3(0x51 R)

Thus the usual address as mentioned by Howardlong

I can then read and write on the chip


I2C>[ 0xa0 0 0 1 3 2 ]
I2C START BIT
WRITE: 0xA0 ACK
WRITE: 0x00 ACK
WRITE: 0x00 ACK
WRITE: 0x01 ACK
WRITE: 0x03 ACK
WRITE: 0x02 ACK
I2C STOP BIT
I2C>[ 0xa0 0 0 ] [ 0xa1 r:3 ]
I2C START BIT
WRITE: 0xA0 ACK
WRITE: 0x00 ACK
WRITE: 0x00 ACK
I2C STOP BIT
I2C START BIT
WRITE: 0xA1 ACK
READ: 0x01  ACK 0x03  ACK 0x02
NACK
I2C STOP BIT
I2C>

But it does not seem that the sequence is the same for the Ti046b1
As If I try the same sequence on  the Ti046b1 , I get

I2C>(1)
Searching I2C address space. Found devices at:
0xF0(0x78 W) 0xF1(0x78 R)


I2C>[ 0xF0 0 0 1 3 2 ]
I2C START BIT
WRITE: 0xF0 ACK
WRITE: 0x00 ACK
WRITE: 0x00 NACK
WRITE: 0x01 NACK
WRITE: 0x03 NACK
WRITE: 0x02 NACK
I2C STOP BIT

[ 0xF0 0 0 ] [ 0xF1 r:3 ]

I2C>[ 0xF0 0 0 ] [ 0xF1 r:3 ]
I2C START BIT
WRITE: 0xF0 ACK
WRITE: 0x00 ACK
WRITE: 0x00 NACK
I2C STOP BIT
I2C START BIT
WRITE: 0xF1 ACK
READ: 0xFF  ACK 0xFF  ACK 0xFF
NACK
I2C STOP BIT

So the behaviour of this chip is not the same as a standard  eeprom.

If anybody has the proper writing/reading sequence, it would be helpful.

10 bit addressing works a little differently to 7 bit addressing, if that is indeed what it's doing. Whatever you're using to talk to the device needs to be 10-bit aware.

Definitely I would sniff out what the printer does to get an idea of what's going on, and look at the I2C specs UM10204 which explain the differences.

Thanks for your comments. I have started to look to 10 bit addressing...

But it is difficult to find reasonable information of  Bus Pirate and I2C 10 bit addressing.

I made an experiment by searching all possible addresses on the black cartridge
searching with Bus Pirate for all 256 in bunches like :
[0xF0 0x00]&[0xF0 0x01]&[0xF0 0x02]&[0xF0 0x03]&[0xF0 0x04]&[0xF0 0x05]&[0xF0 0x06]&[0xF0 0x07]

I got only positive answers for  0 and 1



DELAY 1us
I2C START BIT
WRITE: 0xF0 ACK
WRITE: 0x00 ACK
I2C STOP BIT
DELAY 1us
I2C START BIT
WRITE: 0xF0 ACK
WRITE: 0x01 ACK
I2C STOP BIT
DELAY 1us
I2C START BIT
WRITE: 0xF0 ACK
WRITE: 0x02 NACK
I2C STOP BIT


Then I searched  only for the first 8 addresses  for the other cartridges and found for the possible
second Byte

Black      : 0x00  and 0x01
Cyan      : 0x00  and 0x02
Magenta : 0x00  and 0x03
Yellow     : 0x00  and 0x04

So  this is some progress,  as I understand now how the different cartridges are recognised,
but I am not able to go further. I may need to sniff the I2C port as you recommend, but this will need a setting
that I  cannot do immediately, as I will have to dismount the printer to access the wires.

I'm trying to get information from the chip , but it does not come out . To search using Bascom code :
Code: [Select]
$regfile = "m328pdef.dat"
$crystal = 8000000

Dim Q As Byte , T As Byte , A As Byte , E As Byte , R As Byte
Config Lcd = 16 * 2

 For T = 0 To 128                     
  I2cstart                                           
  Q = R * 2
  I2cwbyte Q                                     
  I2cwbyte T                                     
  E = Q + 1
  I2cstart
  I2cwbyte E                                               
  I2crbyte A , Nack                                     
  I2cstop                                                   
  Locate 1 , 1
  Lcd Q ; " " ; T ; " Read " ; A ; "    "
  If A < 255 Then
  Locate 2 , 1
  Lcd Q ; " " ; T ; " " ; A
  End If
  Wait 2
 Next T
Next R
Loop
End

The answer to all addresses 255. Is there a solution ???

There's no way I'd buy a printer like this.

A bit off topic: are there any printers still around whith reasonably priced/easily refillable cartridges?

Some laser printers have a s/w setting for non-original cartridges, eg Dell.

HP as well, they are refillable, that is why I use them at work. Canon is a brand as well that also has refillable cartridges. The refilled cartridge coasts around 30% of the wholesale price, or around 20% of the retail price. There is a big mark up on cartridges all along the supply chain.

I just ask my refiller first if the cartridges on the printers I am considering are refillable, and this does winnow the list down to a dozen or so to choose from, and then often I look to see if the cartridge is one already in use. Just be aware that often HP and Canon cartridges are exactly the same unit, in a different box with a different part number, and a different price. Lot of Canon printers with me use HP cartridges. Same print quality, same operation and no "non genuine cartridge" message either on the new ones.

If they've got any sense they'll be verifying the writes.

It's weird that they'd use an FRAM and not some write-once memory.  :popcorn:

Did I understand you correctly??? An attempt to read the memory via a separate device ???

The fact that the chip is written in the page counter. As far as I understand it in these chips is:
1. The number of printing on many targeted chip (I found 10K, 20K)
2. The number of printable pages
3. Region kprintera.
4 for color, he must still be responsible for the color.

My reading of the sample controller chips Samsung alas, not what happened. But I realized that chip crypto protection.

no , i turn on the printer and i sniff the initial trasmission that check all chips, and after turn off the printer and repeat for 24 times. the second file is the same procedure with the black cartridge chip removed . i did another test and i attach new file :
senza filo is the 3 initial check without cable off all chips
stamp pagina is the initial check with all chip connected and 2 separate page printed
cartucce mancanti is the recheck without one chip at once.

i made an attempt only with black chip to read the content inside of the chip, but after select the chip address with 0xf0 0x00 , i test to write the address of memory location , but when i read the chip answers always ff when the address is ack

Brother would be another.  :)

Resetting a cartridge is nothing more than moving a gear back to it's start position. And you can refill a genuine cartridge 2- 3x w/ a reset between each refill*.  >:D Makes them the lowest per page cost I'm aware of.  :-+

* Depending on the amount of toner the refill kit contains. Also, replace the fill cap rather than reuse or there's a serious chance it will leak, as they tend to get mangled when removing them (inexpensive & available on eBay and Amazon; new gears too, should you need them).

Hi, I am new to your forum and found it googling for chip TI046B1.
I am also interested in re-writing my lexmark smart chip with a virgin file.
My MX410de uses this chip in the toner and in the imaging drum. The important thing is that I have an original 602HE 10.000 pages new and boxed cartridge.
So I was thinking that if you help me read its virgin file I could re-write it when the time comes. Of course I would also share the file.

Any suggestion would be highly appreciated

Thanks in advance
Michael

i tried to read this chip , and i founded for black cartridge chip that there is just one address that contains data ; all the others contains FF or 00 . I found this with bus pirate scanning step by step all address :  first [0xf1 xx , and i found that the only addresses that answer ACK are f1 00 and f1 01 . Second [0xf1 00 xx and [0xf1 01 xx .... at the end the address that answers all ack and return data different from 00 and FF is [0xf1 0 1 0 0.
i attach the content of this address . After i bought another chip ti046b1 and i tried to read the same address ; the content doesn't match . So i tried to write the content of the original chip to the new , but when i try to write the chip answers NACK .
the procedure to read is [0xf1 0 1 0 0 [ r r r r r r r r r r r
i try to write with [0xf0 0 1 0 0 [ data data

I captured the traffic between the printer and the catridge subsystem using a MiniLogic analyzer. Bus Pirate gives erroneous results.
My first notes:
  • The catridges have 10 bit addresses. First byte 0xF0 (W)/0xF1(R), second by 0x01-0x04
  • There is another FRAM attached to the bus having address 0x05
  • The printer communicates to the bus in cycles. When opening and closing the lid, it starts 5 cycles
  • On Each cycle it polls each catridge by sending 0xF0, 0x0x (x=1-5). If it receives an ACK on the second byte that means the catridge is installed, and sends more bytes. If not it tries one more time before moving to the next address.
  • An ACK on the first byte (0xF0) is always sent by the installed 5th FRAM
  • First 4 cycles looks like identification. 5th one is the actual communication
Attached are the SAELAE Logic Capture, the Decoded CSV output, a simple python script to beautify the results and the beutified results.
The data are from a cs310dn printer, no catridges attached, so the communication takes place only between the printer and the internal FRAM.
More to come soon

#update: The 5th FRAM report a S/N CAHxxxxxxxx and part number 38CB0001. It points to a company named sirtec in HK manufacturing toners for Lexmark. But there is no toner installed!

I can say one thing. chip read and until I got to read and write 1024 bytes open for writing and 1024 closed. In a closed file, there is a number, a model, and many that are not understandable.
While well go into the discharge with a small amount of toner.
I have models 511 and 410. 511 even some with 0 pages went into rewriting.
Under No. 1, there is a toner. Under No. 5 there is a photo drum.
While there are works with the search of the recovery from 0 pages.
Open to HxD.

Hello ,
igrok_by in your picture R5L16B is a memory chip equivalent is FM25L16 (RAMTRON).i have dump for this (my printer is mx310dn).i'm trying to identify a programmer for ti046b1 but can not find any documentation for this chip.

there is no documentation for the chip. I asked many who sell them. But it seems to me that this is not just a memory, but a controller programmed to impersonate itself for memory. Because my attempts to return the blocked chips are unsuccessful. I'm waiting for the listener with China to test my theory.

I can recover a chip that is not blocked.

in romania some devices can be reset, but they must still contain information.of the scheme seems to be a memory but I think it was labeled with a special series.thanks

Opportunity.
But I had a chip on the verge of blocking. I thought that he allowed the lock and counted again. Global changes nebylo. Recorded contents before blocking. But it did not work. I know that one thing is that he is not confused, but a controller. He has 2 addresses for an answer.
The first one is 0.
The second one depends on where it stands. 1 - if this is the bottom with the drum unit and 5 - if there is toner.

Hello,
igrok, where you ordered the chip??for what printer is it??I found that ic's "2850" is a TI controller in the series MSP430FR57XX.

Hello. These chips were bought by our marketer.
The listener came from China. So far as I thought, it's not a memory controller. You need to get a lot of data to write your controller with reset counter. If you do not care to reset the lock of chips.

Hello, friends.
 I did not write for a long time, I was busy trying to understand what kind of animal it was.  :phew: :horse:
I recently offered to share with you.
1 is not just a memory, but a controller or memory that can generate encryption.
2 Yes, yes. Encryption. The algorithm is similar to "AES". This leads to his long attempts at deciphering without knowing the algorithm. Can anyone work with AES, help me understand how this works.
I took off my hat near the development of this chip. This works well. :clap:

wouldnt it be simpler to hack the printer formware to fake the check result?

as far as I know, I was told, I did not check that the printer is updating the encryption algorithm from the chip. Unfortunately, I do not have a printer firmware :-//.

I'm also pretty sure this memory has embedded security. It is probably the case of this lawsuit https://www.eff.org/document/sixth-circuit-opinion

Hello. I see that the information does not appear.  :popcorn:. I want to boast that the "beast" has been trained. The chip fits perfectly into the reset  :-/O. All informatics can be given for a reward. :popcorn:

How?
After a long training =)
There is no documentation for the chip. I found how it works. And now there is a solution that allows me to restart the mx/ms 410/511 chips.
I think that the others work on the same algorithm.

Dear igrok_by, I'm very glad that you have succeeded, But, could you chance, forget how it's done, or break your computer, accidentally format the hard drive. Hope for understanding.
With respect! :)

Chinese friends offer good chips at good prices. True, these chips are clones of the original :). I was surprised when I got five chips with the same number.
