Here are some advices to reset your toner chip with an Arduino.
Some printer toner comes with a small circuit like:
In order to reuse this kind of toner, there are two steps:
- refill the toner with ink (if needed)
- reset the toner chip (or replace it)
There is plenty of information explaining how to refill thetoner but little information on how to erase the toner chip.
This document deals with the second part: how to analyse the chip andreset it.
It took me a while to get everything setup and to have my toner chipreset so i would like to share this process in order to help other todo the same on their printer.
We will go step-by-step to understand the problem, analyse thecircuit, read the chip memory and write it back so the toner canfunction again.
For more information about why manufaturer include those chips, readthe about page.
Your computer talks to your printer via a USB link (or maybe throughwifi). The printer itself communicate with the toner chip via an I2Cor a SPI bus.
So what we will do is to connect our Arduino directly to the tonerchip like this:
IC2 buses are very common on embedded systems. For example,smartphones use them to connect the touchscreen or the motion sensorto the main processor chip. There is plenty of documentation, i likethis one from saleae.
The full specification is avavailable at: http://www.i2c-bus.org/
For your particalar printer, it might be an SPI bus instead of an I2Cbus. But this does not really matter: the analysis procedure is thesame.
The first step is to analyse the circuit. Here you should gather asmuch information as you can:
- Read the part number and search it on the Internet.
- Search if other people have shared information about your printer.
In my case, the chip looked like an EEPROM memory. This is wasconfirmed by two blogs discussing other model Ricoh printers:
I still could not find the exact EERPOM model, but it is of the 24xxxfamily.
Your particular circuit will be different from this one.
If you have absolutly no idea, jump to the section: 'Bonus 1: snif theI2C commands' at the end of this page.
The rest of the tutorial is about how to read and write this EEPROMmemory.
Depending on the board the I2C pins are:
Board | I2C pins |
---|---|
Uno, Ethernet | A4 (SDA), A5 (SCL) |
Mega2560 | 20 (SDA), 21 (SCL) |
Due | 20 (SDA), 21 (SCL) |
Leonardo | 2 (SDA), 3 (SCL) |
Then connect GND and VCC to 3.3V.
To communicate on an I2C bus, we need to know the clock speed and theaddress of the EEPROM.
If you know the EEPROM model from the circuit analysis, you canread the datasheet and find the clock rate and address like this:
For example the datasheet of the component FM24C02Bindicates an operating clock of 1MHz at 3.3V.The datasheet indicates how to calculate the address according to thePIN A0, A1 and A2. In binary, the address is computed like this:
1 0 1 0 A2 A1 A0
.So if the configuration is:
The address is
1 0 1 0 0 1 1
(83).Note: 1MHz seems to be the upper bound of the my Arduino Mega can reach.So I just use 800 kHz, see the full discussion.
If you don't know the clock rate and the device address on the I2Cbus, you can scan all the possible I2C addresses at different clockrate. The directory scanner have a sketch to do this. Here is theoutput of the program execution on my Arduino:
From here, we know the device address on the I2C bus is 83 (0x53) andthe operating clock is anything between 50 kHz and 800 kHz.
Since we know how to communicate with the chip, let's read the contentof the memory. For 24xxx EEPROM, the datasheet for FM24C02B explains how to complete a read operation:
The function 'printRandomAddress' of the Reset.ino sketch implementsthis random read operation. Once the read operation works, you canprint each bytes of the EEPROM one by one and save them in a file.
Next I converted the text file into a binary format. I found binaryformat easier to analyze with xxd:
Here we can see:
- there seems to be a header (0x0 to 0x0f),
- followed by some numbers (0x10 to 0x1f),
- followed by a string (X025M431566)
- followed by some sparse values
This does not make much sense. The next step is to figure out whatthose values are for.
In order to understand the memory layout, we have to think like adetective.
The EEPROM is a simple data storage. The printer might wants to:
- read the toner model (to check compatibility)
- store the number of printed pages and/or the number of printed dot
- mark is as used by a particular printer to prevent second hand market
- mark the date of the first and last usage to make it out of date.
- store toner capacity of page and 'dot' (can be a cound down value).
This is purely speculative at this stage.
In the search for evidences, we can capture the USB packet sent by thecomputer to the printer. Thanks to tcpdump, this is very easy (see'Bonus 2: snif the USB packets').
My particular printer usesPrinter Job Language: PJL.Here is a data transfered over USB when I print a page:
The important piece of information are:
- the DOTCOUNT value
- the TIMESTAMP value
One note about dates: To implement a simple 'out of date' mechanism,year/mount/day is enough. But if the toner needs to warm-up or cooldown hours/minutes/seconds might also required. 2016 converted tohexadecimal is 7E0. Be aware of Unix epoch format. It is well suitedfor this need. Here is an example of a date in hexadecimal values:
32 bits is enough to live until 2038, which certainly exceeded the expectedlife of such product.
To recap, we can expect the following informations in the EEPROMmemory:
- a standard header to verify if the EEPROM is correctly workding
- a part number for model compatibility
- a status/error value (to signal when the toner has caused a problem)
- a 'dot' count number (and/or the number of printed pages)
- a maximum 'dot' capacity (and/or the maximum number of pages to print)
- a last used date field (and/or a first used data field)
Printer Resetter Software
Unfortunatly, I was not able to figure out the memory layout but Iwish you better luck!
If you are lucky enough that your toner chip is still working (printing),you can dump the content of the EEPROM before and after printing apage. This might give you clues about the memory layout.
The process is like this:
Chip Resetter For Hp Cartridges
- read the EEPROM content
- make some changes base on an hypothesis
- write the content into the EEPROM
- try to print a page and restart if this does not work.
In order to speed-up the process, i directly connect my Arduino to thechip inside the printer so i do not need to manipulate the printerduring the experiments.
As for me, i try a couple of random changes without success.Then i had the idea to erase all the memory except the addresses 0x0to 0x0f and it worked!

Another advantage of the binary data: with xxd you can convert thebinary data into a C header file. This C header file can be includedin your program.
Congrats! You have done some work, collected some information and geta better understanding of your toner chip. Let the world knowabout your findings and learn from others!
One way to gain some insight about the memory layout, is to spy thecommunication between the printer and the toner during the printingprocessus.
In order to do so, we can use a logical analyser. This is a simpleequipement that will record the logical state of the wires.
This can be very useful to learn:
- the general properties of the communication (type ofbus, clock speed, device address).
- what memory address the printer read and write
The main open source project to use logical analysers isSigrok. For the list of supported analysersplease refer to supported hardware page.
The following pictures explain the settings:
- attach the wires to the circuit and put back the circuit on thetoner in the printer.
- connect the logical analyzer.
To capture the data transfert, you can use a graphical toollike Pulseview.
You can also use the command line tool calledsigrok-cli as demonstratedbellow:
How to read this: one sequential read of the content of the eeprom,followed by a sequence of write operations: 4 byte at 0x70, 1 byte at0x76. This the printer read all the eeprom, it is difficult to figureout which address hold which information.
Here is an example of USB command sent by the proprietary windowsdriver to the printer (captured with tcpdump when running windowsinside qemu):
