Click to Enlarge A Lot More Our software has a lot more features and functions than can be described here. The icon allows you to see the data and also change it. If you need to do 1-to-2 split, or 1-to-4 split, in either byte-mode or word-mode, it is a snap with our software. In, you can select different file formats. Files and Data loads the data from a file into the data buffer which is in the computer. If it does not match, it tells you where and what. Additional Programmer Functions You can a chip against the data in the buffer. That is it! That is all it takes to duplicate a master chip to a blank chip. It also brags about how little time was taken. The reading process puts the data into the computer buffer. Following is a few snap-shots of what our software can do for you. Our software provides lots of useful functions and information without the looks of complexity. If you are lucky enough that your toner chip is still working printingyou can dump the content of the EEPROM before and after printing a page.Programmers Home. Here is an example of a date in hexadecimal values.

Here is a data transfered over USB when I print a page. Thanks to tcpdump, this is very easy see "Bonus 2: snif the USB packets". In the search for evidences, we can capture the USB packet sent by the computer to the printer. I found binary format easier to analyze with xxd. Next I converted the text file into a binary format. The function "printRandomAddress" of the Reset. Since we know how to communicate with the chip, let's read the content of the memory. Here is the output of the program execution on my Arduino.įrom here, we know the device address on the I2C bus is 83 0x53 and the operating clock is anything between 50 kHz and kHz. The directory scanner have a sketch to do this. If you don't know the clock rate and the device address on the I2C bus, you can scan all the possible I2C addresses at different clock rate.

So I just use kHz, see the full discussion. Note: 1MHz seems to be the upper bound of the my Arduino Mega can reach.

In binary, the address is computed like this: 1 0 1 0 A2 A1 A0. If you know the EEPROM model from the circuit analysis, you can read the datasheet and find the clock rate and address like this. If you have absolutly no idea, jump to the section: "Bonus 1: snif the I2C commands" at the end of this page. This is was confirmed by two blogs discussing other model Ricoh printers. But this does not really matter: the analysis procedure is the same. There is plenty of documentation, i like this one from saleae. For example, smartphones use them to connect the touchscreen or the motion sensor to the main processor chip.

IC2 buses are very common on embedded systems. Your computer talks to your printer via a USB link or maybe through wifi. For more information about why manufaturer include those chips, read the about page. We will go step-by-step to understand the problem, analyse the circuit, read the chip memory and write it back so the toner can function again. It took me a while to get everything setup and to have my toner chip reset so i would like to share this process in order to help other to do the same on their printer. There is plenty of information explaining how to refill the toner but little information on how to erase the toner chip.
