Proshivka Chipa Ricoh Sp 111

Der Ricoh Aficio SP 100e besitzt wie die meisten Laserdrucker einen. Daher hab ich mir mit einem STM32 Discovery eine kleine Firmware. I found this thread and ran it through translate as I am also looking to reuse my Ricoh chips on. SP111 SP 111SU SP SF SP 112. SP 112SU SP 112SF SP 110.

As I stated, I cannot find any info on this chip or the new ones (they are black epoxy covered). If you went to the link, you would have seen where they guy on the blog is in the same boat. He has a toner chip that he knows nothing about. He wrote some Arduino code to scan the I2C bus until it finds a device: 'I never used the wire library before and I was surprised by the small number of methods it has. On Wikipedia I read each device on a I2C-Bus has it's own 7-bit address and to communicate with it you have to know this address. So firstly I wrote a function to scan for devices on the bus.

My idea was to try to read from each possible address and to listen for answers. This worked excelently I found the chip at the first try.' Is this not possible to just scan the I2C bus until you find the device?

It seemed to work for this guy. However I can't seem to get it to work with mine and could use some help from people much smarter than me. Yes, I have done this to purchase new toner chips.

You are also correct in that the toner chip comes pre-programmed with a number that the printer deducts from (and writes back to the chip) until it is at zero. Then, no matter how much toner you actually have left, you have to get a new toner (or at least a new toner chip). All of that is documented very well on the link I posted above. I'm not averse to just purchasing new toners, but I thought this would be a fun project to dump the eeprom content from each new toner chip (C, M, Y, K), then have an Arduino uno with four colored buttons that will write that content (based on the button color and matching toner color) to a spent toner chip to 'reset' it. You are also correct in that the toner chip comes pre-programmed with a number that the printer deducts from (and writes back to the chip) until it is at zero. Is it writing back to the chip or is the chip just a serial number that the printer sees a new toner cartridge and then assumes the toner is full and subtracts the usage level internal to the printer and not writing to the chip.

Until you can dump the contents and see if it changes between prints you cannot be sure. All of that is documented very well on the link I posted above. But the link you supplied seems to be for a totally different printer and toner chip so may not be relevant to the one your using. Download atmel usb driver windows 7.
