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.

If you are in the market for a black and white laser printer, then the Ricoh SP 210 is one of the best choices in the market for a budget buyer. What makes this monochrome printer a top choice for buyers? Read this review and decide for yourself! Should You Buy The Ricoh SP 210 The Ricoh SP 210 black and white laserjet is one of the cheapest printers to operate. The cost per page for printing is less that 30 paise.

The low toner yield cartridge that comes pre-installed in the printer yields around 1250 prints according to our tests. Print resolution of 1200X600 DPI is supported for crisp prints.

The inbuilt tray can hold 150 sheets of A4 size paper and prints 22 pages per minute. The main selling point for the Ricoh SP 210 however is its price. It costs much lesser than its competitors. Prices are in the range of INR 4000 while competitors are priced much higher. Tones Saver is an option in the printing preferences that allows you to save toner by making the prints lighter. This is a good option to enable when the printed information is not intended for presentations. The prints tend to be on a much lighter that normal prints but information is easily legible.

This mode is only recommended for test prints for personal use. The printer is rated for up to 20,000 prints a month and being a lazer printer its suited for printing everyday or occasional use without having to worry about the ink drying up in an inkjet. These features make this one of the best picks in the budget laser printer category. Check its current price on.
