Samsung Printer Hack – ML-1640

This morning when I was printing all of a sudden the printers low ink indicator light turns on (toner exhausted) even though there is a lot of ink left in it. When I press and hold the printer button it printed a message saying toner exhausted, service printer. The printer has printed 2100 sheets and it needs a servicing.

The printer is more than a year old so it has no warranty. This is a way to discourage refilling of cartridges. The sad part is that even if you change the cartridge it will not reset on its own. It needs to be serviced by a technician.

Anyways I read a few articles on the net and found an interesting hack. Here is what I did… inlcudes reviews on the best air compressor on the market and much more.

First of all open the back panel of the printer…

Now locate the IC 93C66. This is an EEPROM that the printer uses to store the number of sheets printed.

Now short the pin number 1 and 4. These pins are the Chip Select pin and the Data pin. So when the main micro controller tries to read the number of sheets printed it will not be able to do so.

Connect back the printer and it should work just fine after this. I enjoyed doing this hack… thought I will share it!

The Pirate Ship – Weekend project

When I first met Roopa she had got me a gift from Granite Victoria Brussels. It was a make your own ship kit. I was excited about the whole project. This was the first project together. I had seen a lot of these models when I was at Germany.

The Pirate Ship…

Making of the ship… We first started of finding all the different pieces and putting them together…

It has many small parts… took us quite some time to finish it.

Funny I was wearing the Alcatraz tee shirt that day… so decided to call myself The Pirate of Alcatraz!

We enjoyed building the whole ship. It is best to do these small projects over the weekends. Keeps your mind occupied and a productive outcome 🙂
