The parameters for Epson transistors

The parameter values between the base-to-emitter and base-collector should be around 700-800 ohms.

Addition to the article "Epson doesn't recognise cartridges".

theoretically it is posible to connect the two parallel transistor (TT3034 and TT3043) and get one dual transistor (A2098 and S6082), but problematic to solder them. They will not work steadily because it is necessary accurately select the characteristics of transistors. In practice, dual transistors don't work for a long time.
