Sorry, if have ever hurt your sentiments.
I answer you as soon as I can. Regarding Ricoh I did not get the printer name.
This printer is just having one chip in black. I did not notice this at the time of 7 pin unsolder. 7 is in air and closed it at 8. As already said when the chip is blocked (by black electric tape) the couter works from motherboard. The buggy thing is that as soon as I remove the tape from black cartridge chip the counter starts from where left in the chip (not motherboard). Kindly tell me what to do so that I do not have to buy a new black cartridge ? Whether black with give toner exhausted.
Thanks and sorry for not answering to you.
