I had a prob­lem with an old Epson Stylus Photo R200 print­er. Des­pite being loaded with paper and fresh genu­ine ink cart­ridges, the unit refused to print. The 2 red warn­ing lights on top were flash­ing altern­ately. After con­sid­er­able googling I dis­covered that this error code is related to the ink cart­ridge clean­ing well. Appar­ently it gets full of ink after a cer­tain num­ber of head clean­ing cycles. As usu­al with cheap inkjet print­ers, the warn­ing is based on a counter, not on the actu­al full­ness of the clean­ing well, and the error can be bypassed by reset­ting the counter in the print­er. The good news is there is a util­ity which will do just that. Although it does­n’t list sup­port, I can con­firm that the util­ity does work fine on Win­dows 7 x64の, so I believe it should work on every ver­sion of win­dows since Win­dows 95!
