![]() hi,
I've here this printer that is "locked" because Ink Absorber waste ink Counter is full so when I power on it give a sequence of 7 blinking orange LED in sequence with green power ON led. Reading a lot over Internet it seem that is an "use&trash" model so there isn't a way to reset manually this counter and also seems that it is not possible to enter in Service Mode status to reset with Canon Service Tool utility. This is really suck because I cleaned already the printer and bought both new cartridges!!! Working around for a while I finally found out the way to enter Service Mode. - start sequence from printer off - push resume button and keeping it pressed, push ON button. - keeping ON button pressed release resume button so you have: green ON LED on - orange error LED off - press 4 times resume button that give you this sequence LED pattern: 1 press: green ON LED off - orange error LED on 2 press: green ON LED on - orange error LED off 3 press: green ON LED off - orange error LED on 4 press: green ON LED on - orange error LED off Next the 4th press release both resume and on buttons. You will hear print carriage move, power ON led blinking and finally power ON LED solid green on (orange error LED off) If I connect the printer via USB to PC and next start the Canon Service Utility v.5103 released in 2017 (so I think that its compatible with this printer release in July 2016) this one is recognised as screenshot attached but everything I press it give me error006 ![]() I think that the BIOS has a lock / protection that doesn't allow use this software even if printer is recognised. I attach here the original BIOS file that has been to be dumped so to change the Counter Value(%) of INK absorber from 100 (I suppose its 100) to 0. On ASCII code there is some reference on 1EAC00. For further infos I found some examples as this value is written on other Canon printer when with ST you print EEPROM info: Canon iP3000 >>> D=020.1 Ps=001.0 Canon MP460 >>> D=008.0 Ps=000.0 Canon iX5000 >>> D=004.5 I think that this printer has just D (Main) value. |

![]() Update Update Update!!!
Looking better on the mainboard there are 2 memory IC's. One an EEPROM of 2MB where is stored the firmware, this one I've attached on the other post. There is also an other EEPROM (24C08) of just on 1K and in this one are stored all infos and settings. This EEPROM is not erasable so this could be the reason that if its not possibile to complete hardware reset or overwriting it it with Canon Service Tool. Taking it off with programmer even if its still not erasable can be over written. Next to modify and overwritten this EEPROM leaving the other AS IS, printer stopped to give 7 LED error and works properly. |

![]() 24c08 is eraseable - just write 0's or 1's all over it.
but dont - it will contain other stuff like the serial number - dump it for a close look |

![]() it's not protected,
eeproms dont have an "erase" function, you just overwrite them with the new data. so for example, fill the buffer with "FF"'s and then write it to the chip. the 24 series is very old - that's why you cant auto-detect them. |

![]() se dopo aver premuto 4 volte resume tenete premuto di nuovo resume senza
rilasciare il tasto il led arancione lampeggerà, se lo fate lampeggiare 4 volte e rilasciate resume, la stampante stamperà un foglio. Ogni lampeggìo corrisponde ad un comportamento della stampante, ma non sono riuscito a trovare il modo di resettare la stampante. if after pressing resume 4 times you press and hold resume again without release the button the orange LED will flash, if you make it flash 4 times and release the resume, the printer will print a sheet. Each flash corresponds to a behavior of the printer, but I could not find a way to reset the printer.: duh:: D |

![]() Grazie, ma questa eeprom è della stampante nuova? oppure è resettata?
se riprogrammo la eeprom 24c08 della mg2550s ritorna a funzionare? la mia mg2550s è bloccata per inchiostro pieno Thanks, but this eeprom is from the new printer? or is it reset? if we reprogram the eeprom 24c08 of the mg2550s will it work again? my mg2550s is stuck for full ink |

![]() Finalmente ho resettato la mia mg2550s ho semplicemente dissaldato la 24c08 e lo riscritta con 00FF in tutte le locazioni di memoria, lo risaldata e la stampante è tornata
come appena acquistata, ora la posso usare di nuovo, ringrazio questo forum su cui ho capito come procedere. Finally I reset my mg2550s I simply unsoldered 24c08 and rewrote it with 00FF in all memory locations, resolder it and the printer is back as just purchased, now i can use it again, thank this forum i have on understood how to proceed.
