I have one for the H104s, and H74s... Pretty much the same procedures. I'm presuming this is for changing the print head? If you want the 104s/74s, message me your E-mail and ill send it over. Password mode:
On the printer, in offline state, Hit - cancel, menu, cancel, cancel - It should say "Password?" After that. Then hit -
MENU, UP, Down, Right.
Should work, works for my H2-74s... So I'm presuming its their standard password.
