I tried to update a bunch of xp-342 printers and i got this message after firmware sent by wicreset "room not writable" I got about 6 printers stucked of 9 I tied and wasted about 16 firmware key, I also got one xp-245 printer stuck but I can't figure it out once no screen on this one but I presume it's same problem,when i restarted the printers is say recovery mode!!!
