Hi to everyone,
Based on this forum (
https://www.eevblog.com/forum/projects/lexmark-toner-chip-ti046b1/?all#lastPost) i try to analize more deep this chip.
Why deep analize?
I have 3 resetter of Lexmark/Konica Minolta/Dell chip, and all of this resetter tell to some chip are BLOKED, or they can reset only some part (ex: 15%, 23%, 80%) from capacity.
Capacity of chip are write on this chip. I read almost 200 chips in diferit situation, to see if this chip have some change in other place, not only in resetted block, but no diference.
I dump the chip from 00>00 to 19>FF, to check if are some diference, but no. Information from 00_00 to 09_FF are the same with, 10_00 to 19_ff.
I read on mono chip also 0x000 and 0x001. I try also to go on 0x002 and morestep, but no adress found.
Why i want deep analize is becouse, in Mono carytidge if i try to tell in reset the chip have 0 page, the printer tell me to replace the cartridge, becouse have 0 pages remain, and after printer try to block the chip. I read and dump chip before put in printer, and have 100% reseting ( also with resetter i have not only with arduino), and after i put in printer, i try to read and dump the chip again, to check what printer change. The resettwr tel me in some case, can reset maxim 15%, or are block. But...., i reset again with ardui o and rewrite with old information, and after the resetter tell me is new, but only with maxim 15% of capacity, or, are blocked. But NEW.
Can i find some good ideea to analize more deep this to check what change are there.
Many thanks for ideea
