Canon MP560 B200hiba
Üdv A fenti dög B200 hibakóddal jelentkezik be. Felnyitott ajtóval jelzi rendesen nyitva az ajtó. Tesztek is lefutnak. A neten tele van a youtube ahogy összetörik, javíthatatlanság miatt. Van egy gombnyomogatási javítás de nekem nem vált be. Pontosabban belép a szervizmódba ott kiírja idle de onnét nem lehet továbblépdelni bármit nyomogatok. Az ajánlás szerint ekkor 4szer megnyomni a stop gombot majd kikapcsolni és jó. Sajnos nálam ez nem vált be. A GeneralTool sem tesz vele semmit mert ezt a verziót ugyan felismeri de nem tudja elérni az epromot. Tudtok valami okosságot? Ja a fej és a patronok biztosan jók mert azt át tudtam tenni egy másikból. Segítségeteket előre is köszönöm. Laci
CANON Pixma Inkjet MG8120 - error B200
Saw lots of videos on these with error code B200. Cleaning the head seems to solve it many times.
So after I put the cleaned out printhead back in, I did the trick again
where u power it off when the carraige is half way to the left, remove power
andapply power.

This time, it said "processing" on the screen, and the carriage did alot of
extra maneuvers, and looked like it was attempting a cleaning cycle.

At the end, the screen said "cover open", and the carriage slid toward the
left,stopped, and (3) cartridge LED's were flashing slowly, which I was told
meansthose cartriges are low ink. If I closed the cover, the B200 error would
eventually come back.

I asked the customer if he had spare cartridges, and he did, so he bought
them over, we put them in , tried again, and same B200 error.

I told him its likely a print head, and he may try ordering one thru ebay or
something to give that a try. Apparently there are microelectronics inside these
heads? Beats me how they control or regulate ink flow. On the back of the head there are about
50 contact pads, which I guess must be sensors of some kind? He did say he took the head out
at one point, and perhaps ESD may have damaged some sensitive circuitry in
there, and now the head is out of spec.

I thought I saw some russian videos jumpering some of the pads on the head to bypass the code....anyone have any success?

Canon MX 475 nyomtató 5012 hibajel törlése (Megoldva) A készülék 5012 hibakódot ír ki. Tudom törölni, de kis idő után újra bejön és nem működik a készülék. Van esetleg javaslata valakinek, hogy mi okozhatja? A honlapján azt javasolja, hogy vigyem szervizbe. Minden segítséget köszönök!
