Printer masters help me please!
The black on my canon i470D stopped working completely after a few weeks of idle. I found some cleaning methods online and happened to have a bottle of 91% isopropyl alcohol at hand. So I put some toilet paper on a disc and soaked them with alcohol, then I took the printhead out and put the nozzle face on the paper, also poured some alcohol inside the black cartridge holder but not the color side of it. Then I moved it to different spots on the paper every half hour or so, both black and color ink did bleed out. After several hours I put the printhead on dry toilet paper and let it sit overnight. Next morning I found some more stain on the paper but I went ahead and installed the printhead.
The black still didn't work, and worse, the color (which was 100% good before this) stoped working too. I did a few clean cycles but still no black at all, and only a few lines of red or blue here and there.
I thought maybe some ink dried and clogged again durying the overnight air dry. so I put some more alcohol on paper in the disc and quickly soak/rinsed the bottom of the printhead on it for a few minutes, some ink came out again. I wiped the printhead dry without touching the nozzles and installed it. Again, nothing printed even after a few clean cycles.
I thought the black ink might just ran out (no way to tell, last cartridge at hand, but it was low), and I probably should not have left the color side of the cartridge holder sitting dry during the first try. So I put the printhead on dry toilet paper this time, poured alcohol inside the printhead on both the color and black sides. The alcohol "sipped" into the paper with the black side almost clean, and some blue/red coming out from the color side. I let it sit for about 2 hours, changing spots now and then, and finally the alcohol floating out seemed kinda clear. So I shaked and wiped the printhead dry, with cotton swab gently wiping out some more ink coming out from the nozzles. Installed and did a clean cycle, then print.
Total blank paper came out.
Hell I thought the color cartridge might ran out too, so I installed a new color cartrige and printed.
Total blank paper came out again.
Any idea what happened to the cursed printhead? Could the alcohol damage it somehow? I have always used the genuine canon cartridges (BCI-24 black or color), maybe I can get some cheaper OEM cartridges just to try to fix the printhead, any good ones out there?
Thanks!
