what to do with ipf8300 print head?

[mstevensphoto]

just curious, after having to replace my print head myself, I'm left with a head with only 172000m dots through it - about 1/8th of it's supposed life. the yellow channel seems to not be coming through very well, the pattern is there and perfect, just not as dark as the new one (which fixed my problems). is there a market for this thing? is there a point in trying the windex/alcohol clean and saving it? I now have two print heads with new warranty and am hopeful that any further replacements are a ways off. anyone want it cheap?

FWIW, you can check for Goobers...

yeah I thought about sitting it in some windewx, there is zero break in the nozzle check pattern, it's perfect just not dark enough. The thing now is that I got a free R head from canon and bought a left head so I'm not too motivated to pull those out and start messing around with this leftover.

I would just throw it away. The yellow channel is probably already broken. I had to replace 8300 head twice and both times exactly 1/4 of block on nozzle check print was lighter. I think the nozzle check print from canon ipf printers is different to epson nozzle check print, where each single short line belongs to 1 nozzle. While on canon it seems to be from 2 nozzles.

I was told that it is pretty common way of how canon heads deteriorate. Also the infrequently used heads also probably deteriorate faster.

BTW, on second occasion I didn't have replacement head on hand and after few more prints I got various errors, ending with one where the printer will not even start. In the end I had to replace the carriage board as well. So I would advice to replace the head early enough. It could of course have been the other way round - that the board was at fault from beginning, but I would not risk it next time and will always keep spare head at hand.
