Re: Unblocking MP610 head .. this worked...

[boyzo]

Magenta stopped working all of a sudden, after 50 or more refills I could not get it to work with the Clean or intensive clean.
Tips from this forum did not work ie. running a stream of warm water over the head jets did nothing not even hot wet kleenex tissue

What DID work was simply several soaks in a few mm of window cleaner in a saucer (the blue type) the last soak was overnight wetting inlet ports with windex and covering the whole thing with plastic, the next day I dried the head and reinstalled it with all the old refilled tanks and it passed a perfect nozzle test and print dense color areas without starving.

Cool

I would never recommend running "a stream of water over the printhead". Ineffective, plus who wants to risk wetting the PCB ? Use the push-pull, adapted syringe method.
Kleenex is another that would fall into the "not recommended" category because it sheds lint far too easily to make it useful as a printhead cleaner. Use a paper towel for the nozzle area and a coffee filter+alcohol to clean the electrical contact.... think low-lint.

1. Speed the process by heating the Windex to about 140F and combining with the above-mentioned syringe method. I like to limit exposure to Windex to about an hour or so and then flush with distilled water.
2. Use Windex Original w/Ammonia-D only (not dripless)
3. Nothing gained by "covering with plastic"..... may force moisture into the electronics

Glad you got it working.

Well the Magenta blocked again after above efforts.
Tried th windex soak .. partial success Magenta was week.

Tried this
Adapted a syringe with flared end to seal over the Magenta inlet port.
Injected windex gently thru' inlet and also did a withdraw.
This worked and all is fine

Whats going on is thickened ink building up OR Air bubbles in the System, could it be the Ink which happens to be High qualith triple filtered from USA

You might want to read through this thread, especially the conclusions in post #14.

Thanks will do
The head is only ~6mnonths old and the carts refill ~30 times
Running fine since the windex injection
Refills always by the german method
