Inkjet Printhead Cleaning Method

[Nifty]

Music Image, thanks for the follow up. Maybe other people with new printers / printheads will read this and check things out.

Happy printing!

When I got my replacement head a few weeks ago, it was filled with something that resembled "3-in-1" oil.

Possibly Glycerine? In a protective wrapper it wouldn't evaporate and would wash out with the first head cleaning the printer does on initial installation.

How bout if only an ammonia instead windex...cause nobody sell windex here ????
and mixed with alcohol.....

Hey guys, heres a bit more follow up on niftys query,

...in this thread the person was suspecting that what was sold as a new printer, had in fact been used or "shop soiled". Down on the last post there is a mention of this "film" on the printhead. Heres an excerpt of the post at the bottom.


-------------------------------------------------------------------------


I also called Best Buy for the heck of it to get their opinion (don't
| worry, I don't take anything they say very seriously), and a HP rep
| that happened to be in the store said that it is definitely abnormal
| to have ink residue on the printhead and ink slots, but that it's
| possible Canon did a quality control check. If they did that,
| depending on how many "checks" the printer or print head went through,
| the unit or at least the printhead gets demoted to "floor model"
| status in my opinion. If they ran one print through it, no problem.
| But if they ran several, then I might take issue. Besides, it's not
| good to have ink in those things while they're not being used.
| Somebody posted that "that's why they're in a sealed bag", which would
| make sense since that might prevent the ink from drying. Yet, still
| doesn't sound like a sound practice.
|
| It will be interesting to hear the opinion from Canon tomorrow
| morning.

Were these little beads slightly magenta (reddish) in color? If so, that is
normal. This is the conditioning fluid I referred to. It is there to prevent
moisture and or other contaminants from damaging the exposed nozzle and
inlets.

Even though the liquid was colorless, when I dabbed a paper towel on the nozzles, it was clear that there was still a very light ink residue that matched the colors used in the head. I was not surprised by this - actually I would have been surprised if Canon didn't completely test each head with "real ink" as part of their Q/C tests. This printer has 6144 individual nozzles, and it is very easy to see how a single nozzle might be defective (a mere 0.016% defect rate).

The only way to find out if there were any manufacturing defects would be to test each print head by generating a series of test patterns in each color. The last step in this test would be to flush out the ink and fill the head with a non-clogging, non-drying fluid (like glycerin).

This is normal for Canon print heads. Of the three most recent printheads that I have taken out of the sealed bags, all had the same fluid. Initial print head cleaning should purge the fluid from the nozzles.

hei i found 2 interesting page today :
Here it is
1. http://homepage.ntlworld.com/wilf.james/cartclen.htm
2. http://www.patentstorm.us/class/510/171-For_lithos:graphic_printing_plate.html

Question :
1. from the first page i wonder if it will work?
2. there a lot of information, maybe someone expert could conclude it for us !

About #2, I would be leary of the chemicals suggested in this cleaning method. Sodium Hypochlorite (common bleach) is not kind to items made of metal. I don't know about the other chemicals mentioned. #1 is similar, but less detailed, than the instructions given by Arthur Entlich who, if you email him at e-printerhelp@mvps.org and ask for his print head cleaning instructions, will send them to you in an email. This is about Epsons but is good info to have. I know that in the UK ammoniated window cleaner is available with a name other than Windex. I imagine that distilled water with about 20% Isopropyl alcohol and just a few drops of household ammonia would work.

Today i found a way to get a pure, clean water.....

first i boil it, then i make a filter....from a strong but thin 70gr paper...
I fold it, so it shaped like a cone then put the cone upside down a glass then pour my boiled water onto it.....
it seems work....
i'll try to make a cleaner from it
which contain :

20 % iso alcohol
1 drop cheap dish wash liquid
80 % my " pure " water
1 drop floor cleaner liquid wich contain 17% HCL

Cause i had some problems on my magenta n yellow nozzle
on my both printer
