Canon Experts - Canon s630 Ink Jet Printer

I had poor colour printing and cleaned the Print Head with hot distilled water (and a dash of vodka as recommended on many sites) and soaked it over night. This improved the printing to virtually 100%.


However running the Nozzle check, which prints out a set matrix boxes, the Blue and “Red” matrix have a few of the box sides are missing, making the box incomplete – not many though.


1. Is there a more drastic method of cleaning the print head to unblock it?


2. Is it possible it to use a syringe to open up the small number of blocked ink jet holes, they are very small holes?

Thanks David

A Canon -like Lexmark and HP are properly known as Bubblejets.
That is because the print head consists ofmany,many fine tubes[finer than a human fair] in each of which there is a heater[would you believe]
On the command from the PC the approriate heater heats up to produce a spot of steam which edjects the ink.
Evewntually the odd heater fails, and then progressivly gets worse.
The only remedy is head replacement.

Thanks for your reply Jack.

Can anyone suggest a remedy to clear these fine tubes that I think are probably blocked, as the printer has been little used, but still prints reasonably well. Thanks David

As explained you cannot actually acess the jets - unless that is you access to a lab.
You did the correct thing with the cleaning with alcohol/water mix.
The next step is to stand the item heads down in a dish with a pad[tissue!] soaked in the mix and leave it overnight, and then try and repeat if required - But I repeat also if a tube/jet is dead then dead it stays

Will give it another go as you suggested Jack.
Thanks David

Isopropanol from the chemists is the best thing to use. Leaves no residue and is apparently the solvent used in Printer Inks anyway. Other wise i believe a new head costs £50-60 but a new printer might be a better bet. Shame as i have a S630 and it's a cracker...

Thanks Paul for your reply. It still gives an excellant print, just trying to get it back to square one again. Will try Isopropanol. David

Managed to get to back some more of the "broken" boxes by soaking the head on a issue as recommended by Paul. Will have to try Isopropanol to see whether I can get the few remaining "broken boxes. Thanks David

The above should read "Managed to get back some more of the broken boxes" etc. David

I had a problem a couple of years ago. Tried everything, including isopropanol. Kept getting satis results but only for a page or so.

A new head was the solution for me, but it cost about £80.

Good luck,

Regards,

Simsy

Thanks Simsy - where did you get the new printer head from - Canon?

Anyone - Are there cheaper places to buy a new Printer Head, than Canon? Thanks David
