Problematic Print head?

[scouseman]

Hi Guys,

I have been have a few problems with the print quality of my printer recently, it is a MG6250, I am using original cartridges and syringing the ink into them.
I have been using cheap black dye ink in both black cartridges for some time and up until now it has been fine up until now, but for the last couple of weeks the prints have been very streaky.
For the colour ink I have been using hobi colours ink, which is meant to be good.
I have included a a copy of my head printout
As you can see, the pig blk has got a few gaps, no amount of cleaning it clearing it.
The dye black in completely blank.
The top blue is 2 shades.

Any help would be most appreciated.
I look forward to becoming an active member of your forums.

The upper half of the regular cyan stripe is lighter than the lower half. This is a symptom of electronic print head failure, and only a new print head might bring the printer back to good working order. There is however a risk that a failed print head can damage the logic board in the printer, and a logic board that has been damaged this way can ruin a new print head, so replacing the print head is a gamble, and I cannot tell your chances of success.

Hi scouseman and welcome, unfortunately when you decided to seek help it was a little bit too late to save the print head in your printer.

The pigment black was fine and would have cleaned up but the cyan nozzles look to have an electrical problem, and your BK black is totally burned out and is unlikely to come back no matter what you do with it. [External soaking]

When you have poor output on a Canon printer it is always wise to stop all printing immediately and investigate that issue and fix it first before you resume any further print work, the only exception to this rule is the use of nozzles checks.

The most likely cause of the damage in this case is ink starvation to the print head and when left unnoticed for any length of time that is usually what causes the head to over head and burn out.

I would recommend you look again at your refilling procedure and or change the cartridges that your using, the printer takes 525/526 opaque carts which can be changed for 520/521 OEM carts which can make refilling much easier.

It only take a moment to switch the chips over to make the carts acceptable to your printer, it’s also a good idea to use a quality chip resetter in your refilling technique which will then give you much better control and help protect your print head in future, sorry for the bad new..

Thanks guys for your responses, yes Hat, your are probably right it probably would of been ink starvation.
Now I have the ominous task of trying to find a replacement, having read several threads on this forum that looks as though it could be easier said than done.
Can anyone recommend a decent replacement, requirements, cheap running costs, decent print quality, budget no more than £150.
Cheers

Again you’ve hit another impasse, you should try your best to get a new head for your current printer rather than seeking a new replacement printer, that’s easy for me to say, because a new printer is usually cheaper that a new head.

Stick to what you have if you can because the newer printers are not as good a combination for refilling, cheaper they may be but they’ll get you when you need new carts, most new Canon printer are all AIO’s, print scan copy types.

If you go for just a printer then the Canon iP7250 is cheap and cheerful and wont break the bank, it has all the bells and whistles too and can work great if you get good refillable carts and inks for it..

I had the same symptoms with my trusted IP4300. After a few months it stopped working with infamous VH monitor error [B200] RIP

Sad it happened not only on the nozzles with "cheap black dye", but also with the cyan, filled with a "meant to be good".

As said by @The Hat, refilling is more than ink, it is also the cartridge ink flow (refill before the sponge is empty to avoid foam) and a good working purge system.

Alas, an IP7250 does not replace all the functions of your MG6250.
If you want to keep the printer as a scanner (and evt B/W prints) you should mask the electric connections on the printhead for the cyan and photo black nozzles to avoid the B200 error.

By the way,it can happens also with expensive ink, dye or not.

I used only oem carts and at a later stage refilled the empty OEM carts with InkTek inks.

All started with a slightly clogged text black, and while fiddling trying to fix the black,it completely disappeared and the upper half of the regular cyan stripe randomly started to be lighter than the lower half.

If it can help I had a temporary success in getting back the black, remove BK cartridge,put 4 or five drops of BK ink on the printhead inlet until is full (please refer to this thread for further information http://www.printerknowledge.com/thr...g-clogged-head-or-what.9265/page-5#post-73962), reinsert the cartridge and cross your fingers.

If any colour in a print head is suffering from ink starvation the only certain cure for that problem is a complete purge of that particular cartridge, many times if necessary, you do lose a little ink each time you purge that is all.

Ink starvation is a condition that can be caused by refilling a cartridge too many times but mostly incorrectly, i.e. in other words using a badly maintained cartridge, another is waiting till a cartridge is completely empty before refilling, you save nothing doing that.

The important thing here is to re-examine the way you use a refilled cartridge and of course your own refilling procedures, always refill on low ink warning and never wait till empty, this condition if ignored or left unnoticed can and will kill your print head.

Always remember that prevention is a far better cure than the price of a new head, and if you notice this happing to you then STOP printing immediately and seek help or take the necessary steps to resolve the issue yourself..
