Don't make us beg for more details!
@stratman, The MG5750 is not a good printer, because its build quality is less that acceptable as an easy printer to work with, but it has all the bells and whistles which can be a great distraction for newbies.
Its also very flimsy with cheaply made parts, paper jams are a common daily occurrence and the 750/751 cartridges are a nightmare, there so small you have to change them continuously because of constant cleaning cycles and as for refilling, forget it, if you had one you’d probably trash it in anger, best describe as, not worth owning IMO.
It would be an excellent gift to give to someone you disliked...
Staying with MP 750, and looking for QY6-0049
I found that same sellers are present under ebay and Alibaba.
Both claim that defective part must be send back return cost payed by customer... to get refund or replacement in the 7 days following arrival.
@le boff, Yes you may find some of the resellers are on EBay, but you mostly don’t get the same protection, when you don’t purchase from within Alibaba itself.
All of these heads are refurbished so until you actually field test them, there is no way of knowing if they actually work 100%, and if there is a problem, it should so up straight away.
My problem now it to know how to keep working heads in good conditions at home for future use.
I know how to clean heads but I don't know how to protect them untill reuse.
what kind of product to inject into heads ? where to find it ?
The best maintenance for a print head is to print as option as possible, preferable daily, and set the printer to use Quiet mode, it’s a bit slower but it can help to keep the head temperature a little lower during a long print run.
As for storage of a head, just wash thoroughly with running water for 5 minutes, next leave to stand in distilled water for a couple of hours (5 cm deep), then dry, plus shake the head vigorously and finally put about 1 or 2 ml of pharmacists’ solution on the inlets and store in a sealed plastic bag...
