Re: nozzle check
2015-08-16 by brian_downunda@...
These carts-on-head printers will do a head cleaning cycle at various times - when a cart is removed and reinserted, when an ARC chip resets (which is why removing them all refilling and resetting them all at the same time, if you have a resetter, is a less wasteful approach), and when the printer determines through some algorithm that it's time and the printer needs a head clean.
If the gaps in the nozzle check occur after one of these printer-scheduled cleans, then .... I've had a printer like this (R2400) and never solved the problem. I came to the view that there was an incompatibility between that printer and refillables. I think that air was getting in during a head clean, as not every gap in a nozzle is a clog, especially if the position of the gap moves after each head clean. I tried a range of solutions and refillables with this printer, but nothing worked.
It's not a common experience from what I can tell, but around that time I did see one other similar report from someone else, using a different printer and as far as I can tell (since they all come from China) another brand of refillables. I am also aware of another 1430 user who quite recently has struggled to get refillables to work with an R1430. He finally seems to have had success with "capsules" from IJM after trying two printers and quite a few brands of refillables.
I had to sound negative and defeatist, but that was my experience.
