I think the news is good, Dana. I’ve waited 48 hours before I declared victory, but there are no signs of further problems.
Since I last wrote, I woke up to see if the Magenta cart had decided to start flowing. Sadly, things were far worse. The nozzle check was like the one I posted above, but worse! Both PK and M colours were bleeding elsewhere. Worse still, the PK & C carts had drained and the M cart had half-drained. At this point I was on the verge of giving up and buying some OEM carts. But then I read your message:
Do you tap the carts exit valve down on a folded paper towel a few times after filling, to force ink down and air up, before installing into your printer?
Do you let the carts sit for a few minutes after installing into your printer, before beginning to print?
Now I’ve used your carts in various incarnations over the years and have read these instructions many times. But perhaps not carefully enough. I would have said that I followed the spirit of them, if not the letter. To be honest, I was a little confused about this 15 minute wait, and whether it was in or out the printer. Reading again carefully I see that it’s in the printer.
Now I’ve never found the need to do this in the 1410 and R1900 carts that I’ve used. Moreover, I have been a little reluctant to let the freshly installed carts sit in the printer with the head in the ink exchange position for very long. I had a set of refillables from HK drain into the printer and create such a mess in my R2400 that I’ve been gun-shy about doing this. I’ve been in a rush to get the head back over the capping station asap. I have had similar issues on a lesser scale with my ancient 2100, where newly installed carts tended to drip a bit every time they were reinstalled.
But it seems to have done the trick. I have to confess that it’s a little embarrassing that a long time user of your products had to be reminded to read and follow the instructions carefully. Thank you for doing so so patiently and politely.
In my view what this illustrates is that there’s a lot of variability - between printers of essentially the same model (R1900 & R2880) and no doubt between batches of cartridges - if you can just put the carts into some printers and have them work straight away, but need to be more careful and follow the instructions to the letter with others.
In my experience, it’s normal to sometimes have a drop of ink at the exit port of the cartridge, but a good size puddle under the cart would indicate the exit valve didn’t close/seal for whatever reason. This isn’t necessarily a defective cart, but could possibly cause flow issues. On occasion, when I have found a lot of ink under a cart that is stored out of the printer, I generally throw it away and use a new cartridge (but this doesn’t happen often), but with a small drop under a cart, I wipe up the drip and install/use the carts.[/QUOTE]
That magenta cart that was stored out of the printer has continued to leak, and I would say rather more than before. I did clean up around the exit valve and put it in a fresh plastic bag, and there was a bigger pool of ink. This cart may not have been the cause of the problem, but it can’t have helped.
This was a brand new cart that came in my last order. Can it be replaced? I can post it back to you (after washing it out with distilled water) if that would help at all.
