This is just the thing for a maker in a hackerspace to try.
Would also be a good public class/demo to show the public:
1. That printer mfr's are evil and there ARE ways around it.
2. For the sake of tinkering, and especially if you have all the tools because you MAKE lots of other things. I...
I heard ad of new epsons, so looked here in hopes of ditching my HPc309a. Other than that I was going to look for printers researched on this forum in craig's list or yard sales.
Pharmacist just posted this: http://www.nifty-stuff.com/forum/viewtopic.php?id=7992 about the new line and possible...
I think my Welch dual stage rotary is fine enough for the vacuum needed, I never got around to completing my diffusion pump.
Somewhere I saved a lead surrounded HV rectifier from an x-ray scare tv, it has about 1/8 inch of lead on outside of envelope. Possibly make a hole near a new target...
This looks like the patterns I get with my c309a problems. Especially the magenta. But an OEM magenta cart was perfect.
I was going to test the tension and viscosity of the oem ink, but in just some tests and nozzle checks, no pictures just some stripe purge patterns. I am at less than half...
No, they are easy to make. This one was described in Make magazine and built by someone more a woodworker than electrician.
Its really easy to generate many 10's of controllable kv at good currents.
With a new set of oem hp564xl cartridges, I would like some advice before I test them.
I was going to drill and insert a syringe, but someone said to blow it out instead. Is this safe? How about airlocks, foam etc.
But if it helps provide answers I'll go ahead in a day or so.
I forgot to...
Hmmn I have a whimshurst influence machine next to me, they are an easy way to develop x-ray potentials. Now I just need to look through my tubes for an old 6bk4 regulator that started the tv x-ray scare.
An update to my c309a problems.
I purchased cyan, magenta, yellow, and photo gray OEM xl carts.
I replaced only the magenta cart, and now it works perfectly with the official HP ink.
This points to the MIS ink being the problem as I had the magenta problem on 3 print heads with the MIS now...
I went to MIS because In the beginning I was researching pro photographer forums to look at their ink solutions (pun intended).
On the Luminous Landscape site, I saw reference to complete gray scale ink sets by MIS (now inksupply.com) and went there. I was planning on buying a cis after trying...
Thanks.
The magenta problem was on two if not three carts. I had also checked the contact to the head strainers many times in the past.
Ok, I'll put in the new one and run the HP quality check at first to see if it purges the magenta and begins working, then run the head clean if not...
I'm back after waiting to spend more on this thing, or switch to Canon for future solution and just use up my pints of MIS ink for pretty graphs rather than pictures, then toss the thing.
I'm looking for some guidance to maximize information to the group and minimize further wallet attacks.
I...
What brand of ink are you using?
After all the fighting I've done with my c309a, It has trouble with magenta.
It will seem to work ok after initial fill, head clean, etc. But it starts banding half way through a small picture, has white streaks sometimes at the beginning, sometimes the...
HP c309a printer. Success lately, don't know how long lived.
I'll post photos and details of my journey soon, but right now, after many weeks, two printheads, old/new carts, refillable carts, mine has been perfect for 2 days, sitting overnight with no color mixing or bleeding.
Windows color...
Interesting, mis inksupply said it was a possibility that a bad seal to the bottom of the cart could introduce air and make a leak. This at the time didn't make sense either. I figured it would leak out, of which I never see any ink arounf the strainer seal, or the air would cause ink...
Hi,
Thanks for the info, I'll double check the plug, maybe by looking for bubbles underwater? (not the hole side of course), They look fine under an eye loupe.
I opened the printer by removing the torx screws as needed, also unplugging the scanner top and setting it aside.
When re-assembling...
