Hello again,
I've recently purchase a cj500 converted to eco solvent that is in so so shape. I grabbed it at a good price knowing that the work needed would probably include new heads. I know the machine sat for about 2 years but i don't know much more than that. Mechanically the machine appears to be fne as far as going through the motions however the printing is not good. It cuts fine.
Before i pull the trigger on two new heads i'd just like to make sure i've covered my basis and have tried everything to revive the heads. I've done hours of homework on this forum and would like to thank all that have contributed, what a great resource it is. For someone as green as me, this is the only source. On to the problem.........
One head it shooting nealy a full Light Magenta block, yellow block, and only a few lines of the light Cyan. The other head is absent all together. I'm working on this head. Ink cartidges are full, most are brand new. The pump is brand new. I've replaced all the dampers, and primed them by pulling ink until they are half full. I've performed both the medium and powerful head clean. I soaked the heads over night twice by clamping off the pump lines. I made sure drain lines were not clogged. On the non working head, i tried to pull ink through the head out of the capping station using a syringe. Not a drop, and I could hear air leaking. I ordered and installed a new capping station in an attempt to fix the air leak. Still not a drop and I still hear air.
At this point i declared the head shot. I figured the seal in the capping station must be weaker than the seal in the syringe and the air has to come from somewhere when i pull since the head is clogged. So I thought for the heck of it i would try to gently push some solvent through the manifold into the head. I know this is not advised but I dont have much hope for this head. Suprisingly if flowed through without much effort.
So my question is, does it make sense that if a head is 100% clogged that liquid would pass through it from the manifold. Yet it won't charge enough to print one single dot, or am I missing some other air leak somewhere? Or perhaps it has something to do with the circuits of the head?
Any more ideas, or is it just time to order up some new heads?
