Careful with solventinkjet.com

It sounds more like your main board was toast and rather than properly diagnose it, you threw a print head at it which didn't fix it. Now you want to disparage a decent honest vendor in an attempt to get a free fix. Do some research, these printers are designed around the printhead and not vice versa. Another thing that will fry boards is not properly discharging capacitors before fooling around with them. Be a gentleman here, your goal is to get your printer working and I guarantee they can help you but if you keep on they won't and nobody can blame them

This is a real bummer that this happened and I think everyone agrees that it's stressful how quickly money gets thrown around on techs and print heads. That being said I have to second everyone else in that Solventinkjet has always been top notch to work with. We've purchased a number of heads from them and they've steered us in the right direction several times when we were approaching a problem wrong and saved us a lot of time and money so if this is something they screwed up on I'm sure that they will help to make it right. It sounds like they are a small crew though and sometimes it just takes a while and a lot of times it's going to take them a while to get with mutoh and verify everything.

Excuse me??? This printer worked 100 percent before the print head test unfortunately the head was missing nozzles and cleaning didn’t help so of course I ordered a new print head. Placed the new head in and hooked it up just like it was before and boom I got the head heat error. Honestly at this point I’m just worn out. When you have a printer and already behind and have to work your butt off to keep up you expect the head on their website to be correct I even confirmed it with them before purchase. The problem lays that I’m out thousands upon thousands in parts techs and down time. Yes I understand but when you leave them emails also their chat and a voicemail and they still don’t get to you it’s quite frustrating. Because now I have to sit until Monday just to hear back from them. I understand completely mistakes happen we are all human but if your going to advertise a head for this model printer and confirm it’s for that and then they send it to you and you install it because you think it’s the correct head and have this issue pop up where or fries your main board of course I’m going to be upset. I’m not a big shop I’m a one man operation and I think we both know some customers have zero patience’s. Their head was listed at 1800 now they are quoting me 3k. So that would be over 5k I spent this week in parts alone. If I screw up a customers job I can’t just tell them all well deal with it no I make it right and chaulk it up as a loss and make it learning experience.

We did try to replace the cr board and still gave the same error and didn’t fix anything so we put a new main board in today but that’s the furthest we got after he seen the head was the wrong on. I would like to put the old head in that came with the printer just to get ink flowing again but I’m kinda scared to do that
keep in mind, power off. unplug power
WAIT 15 MINUTES to let capacitors bleed down
touch chassis ground first EVERY TIME YOU WALK AWAY, orwear a wrist strap ( are you on carpet, or have hot air heat)


better to observe ALL PRECAUTIONS (believe me, after something is damaged, you always wish you had)

i haven't damaged anything recently, but, i walked up to one of my 3d printers, touched it and the display went blank. i jacked up the humidity & have been touching chassis ground for the last 10 days

be careful and consistent

Your experience here, while understandably frustrating, isn't over yet. You seem hot, and reactive... Intent on slamming this particular vendor. Solventinkjet has a good rep on this forum, give him chance to sort this out and make it right.
Sometimes the wrong that occurred takes some research, and investigation to not only understand where things went sideways, but how to resolve it.

In my past life, I killed my Nikon camera, twice. Just by walking up to it and touching it. It was just sitting on the tripod, but apparently had I had enough static to shock it. After two repair sessions of a few hundred dollars, they got me an anti static mat. Cheaper than the new camera we could have bought after having it fixed twice.
Edit to add, I went through a couple of years of OCD touching everything shockable approaching the camera before the second time, when they finally antied up for the mat. LoL.

no reason to attack him,
many of us have been in that exact same position, (me, MORE THAN ONCE)
changing a head is like surgery, not without it's risks.

if something was damaged by printhead, (or ribbon cables) or whatever, damage would be to the driver/output stage (2sc4131 & 2sa SOMETHING (complimentary pairs)

i am sure he is under a lot of pressure to get back to production AND EVERY ONE OF YOU can understand that

i am not going to steer the thread toward repairing an xpertjet system board, although i would offer any assistance that i could if things went that way

IT COULD EASILY BE ANY OF US

It's unfortunate that this happened. But.. When you decide to repair a printer yourself and the repair goes south, for whatever reason, it's your fault and your problem.
This is the price you have to pay for owning equipment and being in business.
Not when they faulsly advertise a printhead that is supposed to be for you printer and then turns out it’s not at that point it is on them if the sell parts then they should advertise it correctly and confirm with mutoh the parts they are selling are for the correct printers.

Thanks that is exactly the problem. I’m not trying to bash anyone if I don’t have a true reason to. They sold me a print head and confirmed it was for my printer and turns out they were wrong in fact and they admitted it after they talked with mutoh. The problem is if I do a head swap like I did multiple times in Roland printers and Mimaki printers with no issues at all. The problem lays with they advertised something and it was incorrect and in return it cost me thousands of dollars to fix. Yes I am under pressure when you have a lot of customers waiting on their stuff and you have to explain to them what happened and start giving refunds or out sourcing printing. That gives a bad name to my business 100 percent and ruins trust with customers and I don’t like it. People can bash me on here all they want but if they were in the same situation they would do the same thing.

FireFighter, your frustrations are understood, but keep in mind that you also had posted a different problem with American Print Consultants not long ago.
You ranted about their bad service also. You seem to get frustrated easily, we all understand that. But we are all running businesses and I hate to say it but these problems are
part of running a business. Maybe you should find a good local tech instead of seeking suppliers on the internet.

I think SolventInkJet represents themselves a suppliers of printer parts, not as remote repair specialists.

Can you please share the possible reasons for electrical issues after replacing a print head.
Here is 1 possible reason

Spot on. Go back and read that thread and there are 2 more. All complaining about a busted printer and bitching about paying people to fix it. Tech spilled ink all over when changing the head then that same tech says he needs a board after that happens. Doh!
It's pretty stupid for someone to go around ranting and documenting their step by step case of fuckups and then expect a vendor, who can also read the disaster you created, to replace the part you ruined.

For me, it's quite evident, when someone joins just to complain and then creates another thread to complain again about someone else..... when in fact, they messed it up by being a DIYer. There are ways to vent your problems...... and then there are ways to pass blame onto others. This thread is about bashing a very good upstanding member and contributor of this forum with no proof of it. Based upon your carefully chosen words, it's beginning to solve your own dilemma. Go look in a mirror.

Airing out your dirty laundry like this, not once, but twice, spaeks volumes of your character and integrity.

We all make mistakes, but handling yours such as you've displayed is just flat out wrong.

I still dont believe in any way that a wrong part numbered DX7 head had anything to do with frying something. The only possibility is that maybe the new replacement head (unlikely but defective new parts can happen) was defective in some way - just being the wrong part number will not fry anything, a wrong part numbered one just might not work as expected such as solvent ink might melt an aqueous manifold or it it might have gaps or distortion in printing due to encryption. The only way something gets fried replacing a head is either a defective part, ribbon cable damaged and shorted, ink leaked onto the heads board, static damages, or some other part was already fried.
