Designjet Z3200 PSU Fan Replacement
« on: January 20, 2021, 01:51:26 pm »

Hello everyone,

I've been a fan of the forum for many years and have finally joined...with my Z3200 currently thoroughly dismantled!

I've been getting a loud noise from the PSU which I'm pretty sure is the fan. So I'm keen to replace the fan itself. I'm no stranger to stripping the machine but have never opened the PSU. I've been using a certain very brilliant website for reference which is great. However I can't find any info online concerning opening the actual PSU itself and what awaits me inside. I was wondering if anybody could give any advice so that I'm fully prepared before I start? Is fan replacement fairly straightforward (he said, hopefully)?

Many thanks in advance,

Brett

Hi Brett - welcome to the forum.

Yes, it is a relatively straight forward process to replace the PSU fan.

You'll need some soldering skills (not much) and ability to disassemble and reassemble correctly.

Refer to this resource

Pretty easy - hardest part will be finding a good fan - others can help with that I think.

Best wishes with your printer repairs,

Mark

My best information from both LPS Computers and personal trial-and-error is that there's something peculiar about those fans, and unless it's a direct OEM replacement the PSU won't even try to turn the fan on.  I replaced one of mine with an aftermarket fan with the exact same specs and had that experience. LPS told me about the issue later.

Thatís really useful information. Many thanks. I havenít opened up the PSU yet so donít know what it looks like in there. Did your fan plug straight in or was there any soldering required?

Thanks

Thanks guys, thatís all very useful. How long can we expect the Nocturnal to last? I wish to hell we could figure out a way got turn these damn things off when not printing. Itís crazy. My Z3100 is only activated when in use and all these years I never had to replace a fan and itís totally silent.

LPS is selling a fully restored Z3200 with inks and heads for 3K. You should buy it Mark :-)

Yes, MASSIVE THANKS EVERYONE!

Unbelievably, since starting this topic my Designjet fan has become whisper quiet again!

So now Iím unsure whether to Ďlet sleeping dogs lieí or to get in there and give it a good clean at the very least?

It was so noisy. However the fan is definitely still operating and it sounds as good as new without any intervention on my part. I find it hard to believe that it was just a piece of trapped dirt. It was very loud and incessant for many days.

Maybe Iíve just got an attention seeking Z3200 which now feels valued again?

They are an amazing machine when fully functioning!

Many thanks again

Brett

Hello GST,
I am about to change my psu-ventilator.

You choose a very silent one but it does not have the blow-power the original had.

I choose one a bit more powerful and bit more noisy, from the same company...

Does everything still works fine with yours?

Works like a champ, more air throughput will not harm, but produce a bit more noise.
Noctua usually delivers the fans with an addition adapter (just a resist) to reduce RPM even further, but I skipped that.
