LED GREEN

I am guessing that this is about exposure Green LED on DKS3 (and DKS4) which are very expensive when buying from KIS  :o

DKS3 (and DKS4) uses Green, Blue and Red (lot off RED LED`s  ;)), LED as exposure source instead off the halogen lamp used on the DKS1 and DKS2.

I changed a couple off this Green LED on few DKS3 and they last about 1 year (if the KIS did not change something to last longer ?)  :-/

Thanks for sharing..

Now I learnt a lesson that DKS2 had MSB/LCD life issue and now DKS3 / DKS 4 will have LED light source costy and life issue !  Sigh !

I hope that KIS changed the LED type on the DKS4, but that is the 1W Green LED and should cost maybe 10€ if you find the right one, but unfortunately when buying from KIS (S/A with the diffuser) that price (with some distributor margin and VAT) is multiplied by x25  :-/, so it is not too expensive, but for one 1W LED it is too much  :-/

I found one in local electronic shop (only LED without diffuser off course) for 2€, but it was not stable as original  :o

But at least I had issue only with Green one and not with others  ;)

Hi All,

You can get online with RS Electronics, I am in South Africa. The Green LED is a match just does not come with the diffuser, heat sink, ect..... cost about the equivilant of about 15 Euro's. RS is a UK comapany and do have an online solution and shipping.

1770 is good minilab with good exposure system, but there are some weak points like this Green LED, then flat cable (not expensive) near LCD, transport PCB had some issue with driving the main rack motor and exposure deck and also the feeder rollers are without suspension and they are very sensitive to adjust.

The replenishment pumps are moved to the upper position so the chemistry can not get in contact with them, but I had also some issue with this pumps (Iwaki).

Also it would be good if some owner off this DKS3 machine can share there experience with it.

Dear sirs

I have 2 DKS1710, one is over 4 years old and other is 2 year old, i have the green led problem once on the older machine ans cant recall it was expensive to repair, some euros of course but no ripp off.

Then there is the flat cable on both machine had them made locally for 5 euros, machine stop for an hour because of that.

Had to change rack motor on the older machine.

Thats about it.

(I have done maintainance on the racks, repair them before they start jamming)

I can recommend this machine 100%

Best regards

I agree with jorm. I have a 4 yr. old 1710 and it has performed great. I replaced the transport board for $1,900 and a power supply for $80.00 in the time I have had the machine, including through the warrantee period. My friends with other laser machines have a nightmare replacing thier lasers and balancing the papers is a lot of work we do not have to do. It will never compare to my old optical Fuji machine, but I think it is the best digital machine for the money on the market today.

Hey there Mhonchi,

 

It's still possible to buy but now KIS upgraded the green LED's towards a new type of Lumiled.

For the simple reason that these "old" LED's are not manufactured anymore .......

You need a SMD reworking station to do it properly, you need to solder the small LED unit (really small) onto a aluminium base.

Beside that you need as well a new type of diffuser because the LED is much different as before ....

 

Doeing these actions you'll have an Original green LED like KIS is using for the moment.

 

Note: to be used in the DKS 3 and DKS 4 series

Hey Mhonchi,

 

I understand but to use the new LED's from Lumiled you really need an SMD reworking station.

The LED needs to be assembled on a aluminium mounting, this is possible with a SMD reworking station and a steady hand ;-)

Just like Pskaro told, the use of different LED's will fluctuate to much and don't give a steady production.

 

So .... at the end it's  possible with the right tools needed.

 

Regards,


Wallie
