Frontier 570 - Dirty paper

Recommended Posts

Hi friends, how are you?

I have a dirt problem on paper.

Every morning, my first photo revelations on glossy paper become dirty.

When the machine is producing, this does not happen, but if it runs out of production for about 10 minutes,
again the first pictures will be dirty.

I've done all the cleaning of the racks, put all the new chemicals, did not solve.

I will attach a photo of the first sheet of paper condition setup for you to analyze

If you can help me, I'm very grateful.

Happy 2019 !!!

Final rinse/stabilizer. Last chemical step in ra4. Needs frequent dumping and replacement(filters too). Pull racks and clean as completely as possible. Flush out rinse tanks. Reach in and wipe down with paper towels to get rid of slime as best possible. First tank is the worst as replenisher is put in the last tank and reverse cascades(overflows) backwards to the 2nd to last tank which overflows backwards to 3rd to last tank. So net result is the  first stabilizer tank has the oldest/dirtiest solution and it gets hit the hardest with the bleach/fix getting carried over into the first stabilizer tank. Even with good volume the rinse tanks need to be dumped and cleaned frequently.

This problem is most likely caused by Algae growth in the wash tanks, changing the solution only helps for a short while as the Algae starts to grow back again.

You need to kill the Algae by draining the wash tanks and filling the tanks with water and adding household bleach (toilet cleaner) to the water and leave for at least 12 hours. Soak the STB crossovers in household bleach as well.

Then thoroughly rinse the tanks and racks and crossovers and fill the tanks with fresh STB solution.

Also check all the replenisher pumps are operating correctly.

Be careful. You don't want to mix the clorox bleach with the bf solution. I believe when the chlorine mixes with the ammonia it produces chloramine gas which is hazardous. I have seen a strip mall evacuated and hazmat called in when another lab cleaned their bf tanks with clorox.

Friends,

We have not done the cleaning for lack of time,

but something crazy happened rsrsrs ...

We changed brand of glossy paper.

Before, we used kodak paper and now we're with fujifilm.

And it's not messing up the paper ...

Very strange!

No it's normal. Fuji paper does not attract the dirt like Kodak paper does.

Fuji paper is much more slippery so the dirt doesn't stick to it so easily.

Hi,

check with you all, how long do i need to wash the rack?

what solution or chemical do you all use to wash the rack or crossover for clearing those dirty/tar chemical?

Thank!

 

after the exchange of paper brand still did not wash the tanks and racks,

because they stopped coming out dirt on the fujifilm paper.

We only washed the last 3 tanks for the stabilizer.

In the future when doing the cleaning I will post here the results.
