Help 3001 photo curb

[Konstantinos]

Thank you for reading this thread

When I print a photo and this photo is being exported it has an unexpected curb.

I try increase and decrease the Oven temperature, I also try another paper (better quality) but nothing had happened.

I have a Noritsu 3001

Waiting for your ideas, thank you in advance.

In the four years with my 3000 I never solved this problem. With the 3501 no problems at all.

Konsantinos, how is the curled paper bothering you? Became a mess at collector plate after dryer, mixing out client orders....  ???

What brand of paper you are using having curl.?

[Peter Thornton]

You could try printing on 6 inch paper? Slower though.

That kind of curl is normal at the end of a roll. It may just be the paper you are using?

[Konstantinos]

The truth is that this problem didn't start from the begining. I bought this minilab 2 years before and this photo curling started before 6 months.

I know that at the end of each roll there is a kind of curling. At my minilab this curling exists from the beginning of each roll. The first print of every roll has this problem.

The oven temperature is at 50 oC and I have no access of redusing it more. I can adjust the temperature between 50 and 65 oC.

I use Fuji paper mostly (Supreme and DP2).

Moreover I have this problem with every size of paper.

Yesterday I tried something.

I printed 2 photos with some seconds delay between them. I let the first one complete the process and being exported normally.

I export manually the second one before being exported (I open the oven cover). At the last part of the oven. Before being curled and exported.

I observed an important difference between those 2 photos. The percentage of curling in the second photo had been decreased 40% at least compared with the first one.

I thought that some parts of the machine don't work properly.

Thanks for your time, waiting for your ideas

Check the fans and filter in dryer area. It is because of excess heat in the dryer.

Maybe there is a problem with the dryer thermo sensor.

Check the actual dryer temperature with a thermometer to see if it is similar to what the machine says the temperature is.

Also check the last crossover rollers (grey felt rollers) are in good condition, as these help to squeeze the print dry, also check the condition of the white sock rollers on the dryer rack, clean/ replace them as required.

Try turning the temperature down until the prints begin to come out damp, then turn it up a little.

Also, perhaps Fuji have changed their paper. It's not an unusual thing to happen.
