E-2521 G laser (G-SHG) current exceeded

Recommended Posts

Hello.

I work with minilab Fuji Frontier 355.

When I turned it on, it displays the following error: E-2521 “G laser (G-SHG) current exceeded. Consult your technical representative”.

The technician has only one answer "Laser broken, change the laser”.

But it costs a lot  to replace the laser.

Looking in the forum I found a similar problem “E-2522 Excessive B (B-SHG) laser current detected”.

I logged in using the "secret" password (miya).

I found this datas:

-PD current setting 0,00 to 200.00 “63.19” µA-

-Temp. adjust setting 13.00 to 37.00 “22.70” C°-

I reduced "63.19" to “56.32”.

After that the printer worked all day.

But the day after it displays again signal E-2521 and this appears each new restart.

Reducing the value by a few points the printer starts again, but in this way I will soon set the value zero.

I know the laser is probably dying, but it is really too expensive to replace it, considering the age of the printer (14 years old).

I'm thinking of switching to a dry printer system, but it would be useful for me to work some more time with the Frontier 355.

 

I also wonder: if you just need to change a small value to let the printer work, is the laser really broken, or some sensor has gone crazy?

 

Can someone help me by suggesting a cheap solution?

Thanks in advance.

I can repeat the expressions of your engineer:
"The laser is broken. Replace it."
All your tricks with changing of the values will definitely kill the AOM driver.
And then you will ask here: "how to make a dead AOM driver working again?  It is very expensive to repair it".
Sometimes you have to pay if you want to earn.
Sorry.

I am just afraid to imagine what you will write when you see: "Printer head to be replaced"...
It costs around 4500 EURO and you can meet with this message in a very short time. 

Repair of laser costs 1000 EURO.
Self-cost of each print is higher if to compare with prints made by wet labs... 

So I would think twice before purchasing any dry lab in your financial situation.
