Fuji 330 AoM problem ?

[dexter13]

Hello,

maybe someone can help me with a problem that showed up recently on my Fuji 330.

Simply put it does not pass the densitometer test anymore. First the magenta disappeared in the lower part , then the yellow color (see picture). I also got a single picture with some vertical magenta stripes. Strangely i do not get any error message from the machine.

I assume its form the AoM driver, can anyone confirm this.( my LASER is pretty new only 400 hours old ).

-  the chemistry is new

- recently a bit of magenta showed up in the missing part but it does not pass the densitometer test

- I could remedy the problem for a while by initializing the paper setup: colors where "normal" so i could print some pictures but the densitometer test was still negative

Thanks

Is this problem from all of your magazines? Try with other magazine.

Partially close the gap ( from the light goes out)on the bottom of the laser unit and run the test "paper balance'.

if in the missing (closed )part of paper the surface will be white - you need to repair laser unit.

If the paper wil be same in colour (all surface) - you have a problem with chemistry.

If the image you posted is accurate then you should follow Yustas suggestion. Since the white is not very white it looks like you have a contamination problem inside the laser unit. Block part of the light between the laser unit and the paper or pull the magazine out and put it back in so it will produce a small piece of paper without exposure (the shutter will be closed). If it is nice and white then you definitely have a laser contamination problem. If it still comes out off white then it is a chemistry problem.

well,

today a friend of my managed to test the AOM on another machine and it is OK. I should get it back these day's then I will do the suggested tests. Fingers crossed for the "chemical problem "

Hello,

I made yesterday some tests and the paper is not white(it looks like the posted picture), so my chemicals are not OK. I noticed a very fine white dust on the surface of the processed paper and the filter of the PS2 tank is clogged with some white residue.

(the test can be done easy from the maintenance  "menu nr.5" then "paper feed"; it just cuts a piece of paper and moves it trough the machine).

I will replace the chemicals in the PS1 and PS2 tank, hopefully this will fix the problem.

Do you mean the P2 not the PS2? I have seen this white powdery stuff build up in the P2 tank. You should thoroughly flush the whole P2 system out several times and scrub the tank and filter area. The build up can also cause problems with the heater. The build up in the heater insulates the heat from being transferred to the liquid which causes slower heating and can even cause the overtemp sensor to trigger. If you get an overtemp P2 error, you must remove the hoses from the heater and run a 3/8" diameter brass brush through it to dislodge the buildup.

[dexter13]

yes, its the P2 tank, you are right

Hello,

so I fixed the problem. Replacing the P2 chemical did nothing. Since I had no P1 at hand I decided to stretch it a bit with water ( after some discussions with the local Fuji service guy) and , surprise, the missing colors showed up after the first 0.5l of water. To get the paper white, I replaced half of the P1 tank with water,   . I think the guy who mixed the chemicals ( start up kit) messed up by 2x.

Everything is OK now, density test is working again, also paper conditioning.

Thanks for the help,

Happy New Year for everybody !

boa tarde,

Tive problema com a AOM   ,  o tecnico inverteu os dois cabos dela e pude usar normalmente até chegar a outra nova , ela sia com listas magentas e   foi piorando cada vez mais ,,    nos tivemos direito a um recall  pela propria fabrica , verifique se você não tem direito
