IR3300 faded or white down middle

[axyun]

Was there a few weeks ago and toner was not coming on mag roller in middle and therefore image was very light or non existent in middle of page. Took apart developer and emptied out toner and cleaned out unit. Put same toner back in but stirred and shook up good before doing so. Copies were fine then.
Just got call friday that white area is back again toward middle of page. I was thinking of pricing dv unit as opposed to changing mag roller though I am wondering if I shouldn't remove old toner and put fresh toner in first. Frank/ActionPhotocopy

add toner message may not be going on/ check


check your Stirring Rod inside / & Mag Roller
Clean the tip of the blade of the developing assembly

could be a Bias Issue
or poor detection of the level of toner.

Check to make sure that the members on both ends of the drum are in contact.
Otherwise,
light images can result.
Are the block members of the developing assembly in contact with the
photosensitive drum

Check the developing assembly locking lever &
Check to see the surface of the developing cylinder is coated with an even layer of toner.
Otherwise, light images or uneven density can result.

Thanks for your response. There was plenty of toner in developing unit. It was just not coming on the middle of the mag roller. The hopper was more than half full. Frank

If everything is OK change toner.

There has to be a cause for not covering the mag roller in the center, open developer and dump/vacuum out all the toner in the unit, being sure no residual toner is left behind. Reassemble developer, and load a new cartridge of toner into the developer. Clumping would be my guess as to what is occurring in your unit.

Sorry mata, did not read your previous post with the same basic advice...

That is what I suspect either clumping as I did put back the original toner after cleaning and checking unit or mag roller problem though why would it take a month for void to come back. Thanks mata + mrfixit. Will keep you informed. Frank

u need to check stirring rod function inside unit/ it keeps a uniform level of toner /prevents settling

Check your plate bias, its circle in red. Or try another developing assy.

i have seen same issue with damaged rods/fins in other similar units/ just because poster turns and coats mag roller, does not mean the rod/fins are turning inside. that is why clumping and gap takes place.

i agree with u REPLACE~~~~~~~~~~~~~~~~~~~~~

Thanks very much guys. I feel that you have prepared me well for call. Frank

I guess I forgot to mention what was obvious to me, but maybe not so in retrospect. The operation of the internals is easiest to observe when all the toner is removed. Good catch!

As the cylinder life is 480k, if you are far above that number, the 2 good pieces of advice to replace the unit would be echo'd by me as well.

Thanks Guys. Unfortunately for us the machine can actually live longer if parts are still available and properly maintained. But as long as I am alive I will not let the machine defeat me. Frank
