Incompatible toner - Trying to clean out bad toner from iRc3380

[Guest]

Has anyone ever cleaned out drums with bad toner. I have a client with perfectly good drums however they purchased aftermarket toner from china and (of course) toner is not compatible. Now they are getting inconsistent coverage as the Chinese toner is simply does not have the correct properties to stick to drum.

If I open the slide on the drum I can shake out the bad toner that has entered the toner cavity of the drum units. I was going to then use compressor to blow excess toner away from the surface of the drums after emptying as best I can. Next I was then going to run a few 100 full sheets of c,m,y,k to eventually get the majority of the bad toner through the drums.

Any thoughts suggestions appreciated. All the drums only have approx 7 % life used so it seems a shame to have to toss them. The customer can live with the odd contaminated bit of toner that would most undoubtedly find its way into the odd print.

I agree with what your doing, it should remove the toner just dont put any originals in till the machine stops functioning then add them and do heavy copies. The machine will need a good cleaning afterwards

U HAVE SHAKEN OUT ALL OF THE DEVELOPER
get some new DRUM UNITS NOW


The machine uses a toner projection method in which it deposits toner over the surface of the
photosensitive drum, thus turning the static image into a visible image.
The developer used here is a 2- component developer, composed of non-magnetic toner and carrier.


The drum unit consists of a photosensitive drum, developing cylinder, and a blade.
The developer is composed of toner (mainly of resin and dye) and carrier (iron powder) mixed in a specific ratio.
The friction occurring between toner and carrier causes the toner to become negatively charged and carrier to become positively charged.
The developer adheres to the surface of the developing cylinder by the work of a fixed magnet, and a blade is used to form a uniform layer of developer.
At this time, the areas of the photosensitive drum exposed by the laser beam will have a positive potential in relation to the developing cylinder.
As a result, the toner charged to a more or less identical potential as the developing cylinder will move to and stick to the areas of the photosensitive drum exposed by the laser beam. This phenomenon is referred to as "toner projection," and is used to turn the image on the surface of the photosensitive drum into a visible image.

Is there a hopper on that baby.
Don't forget it , if there is one.
Running PG 5 at 200 then vacuuming the transport seems to be your best bet

u can not replenish the lost developer/ these DRUMS are toast

Vacuum out as much as you can then run full colour double side PG3 test prints until the machine asks for toner, that will be the best way, then obviously fit genuine Canon toners!


I hope you send the customer a big bill for all the grief they give us !!!!!
