IRC3220 prints blacks like crust or bubbles..

[maurimx]

I am having trouble with my IRC3220 again..

We are using a 150gram couche paper.. After a few prints, the black will start to appear like a crust on top of the print, or a feel of bubbles at touch..

We have tried changing the paper type, from glossy,heavy 1,heavy 2, color, plain, bond, ....

the only one that gives us the best results is when we choose plain, but after a while, the same problem appears..

If I choose heavy 1, glossy, or color the paper gets stuck at the fuser unit all wrinkled up like an accordion/paper fan..

Any ideas ?

thanks again

This happens on prints, and colour black only? You need to go into your application settings and change the composition of black. Try reducing the cmyk values. I'm guessing that the composition of "K", is using to heavy coverage of toner for the machine to fuse. Check the colour profiles.

150gram couche paper???

You will have to educate me as to what this kind of paper is, I have not run acrossed it before.

Three factors are common to all fusers, heat energy, pressure, duration. In order to accomodate different types of paper beyond 20# plain bond, two of these factors are adjusted in some fashion. Slow the copier path down to increase duration, and increasing the heat energy in the fuser. We never adjust pressure beyond factory specs. I have seen the effect you are describing in heavy laydowns of color or black. The only thing I can advise is how far into it's life is the fuser? It will start to fail at the outside of it's operating spectrum long before you notice any troubles in it's normal range, like 20# bond.

Moder Coated Paper. or just plain coated paper

thanks all for your replies..

I am going to start to make some tests and see how it goes..

Make sure it's not coated paper for ink jet printers as this will cause the same type of problem, usually all over the page. Like cd said it may be that the paper has a lot of moister in it.

thanks for the education ;-)

Now that I have an idea what kind of paper it is, I can add that I encountered several years ago, a glossy paper on both sides, that when run through the 3200 blistered up like a soda cracker. This paper was tested in other 32's with the same result. I had to inform customer that it was not supported in the copier (after confirmation of Canon), and that there was nothing I could due to accomodate this paper. They wanted to print double sided menus with this stuff.

It was really meant for either ink jet printing or offset press work.

That sounds about right, If I remember right the fuser on those machines seem to be a little on the hot side (yea I know there hot) but hotter than some others.

Try it on another machine.
I would check the fuser out myself.
Whats the % of it?
Or me thinks out of spec on this machine.
Try the biger brother machine irc4580 type.
