2045e with toner blotches

[mrwho]

Hello there, boys and girls.

I've got a 2045e machine wich sometimes drops some toner blotches on the copies. I've already searched through this forum and found some thread with a couple of hints on how to hunt this particular problem, but I couldn't find anything appearing to be out of place that could be causing this.

To make things worse, the machine only does it sporadicaly and many were the times I left here thinking the machine was alright and having the customer calling back angry telling the machine is a POS.

Please, can someone point me in the right direction?

One area to pay attention to for this particular problem is the tranfer unit. Whan the case starts to get full it can intermittantly drop toner onto the copies. Empty the case and vac the area around the rear of the reg roller real good. This may help.

Another favourite is the dev unit seal that sits on top of the mag roller, if that gets damaged it causes copy quality issues.

Well, so far my suspicions fall on the fixing unit. There are two reasons why I say this:

a) Sometimes (but not always) the blotches show on the exact same spot where the stripper pawls are;

b) The biggest blotches do not appear to be pressed by the rollers (they have that 3D feeling when you look at them and are not flat).

Still experimenting....

Just replaced the stripper pawls - and the new ones look different than the ones on the machine. They are wider whereas the previous ones were thin - somewhat like comparing a duck's bill against a chicken's beak.

Something else that caught my attention was the fusing cleaning roller - it was chock full with toner. I find it odd, since the roller is projected to last 150k prints, but it was replaced just 65k ago - could the machine be overtoning? It doesn't show any other sign of that. I just removed the roller, since I believe it must be doing more harm than good in that condition. Anyone running these machines without the fusing cleaning roller?

You hit the nail on the head.
Remove the cleaning roller out of the Fuser, runs well with out one in it. Causes nothing but trouble. Waste toner unit also need a good clean inside and out.

Good luck

Thanks for the tip - let's see how it runs without the roller. The few tests I made after removing it still had a couple of cases with blotches on them. We'll see how the machine performs tomorrow.

If that isn't it, I don't know where else to look for the solution - I've even took out the units and looked at the machine's chassis to see if toner was building up somewhere.

Those cleaning rollers in the fuser are there for a reason, I would not recomend using the machine without one. They do get dirty fairly quickly but not so much as to cause the fault you described unless of course it hasn't been cleaned or replaced- as in your case. Yes the strippers have been modified. I would leave the cleaning roller in place and clean it every service call- itonly takes 5 minutes.A clean machine is a happy machine

How do you clean it? Some kind of solvent?

[TonerMunkeh]

Nah, just replce it. AE04 2084.

I use alcohol and a kitchen scourer- the green nylon type or if it's really dirty- a scraper

Look at the fuser closely also. Especially the entrance and exit gates.
Toner can build up (looks like little droplets) on the edges. If machine is
used lightly these droplets will build up like a litte bump. Then someone comes
up and runs a big job and the droplets warm up more than usual and
start leaving mark and drops on copies. On low use copiers those
droplets can\build up high enough to cause jamming.
Pop them off if you can or scrape them off if you have to.

Once you see them you'll wonder why you missed them before now
I know I did.

I had some of my Guys pulling the cleaning roller because they were not in PM kit, and it caused buildup on thermistors. How is your toner consumption? Is it running rich.

2045e toner blotches

If your blotches are what i am thinking i may have a solution for you. The ones i have dealt with almost look as if you dropped toner from about 5" off the page and it almost splashes like a droplet of water would. The issue is within the drum unit. Vac it all out and pay close attention to the mylar opposite the drum blade. It gets formed downward and allows toner to fall out of the waste area and onto the page and drum. I use a spring hook and run it under the mylar re-forming it back to its original state. If that fails you can actually just replace the mylar. Good luck

You can clean the older "metal" style (ae042029) as above, but the newer style (ae042084) I would not even try.
