FO2080

[PASTech]

Hey guys, I have a brand new Fo2080 that a customer has in a kitchen. it has only 4k copies on it and we have had to replace the dev/toner 3 times and the drum once. It continuously pulls toner and eventually has blank copies. Anyone seen anything like this before. This last time that I went in there we pulled the machine and replaced it with a loaner to see if the environment is the problem. Still testing that theory. however the customer showed me the prints. It was working fine and then all of a sudden if printed out dark and black pattern where it looks like half the drum is full black and the other have is black streaks. then shortly after that the pages where almost too light to read.

Like I said, we have replaced drum unit, dev/toner unit already.

In a kitchen? Maybe this machine is on a circuit with microwave, refrigerator, electric oven/stove, electric water heater, or who knows what - check ground to neutral, should be less than .1vac and try to put machine on a different circuit.

If only the manuals actually actual displayed common problems and how to fix them...*sniff*

Re: FO2080

You could just read an HP manual, they're designed with an idiot in mind. Gives you a full rundown of common problems, even if they're already stuff we know.

Re: FO2080

Now you! remember we are technicians we don't know anything, ever, especially at a customers office.

Ok, to be fair there are some customer that really appreciate us....too bad it isn't all

Check the transfer unit in the right door. We had the same thing, started acting up 4-6k.

Re: FO2080

I wonder why that happens on these machines as they are practically the same as the Sharp AL- series machine with most of same parts and you don't see the same thing happening on those. At least not with same frequency. I wonder if there is a TB on this as i just posted about developer pulling and light copies . My customers problem started with a loud high-pitched sound that customer had me listen to on phone. Sounded like corona arcing but loud. Frank/ActionPhotocopy

Old Sharpnet posts for similar AR machines agreed with other posts on Copytechnet regarding side door problems. Will an AL-or similar AR series door fit? Might be worth trying. When the AR168s started having fuser related grinding gear issues, I started putting in AL fuser units since they never seemed to have that problem. Interesting though that most of those AL parts machines were from trade-ins due to similar DV pull problems that are being discussed here. I never did much trouble-shooting on those since they were usually too old to put much time into them.

Thanks for the input Oldrn. Frank

Re: FO2080

I had a customer with a similar issue. The machine was plugged into a battery backup and wasnt getting proper voltage. I recommend checking the power source as mentioned above. if its in a kitchen it could be a variety of things. might work fine until the compressor on the fridge kicks in on it's cycle...hard to say.

"every time i print something my computer restarts!" maybe because you have 14 power hogs plugged into the same outlet, dummy.

Thanks Colgrimes. Machine working now after changing transfer unit and cleaning laser shield. Frank

Re: FO2080

Every time I have found developer pull on these machines to be scortron related. (and yes it does happen on the AL series also.) Just because you've replaced the drum unit doesn't mean you don't have the same issue with a new one. The loud screaching someone mentioned is when the screen grid has fallen onto the drum surface.

Ask customer if they ever noticed a heavy black line down one edge of the paper. That's the first sign that it's about to start pulling developer. Clean scortron at that point and avaoid developer pull.

The more contaminated the environment, the more problems you will have. In my experience machine shops are the worst! Never place one of these machines there.

Re: FO2080

Thanks Draph. I have seen exactly what you are talking about on several occasions. One would think changing the main charge unit would take care of this problem but sometimes I think it is more than that. Some drum units do not fit exactly in machine but can be made to do so and door will still close. You get the line you are referring to at frontside of machine. On the back of the drum unit between the contacts from the MC unit is a thin black plastic column. On some units there is an opening at the top. On others the opening is at middle of column.
If you force the drum unit in without making a cut out of the column you may damage the MC unit which can result in the grid laying on top of drum. Don't know if anything else is different on drum ubit which could cause problems but this is certainly one suspect. Frank
