It's still the flaking one. But It's bad. It's missing chunks from

get that today, I'll just order one.
The main
problem I'm having is that every page jams right
before it
enters the fuser. ?Does this sound like the fuser or
some of the
rollers?
Have you replaced the fuser yet, or is it still the flaking one? Is the paper actually jamming, or is it just stopping,
and the printer reports a jam?
When I open the printer, the page is slightly mangled, so I think it's
a jam. I can also hear the paper crinkling right before it reports
the jam. It's also pinched on a roller at the top of the page before
the fuser. But only maybe 1/4" is under the roller. It gives me a
little resistance when I pull the page out. The error is 13.5 and it
tells me to check the back paper tray.
There are various sensors in the paper path, and if the
paper takes too long to get from one point to another (or if there's toner in the
sensor optos), the printer simply assumes that it's jammed and stops trying. Another
thing that really confuses the heck out if the printer is if the paper size is set wrong,
or if one of the flags on the tray has broken off. The paper tray contains little levers
that change flags on the side or back of the tray (depending on model). When you set the
guides in the tray, it changes the flags on the side - this tells the printer what size
paper is loaded. If one or more of the flags is broken, or the switches are faulty, the
the printer thinks the tray contains another size of paper than it really does. This can
also lead to "paper isn't where I think it should be, giving
?up" problems. The test page should tell you what size paper the machine _thinks_ it
has.
I can't print a test page yet. ;-) Well, sort of. I can read the
jammed page that I pull out.
I'll look up the 4100 service manual and see how
it's set up, it's been a while since I've worked on one (most of my customers
are on different models), so my memory is a little rusty.
In the status log, the paper jams will come with an error code number that can help
determine the cause of the problem as well.
Is that the 13.5 that appears on the display or is it something else?
