Minolta Magicolor 2450 Toner Wipes Off

[ian_gendreau]

I just got a brand new Magicolor 2450. Have printed maybe 100 pages
and still having the same problem. Print quality is terrible, because
the toner isn't "sticking". I've tried all sorts of media... regular
copy paper, heavier stock, envelopes, photo paper... all items that
work in any of our other lasers... After I print, I can wipe my thumb
across the page, and all the powder from the toner just wipes off?
Driving me crazy? How do I fix this??

The fuser has failed!

Ian-

As NM said, the fuser isn't working. When you opened up the box, did you
follow all directions to setup the machine? Might there be some cardboard
packing or strips of tape inside the printer that weren't removed before
plugging it in?

You might unplug the printer and check to see that any replaceable modules
are firmly seated and locked into position. Often un-plugging and
re-plugging can clean-up a module's dirty electrical contacts.

Hi Ian,

Your printer is defective. The fuser is not functioning. The way laser
printers work is that the powdered toner (which is a mixture of
pigments, dyes and plastic power) is transferred onto the paper through
one of several methods, and then the paper goes through a couple of
rollers one or more of which are heated to a temperature that will fuse
or melt the toner powder onto the paper. If that fuser is not heating
at all, or not getting hot enough, the toner powder will not melt and
fuse to the paper, and as you report, the color will come off the paper
when it comes out of the printer.

I would return the printer to the store where it was purchased. The
problem could be a s simple as a bad fuse, or as complex as a bad fuser
core (which is sometimes a lamp which provides the heat), a bad
thermostat, or more, but either way, best to start with a new unit.

Had the same problem with mine except it was only on the right side of the
paper.

Open the comer and find the two gray levers on the left and right sides of
the paper path. They should be marked with an envelpe icon.
Make sure that these are fully forward. This will increase pressure
against the fuser. With these levers in the rearward postion you will be
able to print on envelopes.

I used to have a 2200 and it had a fuser oil roller that had to be
regularly replaced, if I didn't it would do something similar. You
could try re-seating everything.

Obviously the fuser isn't fusing the toner to the paper.
It's either the fuser isn't hot enough, the paper isn't
making good contact (pressure setting) or the
fuser isn't heating at all.
If it worked ok when you bought it and doesn't now it
may be failure of the fuser control circuit, commonly
a triac and opto-coupler combination. The main
problem being sourcing the correct components,
and the expertise to fit them. More a service
engineers job, they just swap whole boards.
As it's "brand new" I'd go for a warranty fix,
or try for a refund "never worked, unfit for purpose"
and consider a different model.
The trouble with exchange for a new one of
the same model, is it may be a batch or model
issue, you get the same again, with the same
problem.
Like cars, that sometimes have to do a recall
to fix all of them.
