Brother dcp-7010 VIBRATES!

G

ggreekx

I don't know how it is called but the roller that is in contact with
the fuser isn't perfectly round and the printer vibrates a bit while
printing.
This printer came to me today from brother because had problems (scan
noise) with my first one and should be replaced(dcp-7010).
What should i do?Should i call them again or should i wait and see if
the roller becomes round?

PS:No problem with the print quality.
PS2:This printer isn't brand new but refurbished :(

Not sure which roller you are referring to, if it is the redish brown one that
runs the width of the printer then that is the fuser pressure roller (Brother
may give it a different name). If this roller is not round then you should
certainly talk to Brother again, I know its a pain but there is no way the
roller is going to become round and in time will probably get worse resulting
in improper fusing or paper jams. Tell them about the vibration, laser printers
in good condition do not noticeably vibrate.

Well, if it was mine I wouldn't live with it. I would ask Brother to
fix/replace it.
Pity eh?

:( i'll call them back again.I am afraid that maybe they give me a
printer more used than this one.
This one has 3500 pages printed.

Are you sure that this brown roller won't return in its first round
state if i print 500-1000pages?
is it deformed permanently?
Why happened that?

Thank you very much again!

I have never seen a pressure roller deform in this particular way; it is
likely, in my opinion, that it was incorrectly manufactured. I can't imagine
that it will return to a correct shape.

I contact them today via mail and send them a sample which shows that
the roller is defective.
Here is the picture

Fascinating, I have never seen such a pronounced crease from a laser printer.
If you measure the distance (page viewed long side vertically) between the
start of one crease and the start of the next crease....is it exactly 79mm?
Looking at the image it certainly looks like a fuser (fixing unit) problem. If
it is 79mm then that is confirmed.
There are only three rollers in the printer with a circumference that is
similar to the distance between the creases in your image. The pressure roller
(79mm), the drum (74mm) and the hot roller in the fixing unit. The last two of
these are hard rollers and it is almost inconceivable that they could develop
this sort of problem, the pressure roller is a relatively soft roller and could
deform this way.
Anyway, good luck. Brother should replace this printer for you.

79mm confirmed!
I am afraid that brother will give me another used printer with
possible other problems.
i must request a brand new or my old one fixed.
Thanks Tony for your help :)

Just an uneducated guess, but could it be a heating distribution defect?
It looks like either a "lump" in one roller (and I mean a lump, not
just an off centre bore) or that one part of the fuser/heater is way
hotter or colder than the rest. What if it is slipping a gear at one
point in the rotation? Could there be something stuck to the roller that
isn't supposed to be there (packaging, or some shipping item). The
definition of the defect seems very defined, which, as I think about,
probably doesn't support the heat distribution theory, since that would
be more gradual.

Anyway, to the OP, I would certainly NOT accept that printer as a
replacement for another with other defects.

BTW, Brother got better grades for customer service with Lasers than
several other companies, in the PC magazine survey, as memory serves, so
I'd continue to pursue this until it is right.

I think at this point you have every right to demand a thoroughly
pretested refurb or a new one. In some states of the US and in some
other locales with "lemon laws", on the third try they have to offer a
new one or your money back.

Thanks guys for your support.I have already sent them a mail explaining
the problem and attached the picture above.I'll call them on monday and
hope that this will be the last time i hear them :)

Yes, Brother does have a good reputation for after sales service, and their
monochrome laser printers are good quality.
As I said earlier in the thread, this is an unusually pronounced crease. I
suspect a gear with a missing tooth would cause paper jams but having said that
the crease does appear in the image to have signs of overheating so maybe what
is happening here is the fuser and the exit mechanism is stopping (gear
failure??) momentarily. I would also expect any deformity of this magnitude in
the roller to be easily visible to the eye, it is not hard to see portions of
the roller in this printer, no dissassembly is required. So my conclusion based
on entirely remote observation and giving it more thought is that this is more
likely to be a mechanical failure rather than a roller problem (I would love to
see the roller to be sure) or maybe even an electronic problem causing the
fuser and paper drive mechanism to slow down or even stop momentarily. All
somewhat academic now of course.

I believe you are referring to the fuser drum rather than the lamp.

It does look like possibly an abrasion in the teflon coating of the
drum, possible caused by it rubbing on the heat sensor that comes in
contact with the drum to determine if the fuser is hot enough. Many
laser printer have some remnant of this, but it usually indicates a
rather heavily used fuser drum. How old was your very first printer
when you sent it in for repair?

Got the "new" brother today.Everything seems ok but i noticed a black
vertical line on fuser lamp.
It isn't toner and seems to be on the internal surface.
Please check it and tell me what you think

That mark does not concern me. It indicates that the printer is probably
refurbished but based on my experience with Brother laser printers I would
expect the fuser to have a long and happy life. As a matter of fact it almost
certainly is toner, there is nothing else that it really could be. I have seen
these sort of marks on many fusers, especially those that use hard rollers. It
is not too difficult to clean these marks off, the hard part is getting the
fuser out of the printer so that you can do so. Under no circumstances however
should you attempt to clean the roller with anything that is even slightly
abrasive. There are specialised toner removers available, however if it were my
printer I would not do anything about it.
Good luck.
