After contacting Brother or a Brother
Authorized Service Center, you may be
required to deliver (by hand if you prefer) or
send the Product properly packaged, freight
prepaid, to the Authorized Service Center
together with a photocopy of your bill of sale.
You are responsible for the cost of
shipping, packing product, and
insurance (if you desire). You are also
responsible for loss or damage to this
Product in shipping.
What Brother will do:
First 2 Years
: If the problem reported
concerning your Machine and/or
accompanying Consumable and Accessory
Item(s) is covered by this warranty and
if (i)
you first reported the problem with your
Machine to Brother or an Authorized Service
Center within 2 years from the original
purchase date or (ii) you first reported the
problem with the accompanying
Consumable and Accessory Items to Brother
or an Authorized Service Center within the
earlier of 90 days from the original purchase
date or the rated life of the item, Brother or its
Authorized Service Center will repair or
replace the Machine and/or accompanying
Consumable and Accessory Item(s) at no
charge to you for parts or labor. The decision
as to whether to repair or replace the
Machine and/or accompanying Consumable
and Accessory Item(s) is made by Brother in
its sole discretion. Brother reserves the right
to supply a refurbished or remanufactured
replacement Machine and/or accompanying
Consumable and Accessory Item(s) and use
refurbished parts provided such
replacement products conform to the
manufacturer's specifications for new
product/parts. The repaired or replacement
Machine and/or accompanying Consumable
and Accessory Item(s) will be returned to
you freight prepaid or made available for you
to pick up at a conveniently located

DCP LIMITED WARRANTY (USA)

vi
What happens when Brother elects to
replace your Machine:
When a replacement Machine is authorized
by Brother, and you have delivered the
Machine to an Authorized Service Center,
the Authorized Service Center will provide
you with a replacement Machine after
receiving one from Brother. If you are
dealing directly with Brother, Brother will
send to you a replacement Machine with the
understanding that you will, after receipt of
the replacement Machine, supply the
required proof of purchase information,
together with the Machine that Brother
agreed to replace. You are then expected to
pack the Machine that Brother agreed to
replace in the package from the replacement
Machine and return it to Brother using the
shipping bill supplied by Brother in
accordance with the instructions provided by
Brother. Since you will be in possession of
two machines, Brother will require that you
provide a valid major credit card number.
Brother will issue a hold against the credit
card account number that you provide until
Brother receives your original Product and
determines that your original Product is
entitled to warranty coverage. Your credit
card will be charged up to the cost of a new
Product only if: (i) you do not return your
original Product to Brother within five (5)
business days; (ii) the problems of your
original Product are not covered by the
warranty; (iii) the proper packaging
instructions are not followed and has caused
damage to the product; or (iv) the warranty
period on your original Product has expired
or has not been sufficiently validated with a
copy of the proof of purchase (bill of sale).
The replacement Machine you receive (even
if refurbished or remanufactured) will be
covered by the balance of the warranty
period remaining on the original Product,
plus an additional thirty (30) days. You will
keep the replacement Machine that is sent to
you and your original Machine shall become
the property of Brother. Retain your
original Accessory Items and a copy of
the return shipping bill, signed by the
courier.
Limitations:
Brother is not responsible for damage to or
loss of any equipment, media, programs or
data related to the use of this Product.
Except for that repair or replacement as
described above, Brother shall not be liable
for any direct, indirect, incidental or
consequential damages or specific relief.
Because some states do not allow the
exclusion or limitation of consequential or
incidental damages, the above limitation
may not apply to you.
THIS WARRANTY IS GIVEN IN LIEU OF
ALL OTHER WARRANTIES, WRITTEN OR
ORAL, WHETHER EXPRESSED BY
AFFIRMATION, PROMISE, DESCRIPTION,
DRAWING, MODEL OR SAMPLE. ANY
AND ALL WARRANTIES OTHER THAN
THIS ONE, WHETHER EXPRESS OR
IMPLIED, INCLUDING IMPLIED
WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR
PURPOSE, ARE HEREBY DISCLAIMED.
• This Warranty is the only warranty that
Brother is giving for this Product. It is the
final expression and the exclusive and only
statement of Brother's obligations to you. It
replaces all other agreements and
understandings that you may have with
Brother or its representatives.
• This warranty gives you certain rights and
you may also have other rights that may
vary from state to state.
• This Warranty (and Brother's obligation to
you) may not be changed in any way
unless you and Brother sign the same
piece of paper in which we (1) refer to this
Product and your bill of sale date, (2)
describe the change to this warranty and
(3) agree to make that change.
Important:
We recommend that you keep
all original packing materials, in the event
that you ship this product.

BROTHER MULTIFUNCTION CENTER/FACSIMILE MACHINE
LIMITED WARRANTY
(Canada only)
Pursuant to this limited warranty of 1 year from the date of purchase for labour and parts,
Brother International Corporation (Canada) Ltd. (“Brother”), or its Authorized Service
Centers, will repair this DCP/Facsimile machine free of charge if defective in material or
workmanship. This Limited Warranty does not include cleaning, consumables
(including, without limitation, print cartridges, print head, toner and drum) or damage
caused by accident, neglect, misuse or improper installation or operation, any damage
caused from service, maintenance, modifications, or tampering by anyone other than a
Brother Authorized Service Representative, or from the use of supplies or consumable
items that are non-Brother products. Operation of the DCP/Facsimile machine in excess
of the specifications or with the Serial Number or Rating Label removed shall be deemed
abuse and all repairs thereafter shall be the sole liability of the end-user/purchaser. In
order to obtain warranty service, the DCP/Facsimile machine must be delivered or
shipped freight prepaid by the end user/purchaser to a “Brother” Authorized Service
Center, together with your Proof of Purchase in the form of a Sales Receipt.
For laser products: Failure to remove the Toner Cartridge (and Toner Drum Unit on
applicable models) during shipping will cause severe damage to the DCP/Facsimile and
will VOID the Warranty. (Refer to your User’s Guide for proper packaging.)
For ink-jet products: Do not remove the ink cartridges during shipping. Damage to your
print head resulting from packing without the ink cartridges will VOID your warranty.
(Refer to your User’s Guide for proper packaging.)
BROTHER DISCLAIMS ALL OTHER WARRANTIES EXPRESSED OR IMPLIED
INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, EXCEPT TO
THE EXTENT THAT ANY WARRANTIES IMPLIED BY LAW CANNOT BE VALIDLY
WAIVED.
No oral or written information, advice or representation provided by Brother, its
Authorized Service Centers, Distributors, Dealers, Agents or employees, shall create
another warranty or modify this warranty. This warranty states Brother’s entire liability
and your exclusive remedy against Brother for any failure of the DCP/Facsimile machine
to operate properly.
Neither Brother nor anyone else involved in the development, production, or delivery of
this DCP/Facsimile machine shall be liable for any indirect, incidental, special,
consequential, exemplary, or punitive damages, including lost profits, arising from the
use of or inability to use the product, even if advised by the end user/purchaser of the
possibility of such damages. Since some Provinces do not allow the above limitation of
liability, such limitation may not apply to you.
This Limited Warranty gives you specific legal rights and you may also have other rights
which vary from Providence to Providence.
Warranty Service is available at Brother Authorized Service Centers throughout
Canada. For Technical Support or for the name and location of your nearest Authorized
Service Center call 1-877-BROTHER.

2 - 2 PAPER
Caution
Do not use ink jet paper. It may cause a paper jam and damage your
DCP.
Choosing acceptable paper
We recommend that you test paper (especially special sizes and
types of paper) on the DCP before purchasing large quantities.
■
Avoid feeding label sheets that are partly used or your DCP will
be damaged.
■
Avoid using coated paper, such as vinyl coated paper.
■
Avoid using preprinted or highly textured paper, or paper with an
embossed letterhead.
For optimum printing, use a recommended type of paper, especially
for plain paper and transparencies. For more information on paper
specifications, call your nearest authorized sales representative or
the place where you purchased your DCP.
■
Use label or transparencies that are designed for use in
laser
printers.
■
For the best print quality, we recommend using long-grained
paper.
■
If you are using special paper and the paper has problems
feeding from the paper tray, try again using the manual feed tray
or multi-purpose tray.
■
You can use recycled paper in this DCP.
The output quality depends on the paper type and paper brand.

recommendations for paper that can be used with the

The DCP does not load paper.
The LCD shows Check
Paper or Paper Jam.
Check to see if the Check Paper or Paper Jam message appears on
the LCD. If it is empty, load a new stack of paper into the paper tray. If
there is paper in the paper tray, make sure it is straight. If the paper is
curled, you should straighten it. Sometimes it is helpful to remove the
paper, turn the stack over and put it back into the paper tray. Reduce the
amount of paper in the paper tray, and then try again. Check that the
manual feed mode or MP tray or MP mode is not selected in the printer
driver.
The DCP does not feed paper
from the manual feed tray.
Reinsert the paper firmly, load one sheet at a time. Make sure that
manual feed mode or MP mode is selected in the printer driver.
How can I load envelopes? You can load envelopes from the manual feed or MP tray. Your
application software must be set up to print the envelope size you are
using. This is usually done in the Page Setup or Document Setup menu
of your software. Refer to your software application manual.
What paper can I use? You can use plain paper, envelopes, transparencies and labels that are
made for laser machines. (For information on paper you can use, see
Printer operation keys in Software User’s Guide on the CD-ROM.)
How can I clear paper jams? See Paper jams.

that must be replaced after approximately 3,500 pages. Actual page
count will vary depending on your average type of original (i.e.,
standard letter, detailed graphics).
Discard the used toner cartridge according to local regulations,
keeping it separate from domestic waste. Be sure to seal the toner
cartridge tightly so toner powder does not spill out of the cartridge. If
you have questions, call your local waste disposal office.
We recommend that you clean the DCP when you replace the toner

Replacing the drum unit
The DCP uses a drum unit to create print images on paper. If the
LCD shows
Change Drum Soon
, the drum unit is near the end of
its life and it is time to purchase a new one.
Even if the LCD shows
Change Drum Soon
, you may be able to
continue printing without having to replace the drum unit for a while.
However, if there is a noticeable deterioration in the output print
quality (even before
Change Drum Soon
appears), then the drum
unit should be replaced. You should clean the DCP when you
replace the drum unit. (See
Cleaning the drum unit
.)
Caution
When removing the drum unit, handle it carefully because it contains
toner. If toner scatters and your hands or clothes get dirty,
immediately wipe or wash with cold water.
The drum unit is a consumable item, and it is necessary to
replace it periodically. There are many factors that determine
the actual drum life, such as temperature, humidity, type of
paper and how much toner you use for the number of pages per
print job. The estimated drum life is up to 20,000 pages. The
actual number of pages your drum will print may be significantly
less than these estimates. Because we have no control over the
many factors that determine the actual drum life, we cannot
guarantee a minimum number of pages that will be printed by
your drum.
