Brother® Color Laser One-Year On-Site Limited Warranty(USA only)
What Brother will do:  
If the problem reported concerning your
Machine and/or accompanying Consumable
and Accessory Items is covered by this
warranty and
 if you first reported the problem
to Brother or an Authorized Service Center
within the applicable warranty period, Brother

your report of a possible defect to determine
whether a defect exists, and if it does exist,
Brother or an Authorized Service Center will
provide “On-site Warranty Service” during
“Normal Working Hours” and will repair the
Machine and/or accompanying Consumable
and Accessory Items at no charge to you for
parts or labor. “On-site Warranty Service”
shall consist of the remedial service, as
necessitated by normal usage, to restore this
product to good operating condition at your
location and does not guarantee
uninterrupted operation of this Product.

ALL OTHER WARRANTIES, WRITTEN OR
ORAL, WHETHER EXPRESSED BY
AFFIRMATION, PROMISE, DESCRIPTION,
DRAWING, MODEL OR SAMPLE.  ANY
AND ALL WARRANTIES OTHER THAN

the  final expression and the exclusive and
only statement  of Brother’s obligations to

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 Limited Warranty (and Brother’s obligation to you) may not be changed in
any way unless you and Brother sign the

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 MFC/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 MFC/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
MFC/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 MFC/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 MFC/Facsimile machine to operate properly.
Neither Brother nor anyone else involved in the development, production, or delivery of this
MFC/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
