Light patches of print appear on the image. How can I correct this?

Description of Solution 200000024952

Clean the print head. Follow the instructions in "Maintaining the Printer" in the User’s Guide.

Print a configuration page; verify the density setting is set to 7. Increase the print density setting if it is 5 or below. (Reference the User’s Guide).

The printer requires smooth paper to work properly. Make sure the paper does not have any deformities (dents or wrinkles.) It should lie flat and the surface should be smooth (it should not have a defective or uneven surface coating.)  Perform a test print using a different pack or roll of paper.

For best results use Genuine Brother Thermal Media

If the manufacture date in the “LOT #” on the product is “A”, “B”, or “C” please call Brother Mobile Solutions Customer Service at 1-800-543-6144. The instructions for locating the manufacture date are:

1)    Find the label on the box. It should say “Genuine Brother Supplies”. The lower right corner will contain a “LOT #”. Example” “LOT #:689BM10

2)    If the 5 character from the left, the second alpha character, is “A”, “B”, or “C” you have potentially defective paper.

3)    Recommendations:


·         For the suspect product that has been shipped to you between the dates cited above, Brother Mobile is initiating a proactive, full exchange of the suspect product with replacement product that meets our quality standards. We expect to be able to fulfill these exchanges starting with a Monday, April 25, 2011, arrival date.

·         We further recommend you responsibly dispose of or recycle any suspect product locally.

·         In the meantime, we are recommending that you DO NOT USE any of these suspect products.

·         For a limited number of more urgent situations, we have established a “hotline” process where you can call Brother Mobile’s toll-free number and request an expedited exchange of the suspect product that we will fulfill at no cost. 

·         Finally, there may be some segment of our customer base for whom their business process relies on the ability to store / archive a thermal image for a longer period of time (up to 7 years). For those customers with a longer-term storage need, we strongly recommend creating a duplicate image.



The machine has a one year limited depot warranty. If the machine requires service, call Brother Mobile Solutions Customer Service at 1-800-543-6144 Monday through Friday, excluding holidays for a Return Authorization number.
