Most of small businesses
that own the Brother MFC-8480DN or the MFC-8890DW are familiar with the need to
replace toners and drums every once in a while. The fuser, on the other hand,
is another essential part of the printer that many of our customers do not know
how to replace or do not know that they need to replace the fuser until the
warning message start to appear.
The fuser is the part
that heats the toner and fuse the powder in place to produce the final print
out. The part only needs to be replaced about every 100,000 pages and it can be
years for most business to see the warning message appear on their screen.
Because not many people are familiar with the fuser, we would like to share
detailed instructions with you on how to reset the counter and replace the
fuser. You can choose to reset the fuser counter if you feel like the print
outs are doing okay and really do not need to replace the part until toner
powder start to smear off from your final print out.

1. Press the 3 and 9
buttons on the control panel at the same time
2. The display will say

3. Scroll down to FUSER

4. The screen will
display (1) Reset (2) Exit. Press 1 to reset.
5. The machine will

But right now I have a problem that even when there are no any paper I have massage that I have it!
ReplyDeleteDear Mr. Waschlerner,
DeleteThank you for the comment. Usually for Brother printers, the control panel should show where the paper was jammed inside the machine. Sometimes the paper gets stuck inside and cannot be seen without moving out the trays, etc. Hope this helps!
