A hub or USB flash drive with hub has
been connected to the USB direct
interface.
The ink absorber box or flushing box is
nearly full.
The ink absorber box or flushing box is
full. These components are periodic
maintenance items that may require
replacement after a period of time to
ensure optimum performance from your
Brother machine. Because these
components are periodic maintenance
items, the replacement is not covered
under the warranty. The need to replace
these items and the time period before
replacement is dependent on the number
of purges and flushes required to clean
the ink system. These boxes acquire
amounts of ink during the different purging
and flushing operations. The number of
times a machine purges and flushes for
cleaning varies depending on different
situations. For example, frequently
powering the machine on and off will
cause numerous cleaning cycles since the
machine automatically cleans upon power
up. The use of non-Brother ink may cause
frequent cleanings because non-Brother
ink could cause poor print quality which is
resolved by cleaning. The more cleaning
the machine requires, the faster these
boxes will fill up.
Repairs resulting from the use of non-
Brother supplies may not be covered
under the stated product warranty.

Reasons for cleaning are:
1. The machine automatically cleans
itself after you remove the power cord
and plug it back in.
2. After a paper jam has been cleared,
the machine automatically cleans itself
before the next received page is
printed.
3. The machine automatically cleans
itself after sitting idle for more than 30
days (infrequent use).
4. The machine automatically cleans
itself after ink cartridges of the same
colour have been replaced 12 times.
Order a new ink cartridge. You can
continue printing until the touchscreen
