InkBox full The ink absorber box or flushing box
needs to be replaced. These
components may require periodic
replacement to ensure optimum
performance from your Brother
machine. The replacement cycle
depends on the number of purges and
flushes required to clean the ink
system. The more cleaning the
machine requires, the faster these
boxes will fill up. The replacement is
not covered under the warranty.
The ink absorber box must be
replaced. Contact Brother
customer service or your local
Brother Authorised Service Centre
to have your machine serviced.
