- !Machine Error 46 is displayed at all; this is already a service-level condition.
- !The printer is older and out of warranty, but still worth repairing because it has a low page count otherwise.
What to check first
Step-by-step checks
- 1
Escalate
Stop trying to print normally because the machine is warning about a service-life limit, not a temporary print error.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Escalate
If the printer is still in warranty, contact Brother support before attempting any unofficial reset path.
- 3
Safe first step
Back up any urgent scanning workflow to another device if the unit is business-critical.
Background
What this message usually means
Brother uses Machine Error 46 when the ink absorber pad has reached its service limit. This is not a routine cartridge error. It means the machine’s waste-ink capacity has been consumed to the point where Brother expects an engineer or authorized service path to replace the absorber hardware.
Diagnosis
Likely causes
The waste-ink absorber has reached the end of its expected service life.
Repeated automatic head-cleaning cycles have filled the absorber over time.
The machine is tracking a service-limit counter that has now been reached.
Service
When service or replacement is more likely
- -This is a good example of a code where resetting counters without absorber replacement can create a messier failure later.
- -Treat 46 as a service-limit warning, not as a normal consumables prompt.
