Brother 46: distinguish almost-full firmware case from full absorber
Evidence linked to this decision

Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
The full display changes the answer. On MFC-250C/290C/490CW, Print Unable 46 means absorbers are almost full and ROM OA-OD has one official firmware branch; OE or later goes to service. Machine Error 46 means the absorber pad is full and needs engineer replacement.
Safety first
Stop and check this first
- Do not use hidden maintenance-mode counter-reset recipes. They can suppress the warning without replacing the full absorber.
Safe checks you can perform
- Capture evidence before clearing it
- Use firmware only for ROM OA-OD
Leave these tasks to a qualified professional
- Do not attempt this professional task: Quote the physical absorber service, not a counter reset
What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Quote the physical absorber service, not a counter reset
What they doGive the model, exact wording, ROM version and firmware outcome. Ask whether the quote includes absorber-pad replacement, waste-ink cleanup and the required service counter procedure; compare that complete quote with a replacement printer before authorizing work.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Capture evidence before clearing it
No special tools
Procedure
Photograph the complete wording and exact model. If it says Print Unable 46 on MFC-250C/290C/490CW, press Stop/Exit and then # plus * together to read the first two ROM characters.

Use firmware only for ROM OA-OD
No special tools
Procedure
Back up or print stored faxes first, use Brother's exact model updater, and do not interrupt power. ROM OE or later does not need this update and goes directly to service options.
Firmware can erase stored faxes; interruption can corrupt memory and require service.

What it means
A counter reset cannot remove stored waste ink. The only documented non-service exception is the narrow ROM check for three named models and the exact Print Unable wording; firmware must not be interrupted and can erase stored faxes.
Warnings and stop conditions
- Higheditorial warning
