Brother Printer Error Code 77 — What It Means & How to Fix It

What Does This Error Mean?

Error 77 on a Brother inkjet printer means the ink absorber pad is completely full. This pad collects waste ink from cleaning cycles. The printer will not print until the absorber is replaced or the counter is reset.

Common Causes

The waste ink absorber pad has been fully saturated after years of cleaning cycles
Frequent print head cleaning operations have filled the pad faster than normal
High total print volume over the printer's lifetime has generated excess waste ink
The waste ink counter has hit its maximum value
Using third-party ink that requires more frequent cleaning cycles

How to Fix It

Do not attempt to print when error 77 is showing. The pad is full and may leak ink inside the printer.

Leaking waste ink can permanently damage the printer's internal circuit board.
Contact a Brother service center to have the ink absorber pad replaced.

This is the correct long-term fix and includes resetting the waste ink counter.
Alternatively, look for a Brother ink absorber reset tool or adjustment program online.

Some third-party utilities allow you to reset the counter — this lets you keep printing but does not empty the physical pad.
If you use a counter reset tool, be aware the pad is still full of ink.

Plan to have the pad physically replaced within a reasonable time to prevent leaks.
After a pad replacement, Brother service centers will reset the counter as part of the service.

You can then print normally again without risk of ink leaking inside the machine.

When to Call a Professional

Error 77 requires either a counter reset (temporary) or a physical pad replacement (permanent fix). Brother service centers replace ink absorber pads for $50 to $100. This repair stops the overflow risk and resets the printer properly.

Frequently Asked Questions

Can I replace the ink absorber pad myself?

It is technically possible but very messy. The pad is saturated with ink and will stain anything it touches. Most people opt for a service center visit for this particular repair.

What happens if I ignore error 77 and keep printing?

The ink absorber will overflow and waste ink will spread inside the printer. This can reach the circuit board and cause permanent, unrepairable damage. Do not print when error 77 is showing.

How long does it take for the absorber to fill up again after a reset?

For typical home use, it can take several years. Frequent head cleaning cycles fill the pad much faster. Avoid running head cleaning unless you actually see print quality problems.
