Let’s clarify terminology first. The Epson M1100 resetter is not a physical tool like a screwdriver. It is a piece of software (a utility program) designed to communicate directly with your printer’s internal memory.
Epson printers contain a waste ink pad—a spongy absorbent material inside the chassis that captures excess ink from cleaning cycles. The printer uses a digital counter to track how many drops of ink have hit that pad. When the counter hits a pre-set limit (usually around 15,000–20,000 pages), the printer self-bricks to prevent ink from physically overflowing and destroying your desk.
The “resetter” does two things:
Critical Warning: The software does not remove physical ink from the pads. If you reset without cleaning or replacing the pads, you risk a messy, expensive ink flood. epson m1100 resetter
Epson periodically issues firmware updates that block known resetter commands. After a firmware update, the resetter may no longer work, and downgrading is often impossible.
Epson’s official service manual for the M1100 requires:
Do not ignore the physical waste ink pad. Resetting the counter without addressing the pad is like resetting your car’s “Check Engine” light without adding oil. Let’s clarify terminology first
The resetter uses USB Bulk Transfer (endpoint 0x01 for out, 0x82 for in) with vendor-specific requests. Example payload (hexadecimal):
1B 40 (Initialize)
1B 52 03 (Select service command mode)
1B 43 (Reset waste counter)

The resetter reads the current counter value from EEPROM address 0x2F8 (example – actual address varies), writes 0x00 0x00 0x00 to that location, and writes the new checksum.
The “Service Required” error should be gone. You can now print again. Critical Warning: The software does not remove physical
Inside your M1100, there is a sponge-like component called the “maintenance box” or “waste ink pad.” During print head cleaning cycles, a small amount of excess ink is flushed into this pad. The printer tracks exactly how much ink has been dumped there. When the counter hits a pre-set limit (usually around 15,000-20,000 pages), the printer locks down to prevent ink from spilling inside the machine.
The Resetter’s Job: It resets that counter back to zero. This does not physically clean or replace the pad; it simply tells the printer’s firmware that the pad is “new” again.
Warning: If the physical pad is already full of ink, resetting the counter can lead to ink leakage and permanent damage to your printer. We will cover when to reset versus when to replace the pad later.
