This method works for most users seeing a "Toner Low" or "Replace Toner" message.
If that doesn't work, try this variation:
| Post-Reset Issue | Solution | |------------------|----------| | Printer does not power on | Check power supply, try different outlet | | Still shows "Replace Toner" | Replace cartridge with genuine MLT-D101S or MLT-D111S | | Not detected by computer | Reinstall driver (Samsung Universal Print Driver) | | Prints blank pages | Toner cartridge empty or shutter not open |
This method resets the printer’s internal processor without erasing permanent settings.
Steps:
Outcome: Clears active errors, cancels current job queue, and resets communication buffers.
Before diving into the steps, it helps to understand why a reset might be necessary:
Before attempting any advanced reset, a soft reset can clear temporary errors caused by static charge or memory buffers. This is non-destructive, meaning it will not erase settings.
Steps:
When this works: Soft resets resolve frozen displays, failure to wake from sleep mode, or transient “paper jam” messages when no jam exists.
Use this method if you have refilled your toner or installed a new cartridge, but the printer still displays the red toner LED and refuses to print.
Method A: The Button Sequence
Method B: The "Fuse" Method (If Method A fails) Some Samsung ML-2165 cartridges require a physical reset fuse. If the button method does not work: how to reset samsung ml-2165 printer
The ML-2165 uses a memory chip on the toner cartridge to track page count. Once the chip indicates “empty,” the printer refuses to print, even if the cartridge still has toner. To reset this counter (often required after refilling toner), use the manual override sequence.
Steps:
Important: This only resets the printer’s perception of toner level, not the actual physical chip on the cartridge. If you have a replaced or refilled cartridge, this method works temporarily. For a permanent solution, you may need to replace the cartridge chip or use a chip-resetter device.
