pantum m6550nw toner not detected — chip, contacts & reset
pantum m6550nw toner not detected usually appears when the printer can’t read the cartridge ID chip or the contacts don’t apply enough pressure. Use our pantum m6550nw toner not detected guide to clean the pins, reseat correctly, choose a firmware-compatible reset chip, and lock in a stable setup that won’t drop mid-print.
What the message really means
When the M6550NW boots or begins a job, it validates the toner cartridge’s chip. If the chip pads are oxidized, a spring pin is stuck, the front door doesn’t fully latch, or the firmware rejects the chip family, the device shows “Toner Not Detected.” The fix is methodical: contact → fit → chip → firmware → driver/queue hygiene.
