Solutions

Diagnostic quick-check

If you see faded prints or vertical streaks before the C-2259 appears, this is a sign that the toner is not being fed correctly. Listen to the device while it attempts to work upon power-on; if you hear a clicking sound, the motor is jammed.

Step-by-step solution

  1. Power off the device and unplug it.
  2. Remove the four toner cartridges.
  3. Verify that each cartridge's gears rotate freely.
  4. Observe if there are any toner accumulations in the connectors.
  5. Reinsert the cartridges ensuring they are perfectly aligned.
  6. Power on the device; if the error persists, an internal supply motor requires replacement.

Prevention and maintenance

Avoid shaking cartridges unnecessarily as this can spill toner into the gears. Clean the internal area with a dry cloth only when necessary.

When to call a technician

If the error is persistent, it is a mechanical failure of the feed motor that requires disassembly of the main unit.
