MX-C300P  MAINTENANCE  9 – 3

For CMYK only the life end cartridge code is displayed.

-  When the black drum cartridge does not reach the life end and only the color drum cartridge reaches the life end, black/white print can be 

performed but color print cannot be performed.

- When the developer cartridge is replaced with a new one, execute SIM24-5 to clear the print counter, the accumulated traveling distance

counter and the usage day. 

- If the above guidance does not disappear when the developer cartridge is replaced, the initial setting of the toner density must be executed

with the simulation, and the auto color calibration must be executed.

- When the initial setting of the toner density is executed, the counters are cleared and the above display disappears.

For KCMY only the life end cartridge code is displayed.

-  Detected by the toner motor rotation number and the pixel count (The value of larger life percentage is employed.)
   Since the life of the toner cartridge which is packed when shipping from the factory is 1.0K, the remaining quantity of the toner cartridge, 
   though it is a new one, is displayed as 25-50%.
- Selection of Display/Not Display can be made with Sim26-69. (Default: Not Display)
- When the black toner cartridge does not reach the life end and only the color toner cartridge reaches the life end, black/white print can be 
  performed but color print cannot be performed.

When the Toner collection container is replaced, the display disappears.
