, only the life end cartridge code is displayed.

*1: 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 2.5K, the remaining quantity of the toner cartridge, 
though it is a new one, is displayed as 25-0%.

*2: Selection of Display/Not Display can be made with SIM26-69. (Default: Not Display)
*3: Setting can be made with SIM26-69. (Default: 0 sheet)
*4: 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 drum cartridge is replaced with a new one, the print counter, the accumulated traveling distance counter, the accumulated rotation

number counter, and the usage day counter are automatically cleared.

• If the above guidance does not disappear when the drum cartridge is replaced, SIM24-7 must be executed to clear the print counter, the

accumulated traveling distance counter, the accumulated rotation number counter, and the usage day counter.

• When the developer cartridge is replaced with a new one, the print counter, the accumulated traveling distance counter, the accumulated

rotation number counter, and the usage day counter are automatically cleared, and the initial setting of the toner density is automatically exe-
cuted.

• When SIM26-55 setting is set to ENABLE, the initial setting of the toner density is executed.
• 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 SIM25-2.

• When the drum cartridge is replaced with a new one, the print counter, the accumulated traveling distance counter, the accumulated rotation

number counter, and the usage day counter are automatically cleared. If SIM26-55 setting is set to ENABLE in that case, the guidance for
execution of the automatic adjustment of the engine is displayed.

• If SIM26-55 setting is set to DISABLE, SIM46-74 must be used to execute the automatic adjustment of the engine.
• If the above guidance does not disappear when the drum cartridge is replaced, SIM24-7 must be executed to clear the print counter, the

accumulated traveling distance counter, the accumulated rotation number counter, and the usage day counter, and the engine automatic
adjustment must be executed.

• The above display disappears when the counters are cleared.

Judgment is made at the earlier timing of the developer print counter or the developer accumulated rotation number counter.
The developer rotation number is synchronized with the drum motor rotation number.

After replacement of developer, use SIM25-2 to set the toner density control level. By this setting, the developer counters (the developer print
counter and the developer accumulated traveling distance counter) are cleared.
