and Coated when printing EPSON Color Laser Coated Paper. In case when 
selected the standard envelope(C5, C6, C10 or Monarch), the printer setting 
will automatically change to envelope setting. If Envelope, Thick, Transprnc

 Change Toner C, Change Toner M, Change Toner Y, Change Toner K
Use them when replacing a toner cartridge before “uuuu Toner Cart Out” 
occurs. When the toner cartridge to replace is specified and the Enter button 
pressed, the panel displays “Please Wait” and the printer moves to the 
position for replacing the toner cartridge. Then, the printer displays “Replace 
Toner x” (x = C, M, Y or K that is specified) and enters the wait state. 
Normally this process will be finished at several seconds, but if the printer is 
entering the sleep mode, it may take several minutes occasionally. 
When this operation is executed, the sleep mode is released once and the printing 
process is not performed. Moreover, the Reset, Job Cancel, and Form Feed 
specified with EJL or MIB during this process become invalid. Reset All is valid 
during this process. This process ends when the cover is opened and closed

P O I N T
The remaining amount of toner of each toner cartridge, as 
measured on the engine side in the range from 0% to 100% in 
units of 2%, is returned to the controller. This state is always 
started from 100% even if 1.5K toner is installed. It is necessary to 
convert into the remaining amount on the controller side because 
the toner information received from the engine is a use rate.
C H E C K
P O I N T
The counter value is counted on the engine side. It is necessary to 
convert into the remaining amount on the controller side because 
the Photoconductor information received from the engine is a use 
rate.
