6.5.4  WASTE INK TANK FULL SENSOR 
 
 
The waste ink full sensor [A] is a “smart” reflective photosensor. The photosensor 
measures the changes in the density of the ink materials in the tank. This lets you 
know when the tank is full. 
A prompt shows the printer needs maintenance when the sensor detects the near-
full condition. You can use the printer to print the following amounts of print jobs at 
the time the maintenance alert is displayed: 
•  J003: 200 prints 
•  J001: 100 prints 
These are only rough estimates. Fewer pages will be printed if many normal and 
full print head cleanings are done after the maintenance alert. 
You cannot use the printer when SC 992 (waste tank full error) is displayed. At this 
time you must replace the waste ink tank.
