maintenance functions and configuration settings can be made in this mode.
1.7.5.1 Ink Levels (CX8300/TX400 series only)
The current ink levels of each of the cartridges are displayed in bar chart by the rules
described below. After displaying the ink levels, the next operation can be selected
from the following two options; “End the ink levels display” or “Change Ink
Cartridge”.
• The bar chart is displayed in the order of cyan, magenta, yellow, and black from the left.
• When initial filling is completed, or after replacing the cartridge, the ink level becomes
100% (full).
• The ink level is indicated in increment of 1%. Lower than 1% is rounded down.
• When the ink level becomes lower than 10%, “!” icon appears to notify the user of the ink
low status.
