Accuracy: The margin of error of detection accuracy is +/-10% in normal printing.

The margin of error is likely to be large in the following specific print patterns:

When printing continuously using any one of the CMY colors of ink

-> As the remaining ink level is calculated by total counted dot values of 3 colors of ink, if

any of the C/M/Y inks is heavily consumed, the margin of error for remaining ink

increases.

When performing continuous BK solid printing

-> With continuous printing, ink flow from the tank to the ink chamber can be interrupted,

after which ink remains unused in the tank.

Reset procedure: Perform the following operations from the printer driver’s Maintenance:

1. In Low Ink Warning Setting, enable Display low ink warning.

2. In Ink Counter Reset, reset the applicable ink counter(s).

Note: Be sure to reset the ink counter from the printer driver’s Maintenance after replacing ink tanks.

- Due to user error, the actual remaining ink level does not match the indicated remaining ink level,

resulting in “ink out”, etc.

User error: Forgetting to reset the ink counter / ink counter reset other than when replacing ink

tanks.

- Due to the specific print pattern, the actual remaining ink level does not match the indicated remaining

ink level, resulting in “ink out”.

Specific print pattern: Continuous printing using any one of the CMY colors of ink / continuous

BK solid printing, etc.

(5) Print head deep cleaning

The printer has a print head deep cleaning (refreshing) function.

Print head deep cleaning (refreshing):

This is a deep cleaning function in order to resolve print failure due to ink clogging

the print head. (The black ink is pigment-based, and clogs easier than other

dye-based ink.)

Perform from the printer driver’s Maintenance.

- Excessive ink consumption when conducting print head deep cleaning repeatedly. (The amount of ink

used is approx. 10 to 15 times the normal manual cleaning amount.)
