<Possible problems with this function>
- When a once-used ink cartridge is installed, the actual remaining ink level is not detected, and an
error indicating the remaining ink amount is unknown occurs.
Pressing the OK button will clear the error, and printing can be done. However, the function to
detect the remaining ink amount is disabled (ink status is not displayed).
e.g.: An ink cartridge was once used in another printer.
A current ink cartridge is removed from the printer. -> A new ink cartridge is installed. ->
The removed ink cartridge is installed again after removing the new ink cartridge.
- Due to the specific print pattern, the actual remaining ink level does not match the indicated
remaining ink level.
This is because a detection error can be large in specific print patterns (such as continuous
printing using any one of the Photo /CL three colors of ink or continuous solid printing, etc.).
(5) Deep cleaning
The printer has a deep cleaning (refreshing) function.
Deep cleaning (refreshing):
This is a deep cleaning function in order to resolve print failure due to ink clogging
the nozzles.
<Possible problems with this function>
- Excessive ink consumption when conducting deep cleaning repeatedly. (The amount of ink used is
approx. 4 times the normal manual cleaning amount.)
