Initial Check Items (System Cleaning)
Before running System Cleaning, check that the printer power is on.
Then check the following items:
• When you ran Nozzle Check, were there areas where the print was smeared or unprinted areas?
• Did the condition not improve even after Deep Cleaning was run?
• Are the remaining ink levels insufficient?
◦ Visually check whether the remaining ink levels are insufficient.
If System Cleaning is run when the remaining ink levels are insufficient, it may trigger a failure.
◦ If you selected All Colors or Black for Ink Group, check that all remaining ink levels are at least
at the single dot position indicated on the ink tanks. (The color inks are consumed even if Black
was selected.)
If you selected Color, check that the remaining ink levels for all color inks are at least at the single
dot position indicated on the ink tanks.
◦ If any remaining ink level is below the single dot position,
dot position. However, if Remaining Ink Notification Settings is enabled, replenish all remaining
ink levels to the upper limit line indicated on the ink tanks, regardless of the Ink Group setting.
