Head Cleaning
In case abnormal printing occurs, you can enter the printhead cleaning mode through the control panel operation. Also, to keep the printer in the best condition, the printer automatically selects the cleaning level including flushing and carries it out even while printing. Follow the steps below to enter the printhead cleaning mode. 1. Press Pause button to put the printer into the off-line status. Pause LED goes off. 2. Clean the black or color printhead by pressing the corresponding Cleaning...
