Corrective Action Follow these steps to prepare the printing environment. 1. Use the same version of firmware or printer driver. 2. Specify the same value for all settings items. Banding in different colors occurs Cause Corrective Action The paper feed amount is out of adjustment. Adjust the feed amount. (See "Adjusting the Feed Amount.") →P.673 Printing does not proceed smoothly because print jobs are interrupted during transmission. Exit other applications and cancel other print jobs. In the Control Panel menu, Adj. Priority is set to Print Length. Setting Adj. Priority to Print Quality in the Control Panel menu and adjusting the feed amount may improve results. (See "Adjusting the Feed Amount.") →P.673 The Printhead is out of alignment. Adjust the Printhead alignment. (See "Automatic Adjustment to Straighten Lines and Colors (Head Posi. Adj.).") →P.665 The Printhead nozzles are clogged. Print a test pattern to check the nozzles and see if they are clogged. (See "Checking for Nozzle Clogging.") →P.795 Streaks may occur if you set the Print Quality too low. Choose a higher level of Print Quality in the Advanced Settings of the printer driver and try printing again.
