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. Printing in [Fast] or [Standard] mode is faster and consumes less ink than in [Highest] or [High] modes, but the printing quality is lower.
The type of paper specified in the printer driver does not match the type loaded in the printer.
Load paper of the same type as you have specified in the printer driver.
Make sure the same type of paper is specified in the printer driver as you have loaded in the printer.
1. Press the [Stop] button and stop printing.
2. Change the type of paper in the printer driver and try printing again.
Printing does not proceed smoothly because print jobs are interrupted during transmission.
