Print-quality issues General advice When you have any print-quality problem: ● To achieve the best performance from your printer, use only genuine manufacturer's supplies and accessories, whose reliability and performance have been thoroughly tested to give trouble-free performance and best-quality prints. For details of recommended papers, see Using your product. ● Make sure that the paper type selected in the front panel is the same as the paper type loaded into the printer. At the same time, check that the paper type has been calibrated. Also make sure that the paper type selected in your software is the same as the paper type loaded into the printer. CAUTION: If you have the wrong paper type selected, you could experience poor print quality and incorrect colors, and perhaps even damage to the printheads. ● Check that you are using the most appropriate print-quality settings for your purposes (see Using your product). You are likely to see lower print quality if you have moved the print-quality slider to the 'Speed' end of the scale, or set the custom quality level to Fast. ● Check that your environmental conditions (temperature, humidity) are in the recommended range. See Using your product. ● Check that your ink cartridges and printheads have not passed their expiration dates: see Using your product. Horizontal lines across the image (banding) If your printed image suffers from added horizontal lines as shown (the color may vary): 1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel and in your software. 2. Check that you are using appropriate print-quality settings for your purposes (see Using your product). In some cases, you can overcome a print-quality problem merely by selecting a higher print-quality level. For instance, if you have set the Print Quality slider to Speed, try setting it to Quality. If you change the print-quality settings, you may wish to reprint your job at this point in case the problem has been solved. 4 Chapter 2 Troubleshooting print-quality issues ENWW
