For details of recommended papers, see "How do I select supported paper types?" on page 32. ● Make sure that the paper type selected in the front panel is the same as the paper type loaded into the printer. To check this, highlight the or icon on the front panel. ● Bear in mind that roll paper will generally give better print quality than a single sheet of the same kind of paper. When you are using single sheets of paper, we strongly recommend that you always set the print quality to Best. ● Check that you are using the most appropriate print quality settings for your purposes (see "How do I choose print quality settings?" on page 68). You are most likely to see print quality problems if you have set the print quality to Fast. ● To maintain the best print quality at the expense of speed, change the Printhead monitoring setting to Intensive. See "How do I manage printhead monitoring?" on page 51. ● Check that your environmental conditions (temperature, humidity) are suitable for high-quality printing. See "Tell me about environmental specifications" in the User's Guide. 127
