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 “How do I select supported paper
types?” on page 94.
● 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 130). 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 113.
● Check that your environmental conditions (temperature, humidity) are suitable for
high-quality printing. See “Tell me about environmental specifications” on page 242.
