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
●
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, use the
View information
key on the front panel. 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
). 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
Environmental specifications on page 186
.
●
Check that your ink cartridges and printheads have not passed their expiration dates: see
Maintain the ink cartridges on page 124
