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
Order paper on page 113.
●
Make sure that the paper type selected in the front panel is the same as the paper type loaded into the
printer (see
View information about the paper on page 42). 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
Printing
on page 50). 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 167.
●
Check that your ink cartridges and printheads have not passed their expiration dates: see
Maintain the
ink cartridges on page 107.
