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 103.
●
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 loaded paper 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
Printing on page 42). 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 159.
●
Check that your ink cartridges and printheads have not passed their expiration dates: see
Maintain
the ink cartridges on page 97.
●
Avoid touching the paper while printing is in progress.
