9 Troubleshooting print-quality issues
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 29.
●
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 19). 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 Using your printer.
●
Check that your ink cartridges and printheads have not passed their expiration
dates: see
Maintain the ink cartridges on page 27.
●
Avoid touching the paper while printing is in progress.
