Print Results Are Not Satisfactory
If print quality is poor, check the machine and printer driver settings for problems. If no problems are
apparent, check the print cartridge or other consumables. For details about handling paper, see
page 86 "Paper". For details about handling the print cartridges, see page 197 "Handling Print
Cartridges".
• If problems persist even after configuration checks indicate correct values, contact your sales or
service representative.
Prints are Unsatisfactory
This section explains how to troubleshoot the machine when printing is uneven (due to the wrong amount
of ink being used) or when prints are smudged, smeared, or blotchy.
Have you printed the nozzle check test pattern?
Print the nozzle check test pattern to check whether the print head nozzles are all ejecting ink properly,
and, if necessary, carry out head cleaning or head-flushing.
1. Execute Nozzle Check to determine the number of the clogged print head.
2. Perform Head Cleaning for the clogged print head.
3. Execute Nozzle Check to determine whether the problem has been eliminated.
4. If the problem persists, do not use the machine for 5 to 10 minutes.
By doing this, minute bubbles in the print head nozzle may disappear as the air in them dissolves
into the ink, resulting in unclogging.
5. Execute Nozzle Check to determine whether the problem has been eliminated.
If the problem persists, repeat Steps 1 to 5 a few more times.
Also letting the machine stand idle after repeating the procedure may help eliminate the clogging.
If the problem persists, perform Steps 1 to 5 again, but instead of performing "Head-cleaning" in Step 2,
perform "Head-flushing".
Head Flushing, which cleans the print head more thoroughly than Head Cleaning, consumes a lot of ink.
If the problem returns soon after it has been eliminated, set [Recycl.Ppr.Mode] in the [System] menu to
[On].
See page 131 "Nozzle Check", page 132 "Head-cleaning" and page 134 "Head-flushing".
Has the machine not been used for a long time?
The ink may be dry or the nozzles of the print heads may be clogged. Print the nozzle check test pattern
and clean the print heads as necessary.
