6 Troubleshoot print-quality issues General printing advice Use the following approach when you have any print-quality problem: ● Make sure that the substrate type that you select on the front panel, and in your RIP software, is the same as the substrate type that is loaded in the printer. Make sure that the substrate type has been calibrated. CAUTION: If you have the wrong substrate type selected, you could experience poor print quality and incorrect colors, and perhaps even damage to the printheads. ● Make that you are using the correct media profile for your substrate, or that you have followed the correct procedure to generate a new media profile (see Add a new substrate on page 41). ● Make sure that you are using appropriate print-quality settings in your RIP software. ● Make sure that you are using the correct ICC profile for your substrate and print-quality settings. ● Make sure that your environmental conditions (temperature, humidity) are in the recommended range. See the User's guide. ● Make sure that your ink cartridges have not passed their expiration dates. See Maintain the ink cartridges on page 22. ● Avoid touching the substrate while printing is in progress. Use the printhead status plot The printhead status plot consists of patterns that are designed to highlight printhead-reliability problems. It helps you to check the performance of the printheads that are currently installed in your printer, and to determine whether any printhead is experiencing clogging or other problems. Print the printhead status plot To print the printhead status plot: 1. Use the same substrate type that you were using when you detected a problem. 2. Check that the selected substrate type is the same as the substrate type that is loaded into the printer. 3. On the printer's front panel, select the icon, then select Image quality maintenance > Print all test plots. Interpret the printhead status plot The print consists of small dashes, one for each nozzle on each printhead. ENWW General printing advice 53

Troubleshoot print-quality issues
General printing advice
Use the following approach when you have any print-quality problem:
●
Make sure that the substrate type that you select on the front panel, and in your RIP software, is the
same as the substrate type that is loaded in the printer. Make sure that the substrate type has been
calibrated.
CAUTION:
If you have the wrong substrate type selected, you could experience poor print quality and
incorrect colors, and perhaps even damage to the printheads.
●
Make that you are using the correct media profile for your substrate, or that you have followed the
correct procedure to generate a new media profile (see
Add a new substrate
on page
41
).
●
Make sure that you are using appropriate print-quality settings in your RIP software.
●
Make sure that you are using the correct ICC profile for your substrate and print-quality settings.
●
Make sure that your environmental conditions (temperature, humidity) are in the recommended range.
See the
User's guide
.
●
Make sure that your ink cartridges have not passed their expiration dates. See

Avoid touching the substrate while printing is in progress.
Use the printhead status plot
The printhead status plot consists of patterns that are designed to highlight printhead-reliability problems. It
helps you to check the performance of the printheads that are currently installed in your printer, and to
determine whether any printhead is experiencing clogging or other problems.
Print the printhead status plot
To print the printhead status plot:
1.
Use the same substrate type that you were using when you detected a problem.
2.
Check that the selected substrate type is the same as the substrate type that is loaded into the printer.
3.
On the printer's front panel, select the
icon, then select
Image quality maintenance
>
Print all test
