Automatically Checking and Cleaning the Print Head

The printer automatically checks the nozzles and cleans them if necessary. You can specify how often you want this to happen or turn this feature off. You can also have a nozzle check pattern printed on a regular basis, so you can check it yourself.

1. Press r Menu. PRINTER SETUP is selected. Press r again.

2. Press d until AUTO NOZZLE CHECK is selected, then press r.

3. Select one of the following, then press OK:

• ON: PERIODICALLY—The printer periodically checks its nozzles and runs a cleaning cycle if necessary (default).

• ON: EVERY JOB—The printer automatically checks its nozzles and runs a cleaning cycle if necessary before each print job. This process uses a very small amount of ink (and no paper) and is recommended if you are running large print jobs unattended.

• OFF—The printer will not perform automatic nozzle checks and cleaning cycles.

4. Press l, then select PRINT NOZZLE PATTERN and press r.

5. Select ON: EVERY PAGE to have the nozzle check pattern printed before each print job, or ON: EVERY 10 PAGES or OFF. These settings take effect only when you print on roll paper.

6. Press OK to save the setting.
