Test Printing

You can perform printer status printing using the self-test to check if any print errors, such as dot drop-outs, are
occurring.
You can use the nozzle check pattern which is printed to check whether the nozzle is clogged.
Follow the procedure below to perform the self-test.
1
Make sure the printer is turned off.
2
Turn the power on while pressing the Feed Button. Continue holding the Feed Button
until the printer begins feeding roll paper.
The printer status is printed on the roll paper.
3
Check the printed nozzle check pattern.
If the pattern is printed normally, all the lines are printed properly as shown in the left figure below.
Perform head cleaning if there are any broken or unprinted lines due to nozzle clogging, as shown in the right
figure below.
