Checking and solving nozzle clogging (TEST plotting)
Make test plotting to check whether there is nozzle clogging or other plotting failures.
If the finished test pattern shows any sign of abnormal conditions, carry out the cleaning
function.
• To perform the test plot on a cut sheet media, use a media whose size is A4
or larger with placed in landscape configuration.
• When in use of a roll media, the back side of roll media will loosen after test
plotting, for the media returns to the plot original point by pressing the [RE-
MOTE] or [FUNCTION] key.
Uproll the roll media by hands before plotting, and set it tidily. The loosened
roll media will cause the inferior image quality.

1. Make sure that the menu is the LOCAL mode.
Press the [REMOTE] key and put the device back into the

2. Press the [TEST&CLEANING] key.
3. Press the [ENTER] key.
The device plots the test pattern.
