Cautions regarding automatic conguration
Notes

Automatic conguration sets nozzle map mechanically, so absolute precision of the setting cannot be guaranteed.

The printer cannot congure correctly nozzle map in the following cases. In such cases, improve the conditions or perform
manual conguration.
- The media used makes the check via sensors impossible.
(Some media types, even conventional ones, may not be supported by automatic conguration.)
<Examples>
- Transparent media
- Media with a rough surface
- Media with an extremely high or low degree of reection
- Media on which the pattern cannot be printed properly, such as when the ink tends to bleed
- Media where density dierences do not appear on the printed pattern.
- Media that does not advance smoothly
- Media that wrinkles easily
- The media surface is soiled with dust, ink, nger marks, etc.
- A gap tends to form between the platen and the media
- Lots of nozzles are clogged
- The media heater temperatures are not suitable
- The environmental luminosity is too strong
- The bidirectional or media advance adjustment value is not set correctly

With automatic conguration, the printed pattern is read automatically. However, discrepancies may appears in the printed
pattern between media lots or if the media is old. Therefore, the detection results may be incorrect even when using the
same media.
In such cases, use manual print adjustment.

Depending on the environment temperature and humidity, nozzles may clog after automatic conguration, even if it
happens rarely.
In such a case, rst perform cleaning to recover the nozzles, and then perform manual conguration.
