The line printed by the nozzle 159
(indicated with the arrow) is bent to
the nozzle 161.
=> The nozzle 159 prints bent lines.
If the spaces between
the lines are even, no line
is bent.
If there are uneven
spaces between lines,
some lines may be bent.
If pint defects are found on the nozzle print, perform (5) Print head cleaning [NORMAL] again. If print defects
still occur after several print head cleanings, perform settings for NOZZLE MAP
Note
- Do not expose the print heads for an unnecessarily long time when taking them out of the capping unit.
Finish the work quickly and cap the print heads.
Nozzle map (smart nozzle mapping) is a function used to prevent print quality degradation when an identified
nozzle is blocked. Generally, when only one nozzle is blocked, the print quality is not affected. However, when 2, 3
or more nozzles are blocked, the print quality is affected and the expected results may not be obtained. The smart
nozzle mapping function compensates the print defects due to a blocked nozzle by using another nozzle. Contact
a service representative is you are not able to compensate all print defects using this function.
