q Periodic Maintenance
Confirm that all nozzles are operating correctly. If print 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
(
P.3-53[(1) Nozzle print]
)
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.
