Answer: If you operate the printer without removing the static, it will cause defective printing or machine failure.

[Detail]:
1. Problems caused by Static:

– Droplets fired from print head are placed to wrong spots, resulting in blur printing.

– Ink mist may adhere to crucial components, giving the printer significant damages.

– Adhesion of mist to Print head may cause “nozzle clogging” or “nozzle deflection”, giving you
　higher chance to replace the Print head.

– If ink mist adheres to the bottom side of carriage, “ink dripping” on the surface of media may
　be caused during the print.
2. This is how you remove static:

– You can reduce static on the surface of media by attaching static eliminator to the unit.
　Product name: Ionizer Kit (Product code: OPT-J0342)
　Please see the details in “Q: What kind of optional unit is available?”

– Increase the room humidity and check the outcome.
　*Set the humidity to the range of 35～65％Rh, as stated in the machine specification.

– Make sure that your printer has ground connection.
　*Bring your electrical worker to check the connection.

– If you wipe the surface of media with a cloth soaked with rubbing alcohol, it will
　reduce the static. But the wiper trace may come out after printing.

　*Also noted that if you install the printer on carpeted floor, it may accumulate static.
