The error to indicate wrong pressure such as [NEGATIVE PRESSURE] and [POSITIVE PRESSURE] appeared.

  • Please see the following.

If the printer is operated in wrong environment or deteriorating with age, the pressure managed by the printer exceeds the limit and the error message related to pressure such as [NEGATIVE PRESSURE](wrong negative pressure) or [POSITIVE PRESSURE](wrong positive pressure) appears.
Note that the warning message [Negative P. ADJUST] appears when you need to work on pressure adjustment; this is not caused by wrong pressure that exceeds the limit.

When the error message or warning message appears to indicate wrong pressure, see [If negative pressure abnormality occurs] in the operation manual (UJV500, JFX500) to work on the pressure adjustment.

Please work on the pressure adjustment once a week as a pre-emptive solution.
