- If foreign objects on the nozzle surface are the cause, powerful maintenance with Maintenance Liquid 16 may resolve firing issues.
[Important]
When performing powerful maintenance using Maintenance Liquid 16 for the first time,
please consult our engineers for the procedure in advance.
* The powerful maintenance may not resolve all firing issues.
Firing issues caused by factors other than foreign objects on the nozzle surface may not be resolved.
[Precautions]
Please be sure to confirm in advance.
How to perform powerful maintenance
<Step 1>
Use Maintenance Liquid 16 to perform nozzle wash.
(1) On the LOCAL mode screen, select [FUNC1] (MEMU) > [MAINTENANCE]
> [Station] > [Nozzle Wash].
(2) Clean the wiper nozzle and around the wiper using the maintenance liquid for daily maintenance
(Maintenance Liquid 16 cannot be used) and press the [ENTER] key.
(3) Fill the cap of the area where the issue is occurring with Maintenance Liquid 16.
- Amount to use: Fill the cap until it's full (approx. 3 cc, equivalent to 1.5 syringe doses).
- Be careful not to spill the Maintenance liquid 16 from the cap.
(4) Press Up/Down key to set the waiting time to 10 minutes, then press the [ENTER] key.
- If you cannot set the waiting time on your product, please contact our call center for a version
upgrade that requires an on-site visit.
After nozzle cleaning is completed, please proceed to the next step 2 immediately without delay.
