5.2.5. Head Cleaning
Although your Rockhopper 38 Printer will occasionally perform an automatic cleaning
cycle, it might be necessary to manually activate a cleaning cycle.
The head cleaning function will clean both the head surface and the nozzles.
Note :
Always compare new prints with previous results. If suddenly you notice an inferior
printing quality, it is time for a cleaning cycle.
Important:
When you use your printer in a dusty environment, it may be necessary to
perform cleaning more often. Use in a dusty environment may also require a
regular maintenance check, due to dust accumulation in the printer parts. Avoid
using your Rockhopper 38 in a dusty environment.
To activate a head cleaning cycle, proceed as follows:
Step 1:
Press the cleaning key for more than two seconds without media being loaded.
Step 2:
The head is being cleaned automatically.
Note:
In case of inferior printing quality you have to perform a powerful cleaning
.
Powerful cleaning can be executed by performing the head cleaning two times; the third
time you press the Cleaning key, a powerful cleaning will be executed.
If printing quality stays poor, even after several head cleanings, refer to the
Troubleshooting part of your User’s guide.
Make sure to keep the media hold lever DOWN before pressing the head-cleaning key.
It is possible to clean the head with media loaded, however, if the media is too wrinkled,
it could touch the head. In this case, we recommend you to remove the media and
proceed with the head cleaning.
