NOTE: Some of these subsystems may be available only to service engineers, because they require specific
knowledge or for safety reasons.
NOTE: In any case we recommend running the Safety Interlocks diagnostic to ensure that printing is not
disabled by a safety interlock.
Update the Print Care software
While the printer is connected to the Internet, Print Care checks periodically for updates. An alert will pop up
if an update is available. When this happens, follow the instructions to update the software.
NOTE: This update applies only to the Print Care software engine. The maintenance wizards and other
content are accessed directly in the cloud every time they are needed. Therefore, they are automatically
updated as soon as the content in the cloud is updated.
Reinstall the Print Care software
If Print Care needs to be reinstalled, please contact your service representative.
NOTE: Print Care needs to be reinstalled whenever the printer changes ownership.
