HP DesignJet 0001-0001 Error
HP's T730/T830 front-panel reference lists 0001-0001 as a system error whose published first action is to restart the printer.
What this code means
This is a system-level front-panel error for the DesignJet T730/T830 family. HP's user-level first step is a normal restart rather than opening the printer or replacing parts.
Affected models / family scope
- DesignJet T730
- DesignJet T830
- DesignJet T830 MFP
Common formatting
- 0001-0001
- 00010001
- 0001 0001
What to try
Restart the printer normally.
Let current activity stop, use the normal power control, and allow the DesignJet to shut down and start back up.
Wait for initialization to finish.
Do not resend the failed job while the printer is still booting or calibrating.
Retry one simple job.
If the printer returns to Ready, send a small test before retrying the original document.
Record useful context if it returns.
Write down 0001-0001 and the current firmware version before contacting support.
When to stop and get help
If 0001-0001 repeatedly returns after a normal restart, use HP support/service. Repeated power cycling is not a substitute for diagnosing a persistent system error.
