HP DesignJet T730 / T830 Printhead Error Codes (0027 Series) – What They Mean and How to Fix Them
HP DesignJet T730/T830 Printhead Error Code Fix – Orange County Repair Experts.HP DesignJet T730 and T830 are popular large-format printers used by architects, engineers, and construction professionals. While they’re known for reliability, printhead issues can still occur—often displayed as system error codes starting with 0027-XXXX.
In this blog, we break down what these 27.00 Printhead (PHA) error codes mean, why they appear, and how you can resolve or diagnose them.
What is a PHA Error on HP DesignJet?
“PHA” stands for Printhead Assembly. It includes the printhead electronics, sensors, heating elements, and communication circuits. When the printer detects an issue within this system, it triggers a 0027 error code.
Common 0027 Printhead Error Codes & What They Mean
Here are the most frequent error codes you may encounter on your HP DesignJet T730 or T830:
| Error Code | Description |
|---|---|
| 0027-0001 | Generic PHA error – general communication or initialization problem |
| 0027-0002 | Printhead not responding – may indicate a faulty or unrecognized printhead |
| 0027-0006 | Unrecognized pen type – possibly due to a third-party or incompatible printhead |
| 0027-0012 / 0013 | Temperature out of range – sensor failure or extreme environmental conditions |
| 0027-0016 | Pen not heating – heating element or power delivery failure |
| 0027-0020 to 0032 | VPP/VDD voltage errors – issues with printhead power regulation |
| 0027-0059 | Missing printhead – the system can’t detect a printhead in the carriage |
| 0027-0060 | Wrong part – incompatible or non-genuine HP printhead installed |
| 0027-0067 | Fake PHA change – printhead detected as counterfeit or tampered with |
What Causes These Errors?
Some of the most common causes of printhead (PHA) error codes include:
Faulty or worn-out printhead
Loose printhead connections or damaged ribbon cables
Ink leakage or contamination inside the carriage area
Extreme heat, cold, or humidity
Power surges or firmware glitches
Use of non-genuine HP supplies or remanufactured printheads
How to Troubleshoot or Fix These Errors
Power Cycle the Printer
Turn off the printer, unplug it for 2 minutes, then power it back on.
Inspect the Printhead
Open the printhead area, remove and reseat the printhead carefully.
Check for ink spills or visible damage.
Check for Firmware Updates
Install the latest firmware from HP’s support site to fix known bugs.
Use Genuine HP Supplies
Non-OEM cartridges or heads can trigger authentication errors (like 0027-0060 or 0067).
Replace the Printhead
If the error persists, the printhead may be defective and require replacement.
Call a Certified HP Technician
If voltage or temperature-related codes keep appearing (e.g., 0027-0016, 0027-0021, 0027-0053), professional diagnostics are recommended.
