Quick answers: the most common HP DesignJet T250, T650 and Studio errors
Restart the printer first: switch it off, unplug it for a minute, then switch it on. If the code comes back, try the first fix below.
| Error code | What it means | What to do first |
|---|---|---|
| 0942-0188 | Carriage cannot find its home position. | Restart, clean the encoder strip, and check for paper blocking the carriage or service station. |
| 0021-0017 | Service station cannot move all the way. | Switch off, open the printhead door and remove any paper blocking the service station. |
| 0042-0117 | Carriage cannot move (carriage jam). | Restart, check the carriage path for paper or friction, and run the carriage servo test. |
| 0041-0017 | Paper motor cannot move (paper jam). | Clear the paper path, restart and run the paper servo test. |
| 0087-0001 | Encoder strip failure. | Restart. If it returns, the encoder strip needs replacing onsite. |
| 0024-1000 | Printhead start-up failed: a cartridge is missing or faulty. | Restart, check all four cartridges are seated, and try a new HP cartridge. |
| 0027-00XX | Printhead problem (any 0027 code). | Remove, clean and reseat the printhead, and check both latches are closed. |
| 0001-0082 | The clock (RTC) battery has run down. | Restart. If it returns, the battery needs replacing onsite. |
| 0153-0302 | Multi-sheet tray not detected. | Remove and refit the tray, making sure its latch is closed. |

If you are managing or servicing an HP DesignJet T250, T650, or Studio Series Plotter, encountering a system error code can bring your workflow to a halt. This guide provides the full unedited extraction of severe and silent error codes from the service manual to help you identify internal malfunctions. Often, the first step is to restart your printer to see if the error clears and to get a more accurate diagnostic.
