HP DesignJet Error Codes
The HP DesignJet error code displayed on your large format (wide format) printer — e.g. 79:04 — does not always provide an exact indication of the problem or issue. You (the user) will often be unable to diagnose or fully resolve the DesignJet fault yourself — even with the error code information provided here.
HP DesignJet error codes are not an exact science. They exist to help the engineer diagnose key areas for assessment, and can often indicate one or more parts have failed. This is where it pays to engage an HP Authorized DesignJet repair technician so that you receive the fastest and most cost effective fix. Based upon the reported fault, a trained and qualified HP DesignJet technician will usually work through a predefined set of tests and apply many years of working knowledge to affect the fastest repair — choosing those parts first which he knows will usually resolve the fault rather than systematically working through the manual.

Special Note: Tips to help your HP DesignJet and DesignJet XL stay healthy during the COVID-19 pandemic
You may need to leave your office for a long period of time during this event and here are some tips and tricks on keeping your office asset healthy until it's back to business as usual:
- If you plan to leave your HP DesignJet or DesignJet XL Printer for a more than two weeks, it's best to leave it on. All HP DesignJet and DesignJet XL Printers are made to enter sleep mode when not in use after a certain period of time. This sleep mode is designed to conserve power, reduce mechanical wear, and keep the ink system from drying up. Every 24 hours your printer will wake up and check the printheads to ensure that they are operational and then go back to sleep. There are stories of printers in sleep mode for over 6 months waking up when a job is sent to it, and printing like a fine-tuned machine. It will consume a small amount of ink to keep the ink system fresh, but it is a tiny fraction of the price to replace just one printhead.
- If the printer does need to be powered off for any reason: Keep the ink cartridges in place, unload the paper, and make sure to power off via the power button / front panel, to make sure that the ink system has been properly parked in place.
When you do get back to printing, here are some tips to keep the HP DesignJet and DesignJet XL in top shape
- Run the printhead cleaning from the front panel before your first print run or if you see white banding or a "replace printhead" messages. If the printer has been idle for a while, you might need to run this procedure 2-4 times to clear the white banding. If you see no improvements, then it's unrecoverable and it will be time to replace the printhead.
- Later HP DesignJet and DesignJet XL models have made it convenient with a touch of a button on the front panel to do the 4 most common calibrations and in proper order. Make sure to have the paper you plan to use loaded as it will be needed for some of the calibrations. These calibrations are done automatically, so you can do other things while the printer optimizes itself.
These details and more great information about this can be found in your DesignJet's User's Guide under "Move or store the printer".
