In my opinion, the HP OfficeJet Pro X451DN is a very reliable printer. Why do I feel that way? Well, over the years, I have only had to replace depleted ink cartridges for clients and on one occasion, solve a paper jam issue.
Loading and Unloading Ink Cartridges
The first time I had to replace an ink cartridge for a client, it took around two minutes to figure out how to do so. It wasn’t until they brought the replacement ink cartridge out of their storage closet that I saw how small it was and that it would be front-loaded. Before loading, I wrote the date on the ink cartridge so that we would have an idea of how long it lasted. This would ensure that backups were not bought too early so that they would go bad.
I rarely get a call to fix a paper jam issue since I show the proper way to load paper in the trays. If you need help to find and stop a paper jam on an HP OfficeJet Pro X451DN, see my quick solution.
I find that when the HP OfficeJet Pro X451DN refuses to print, it is due to ink capacity so check the display. If you press the power button and it turns red and the printer is still not showing anything on the display, immediately unplug it from the power source for a few seconds. After returning power, watch the display and correct any further issues. Once corrected, any pending jobs will automatically print. You can tell this as the flap will lift so the paper can exit. Please note that it may take up to two minutes to retrieve the printout as the printer needs to warm up again.
