You need to ensure your HP printer has enough paper, ink, or toner, and it is not stuck on paper jam. Also, check the status of your printer cartridge and try replacing it with a new one if it is not good enough. In some cases, your HP printer stops printing after you replace its parts.
Printers may produce poor quality printing if they are exposed to too much heat. Don`t place your printers in a high-temperature area or near other devices that produce excess heat. In addition, keep them away from windows, where heat and humidity can be high.
This can be caused by loose cable connections or an outdated printer driver or operating system. The HP Smart app (below) can automatically diagnose and resolve printer offline issues in Windows operating systems.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Reasons why your HP printer has ink but won`t print
This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
Some of the most common printer problems that most of us have experienced include paper jamming, slow printing, uneven printing, and wrong colour output. If you use your printer frequently, we know how annoying it can be to have persisting problems with the printer.
Press and hold the printer`s power button for 15 seconds. The printer should be directly connected to the wall outlet and not to a surge protector. Reconnect the power cable to print and the printer should power ON by itself. If the printer doesn`t power ON then please manually power it ON.
This means the printer is starved of the data it needs to keep printing. Some printers will pause and keep trying, for a little while, but many will just give up at this point and spit out your half printed page. So – the moral of the story is really to always use a wired connection if at all possible.
Smears and smudges on the paper can be caused by dirt, dust, or toner accumulated on the rollers or transfer belt as it passes through the paper. Cleaning your printer, particularly the rollers, is one of the options for removing black markings from paper.
If your HP printer not printing black ink correctly, here`s what you should do. Using non-genuine ink cartridges. Printheads that have become clogged. Ink cartridges that are defective or empty.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
A paper jam is when paper or other printed material gets stuck or lodged in a printer and cannot eject.
If your printer is spitting out pages full of strange characters, symbols, or strange formatting, your inkjet printer drivers may be outdated, incompatible with your operating system or corrupt. Drivers are important to the proper function of your inkjet printer and it is best to check for updates regularly.
To resolve most print quality issues, use genuine HP cartridges, and in some cases, you might need to allow the printer to complete the automatic servicing routine. Check the paper and print settings to make sure that they are correct for the print job, and clean the cartridges and printhead.
