The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
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.
Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.
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.
Common causes include dust and grime, worn rollers, or inappropriately weighted paper. Prevent paper jams by regularly cleaning your printer and replacing parts as needed. Check the weight of paper that your printer is rated for as well. The printed product is faded.
There are numerous possible causes for a printer that`s randomly producing blanks. The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.
If you`ve checked your ink cartridges and they still have enough ink to print, chances are that your printer might still randomly produce blanks. Some of the reasons why you still get blank printouts include: Congested nozzles. Improper cartridge installation.
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
Several factors may cause the product to print blank pages, such as print settings, low ink, or the product itself. Check the following: Make sure the product is placed on a flat, stable surface that extends beyond the base in all directions. The product won`t operate properly if it`s tilted or at an angle.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.
