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.
When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
What`s happening is that the drum or rollers could have a fingerprint or dirt that is smudging the toner on the page as it passes through to the fuser. It is normally caused by the rollers. If the marks are always in different places, then it`s most likely to be the drum.
If your printer is running low on ink, it may start printing blank pages. To check your ink levels, go to your printer`s control panel and select the Ink Levels option. Whenever the ink levels are low, replace the cartridges with new ones. You can also try shaking the cartridge gently to redistribute the ink.
Check the ink levels

Sometimes, the printer may not print black ink because it is low or empty. You can check the ink levels on the printer`s display, or by using the software that came with your printer. If the ink level is low, replace the cartridge or refill it according to the manufacturer`s instructions.

For laser printers, the issue could most likely be due to a low toner, which means it`s time to change the toner. If you don`t have a toner cartridge handy, you can extend the life of the current cartridge that you`re using by removing the toner from the printer and slowly tipping the cartridge from side to side.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
Paper Jams

This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.

Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
The message `Fuser Error` or `Self-Diagnostic` means either the fuser has reached the maximum temperature allowed or there has been an error in detection of the correct temperature during specific times of the printing process.
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.
In order to resolve this issue when printing PDF documents you need to switch on an option called “Print as Image”​within you Adobe software.

HP Color Laserjet blank pages – only jetdirect page
ANSWER : What about the engine test? To do that, drop down the front tray. Feel around on the left side at the top and you’ll feel a little plastic dongle. If you lift up on that it will initiate an engine test page. That will be a page containing lines of each color.

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.
