Not sure but I think this model has a separate drum unit try replacing the drum unit if this still doesn't work then the laser unit has a fault also you could try vacuuming out the inside of the machine as maybe caused by loose toner on the contacts.

Thanks J

Try to print clean page ,
Print a cleaning page During the printing process, paper, toner, and dust particles can accumulate inside the printer and can cause print quality issues such as toner specks or spatter, smears, streaks, lines or repeating marks. Follow these steps to clean the printer's paper path.
  1. Load copier-grade paper (not bond, heavy, or rough paper).
  2. On the printer's control panel, touch the Menu button.
  3. Touch Configure Device .
  4. Touch Print Quality .
  5. Touch Process Cleaning Page .
A Cleaning message appears on the printer control panel display while the cleaning is taking place. The cleaning process takes a few minutes to complete. Do not turn the printer off until the cleaning process has finished. A page will be printed when the task is complete. Discard the page. You might need to repeat the cleaning process to thoroughly clean the printer. Print a few more pages to see if the problem is resolved.

It prints a complete black page, without any images or text. Even at the test page!!!. Any idea as to what can be done?

I think the ribbon or printer head need to be change since it prints a complete black page, if it is a blank page it prints, i would have said the toner ink is low in the cartridge or finished but since it is a black page it needs replacement.

I suggest you get a technician to help fix it.

I wish you best of luck

I changed the black toner cartidge for the first time and immediately got a multicolored stripe all the way across from top to bottom on the middle of the right side of the page. I replaced the toner

Vertical streaks or bands appear on the page.

One or more print cartridges might be low or defective. If you are using non-HP print cartridges, no messages appear on the device control panel or in the HP Toolbox. Replace any low print cartridges
Marks repeatedly appear at even intervals on the unprinted side of the page.

Internal parts might have toner on them. The problem typically corrects itself after a few more pages. The paper path might need cleaning. Clean the device. The fuser might be damaged or dirty. Clean using instructions in HP Toolbox.

Dell 3110 toner cartridges spray toner all over the page

The toner cartridges are not being completely locked in the printer and/or are misseated. When locking the cartridges, ensure the arrow is completely moved to the closed lock icon on the right side of the cartridge.

When we print manually the whole page comes out completly black.

Try replacing the toner cartridge first, then proceed with the other items.
Thank you and let me know what happens:
Binary Bob

How common*

DC Controller PCA is defective. If the DC Controller turns on the laser beam continuously,
the entire surface of the Photosensitive drum is neutralized causing a completely black page
Replace the DC Controller PCA

Defective toner cartridge
Replace the toner cartridge

High voltage contact springs are dirty or defective. The high voltage contacts are mounted on
the High Voltage Power Supply PCA and protrude into the toner cartridge cavity
Inspect and clean the high voltage contacts. If damaged, replace the High Voltage Power Supply PCA.

High voltage power supply circuit is defective (not supplying the correct negative voltage)
Replace the High Voltage Power Supply PCA
some printers have the high voltage power supply on the DC controller.

Laser/Scanner Assembly is faulty (turning laser on continuously)
Replace the Laser/Scanner Assembly

Light is leaking into the printer
Make sure that all covers are in place
possible, but not likely
