Question about Dell 1720dn Laser Printer
This is usually due to a dirty imaging drum roller (green roller below toner). Remove the toner / drum assembly, then separate the two. Now slowly rotate the imaging drum roller by hand using the gear on the side of the cartridge (Try not to not touch the drum roller with your hand, as oils from your skin may cause further problems + toner is nasty) Look for toner splotches to the left and right on the drum roller as you turn it. If you see any you can clean them off with a damp paper towel. Then reassemble the printer and hold the continue button down until you hear the printer start then release it; this will print a test page.. Hopefully that will take care of the issue. Also while you got the assembly out of the printer you can clean the glass print-head lens using a clean, dry, and lint free cloth. The print head lense is located within the recessed area in the top of the printer.
- I have seen that happen to a bunch of those printers and that is usually all it is. Let me know if that takes care of it.

Open the lid of the printer. Depending on the model, there will be two cartridges on the right, one for black and one for color.
Find the cartridge that is running low on ink. The black cartridge will be in black, the color cartridge will have a patch of color (usually green) on it.
Pull down on the black clamp that is holding the cartridge in place and slide out the used cartridge.
Open the package of the new ink cartridge. Remove the protective tape and slide the new cartridge into the printer.
Snap the black protective case back into place and close the lid.
