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.
Spot Colour Printing: The Advantages

Colours are more accurate because you have already determined the colour by its specific Pantone number. As the ink isn`t being mixed, the colour never changes from one print run to the next. Spot colour printing is generally more economical if fewer colours are used.

Photos and other artwork can become discolored overtime due to sun exposure, but also because of acid in the printing, framing and storage materials. This discoloration often takes on a yellow or brown look synonymous with “old” photos.
Blotchy or Streaked Printing

This can lead to blotchy or streaky printing as the toner is not properly distributed within the toner cartridge. The simple way to fix this is to remove the toner cartridge from the printer and rock it gently from side to side. Don`t shake it vigorously as this could damage your cartridge.

The most obvious sign of low toner cartridge is poor print quality. Streaking, lines or missed prints are all possible signs that cartridge replacement is imminent. If you have tried rocking the toner cartridge and are still getting poor prints, it is likely time to replace your cartridge.
Many HP printers display ink and toner levels on the control panel. Look for an Ink drop icon ( or ), a Cartridge icon , an Ink Levels menu, or a Toner Level indicator.
On your computer, in the Windows Notification Area (bottom-right corner of your Windows desktop), right-click the printer icon. In the printer menu, select the Properties or Preferences option.

Dirt, dust, or toner accumulated on the rollers or transfer belt can cause smears and smudges on the paper as it goes through the paper. Cleaning your printer, especially its rollers, is one of the possible solutions to fix black marks on paper.
To keep your printer`s ink from smearing on your labels, be sure to always use inkjet products with an inkjet printer and laser products with a laser printer. Some of our glossy products take a minute to dry, so please wait before you touch the printing.
CMYK (also known as process or four-color) printing involves tiny halftone dots of color (Cyan, Magenta, Yellow and Black) being laid onto a substrate in combinations and formations that fools the human eye into perceiving continuous color.
Spot Colour Printing uses a single (different) ink for each colour used (making it extremely precise), whereas the CMYK method uses only four colours: cyan, magenta, yellow and black (which can be mixed to create an almost infinite number of colours and shades, in just one printing press pass.

A Bad Toner Cartridge

Usually associated with compatible or re-filled cartridges, a leaky cartridge deposits toner inside your printer and onto your paper in places that it`s not intended, resulting in black spots.

If the paper is too thick, glossy or not designed for laser printing, ghosting will most likely occur. Dust and debris inside the printer can also cause ghosting as too much dirt can interfere with the drum units, transfer units and fuser units.

Lexmark paper feed problems
ANSWER : On my X204n Lexmark laser printer, it was doing the same thing you described – basically sounded like it was trying to pick up the paper from the tray and then failing after several seconds. When you’d open the paper tray, the paper looked like it had been partially taken up with some black scuff marks on the paper that lined up with the rollers that take up the paper. I inspected the rollers and although they looked a bit smooth and worn, didn’t seem like they should be a problem. However, this particular model has just a rubber tire almost like a car tire – the rubber can come off the hard plastic wheel on the inner portion. So I popped off the two rubber “tires”, turned them inside out and put them back on. When turned inside out, the rubber looked nice and … rubbery and had a lot more grippy feeling to them. The very first printing attempt after that and the paper sucked up perfectly with no problems. I think the problem is solved! So if you have similar “tires” that take up the paper, try flipping them and see if it works for you too.

Lexmark X466 empty tray
ANSWER : The “Load Tray 1 with A4 paper” means the printer is looking for A4 size paper in Tray 1 and that is not what it is detecting. You need to make sure that the paper size that is in the tray matches what the printer is expecting so it understands that it should be looking for a specific size of paper. If you are printing on regular Letter size paper – set the printer tray to Letter instead of A4 and message should go away.
