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.
Smears that appear in addition to otherwise well-formed output may signal toner contamination inside your LaserJet, either from a leaky cartridge or from improperly fused sheets that leave toner residue behind. Smears at the edge of the sheet that enters the printer first point to dirty paper guides.
The best way to prevent smearing is to make sure you give the ink time to dry before picking up the copy or copies. It doesn`t take long, maybe 10-15 seconds. If that doesn`t work, try changing your printer settings for a lower quality print job. You generally have a choice, Best, Normal or Draft.
Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.
The fuser melts the toner onto the paper at temperatures as high as 400 degrees so that it is unlikely to melt off the paper in the future. Laser prints smudge if your printer`s fuser operates at a lower than ideal temperature. Fuser temperatures can frequently be adjusted to solve this problem.
(smʌdʒ ) verb. If you smudge a substance such as ink, paint, or make-up that has been put on a surface, you make it less neat by touching or rubbing it. […]
Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
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.
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.
Another important consideration: since laser printers use dry toner, the ink doesn`t bleed or smear, which can be a problem with inkjet printing.
Laser printers work by using high heat to fuse powdered ink to paper. There is no bleeding effect, because laser toner does not absorb into paper.
Smudging is a technique of shading. A shading is first made on paper, then a finger or a soft material like a piece of cloth is used to smear the shading to make it smooth and well blended. In Grade 4, we will use different types of dry media such as pencils and charcoal to show the effects of light and dark.
smudgeproof (comparative more smudgeproof, superlative most smudgeproof) Resistant to smudging.
Make sure the printer platen is not dirty with ink. Unplug the machine from the AC power outlet. Lift the scanner cover until it locks securely in the open position. Clean the machine`s printer platen(1) and the area around it, wiping off any scattered ink with a soft, dry, lint-free cloth.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
