Low-quality paper leaves an accumulation of tiny paper bits often referred to as “paper dust” inside the machine. This "dust" is one of the top causes of paper jams. More dust means more jams. Besides jams, the dust also contributes to poor-quality prints and causes machine parts to wear at a faster rate.
Unplug the power cord from the wall outlet. Wait at least 15 seconds. Plug the power cord back into the wall outlet. Reconnect the power cord to the rear of the product.
your pickup roller is dirty and the printer can't grab a piece of paper. it will say paper jam when it does this. get a drop of dishsoap and clean the pickup roller of your printer with this. scrape at it with your fingernail to get the roller clean and wipe it off with a damp washcloth.
Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again. With the printer turned on, disconnect the power cord from the printer. Unplug the power cord from the power source.
Improperly Loading Paper into the Device
Loading paper that is stuck together, frayed, curled or bent can cause a jam. Overloading the paper tray, loading different thicknesses of paper in the tray or using paper that isn't appropriate for your particular printer can all result in a jammed printer.
If your printer keeps jamming, you should know that the most common cause of a jam is misalignment of the paper. Paper needs to load in smoothly, completely flush with the tray. Overfilling the tray is a great way to ensure you will be spending some personal time getting to know the inside of a printer.
The first step in any paper jam clearing process is to clear the loading tray. Remove any loose paper sitting in the tray. If you can see any paper obviously caught in the feeding mechanism, slowly and carefully remove the paper one sheet at a time.
Overfilling the paper tray is frequently causes paper jams. Many printers have sliding mechanisms that allow different types and sizes of paper to be fed into the printer. If the slider is not correctly positioned, it can cause a paper jam.
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.
The first step you should take when you think you have a clogged printer printhead is to run the automatic cleaning cycle on your printer. You may want to do this two or three times to see if it clears the clog. The automated cleaning cycle forces extra ink through the print heads to loosen any clogs or blockages.
The guides in the paper tray are there to make sure the stack of paper is exactly where the printer was designed to grab from. If the paper is even slightly askew, the rollers will pick it up a little crooked, and — guess what — the crooked sheet will immediately get jammed.
A paper jam is when paper or other printed material gets stuck or lodged in a printer and cannot eject.
If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.
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.
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.
Once properly clean, they will perform better, but to get them like new again, you should apply a restoring compound which lubricates the rollers and restores their tackiness. Oritech has a Rubber Roller Restorer that you an use on the rollers, for approximately $15, that will last you a life time.
