HP LaserJet P3015DN
I’ve been working on a P3015dn for an account for the last couple weeks, it has been giving a jam error but there will not be any paper pulled up. It will happen larger print jobs about 4 to 5 sheets in. I will hear the tray 2 solenoid click three times before it errors out, I have replaced the pick up roller and even checked to see if the solenoid is sticking at all and its not. The new feed roller only helped for a couple days and is still in new condition. I am thinking of trying another tray, but was wondering if there was anything else I should try.

Dust, dirt, or debris: Not cleaning the HP Printer can also result in a paper jam error. So, if you find that no paper is stuck but a paper jam error showing, you must check for the dirt or dust on the device.
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.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.
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.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
If your printer has a paper path cover behind the carriage, remove the cover, and then remove any jammed paper. Pull out the input tray, and then remove any jammed paper. If your printer has a bottom cleanout door, carefully lift the printer and look under it, and then remove any jammed paper from the bottom cleanout.
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 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.
One sensor is located in the printer carriage. A second sensor—the Auto Sense sensor—is located in the back of the printer near the paper `clean out` area. Each sensor performs a specific set of media detection functions.
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.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
If you have not installed a drum unit or have installed the drum unit improperly, then this may cause a paper jam in your Brother machine. If the error message remains, open and close the front cover and fuser cover firmly to reset the machine.
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.
Dots are typically caused by foreign material inside the machine (for example paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages.
Use isopropyl alcohol or ethanol according to the manufacturer`s safety guidelines, as applicable. Wipe the roller with a lint-free cloth dipped in isopropyl alcohol or ethanol. After cleaning the roller, make sure that no lint or other material remains on the roller.
Among the more common technical issues that may bring down a printer are disconnected cables, malfunctioning routers, and low ink levels. Moreover, software problems such as interrupted connections or incorrect settings in your system`s drivers can also cause your printer to show up as offline.
The Cache Manager stores the cache files, by default, in c:\program files\printer properties pro\printer installer client\cache.
The most common signs include the following. The paper starts to feed into the printer, then stops. You may hear a crumpling sound as the paper gets stuck and crumpled up inside the printer or paper tray.
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.
HP printhead lifespans can vary significantly. We`ve seen a printhead that prints 40,000 pages and have also seen some print only 2,000 or less. The HP`s one-time use cartridge should last at least ten refills, but it sometimes fails before that.
Restoring the factory-set defaults returns most of the settings to the factory defaults. It will not reset the page count, tray size, or language.

Paper Jam error but no paper jam
ANSWER : Obviously you didn’t get all the paper cleared out. There is a small scrap in the paper path causing the jam when the paper hits it. You can try clearing it out by inserting something stiff like a piece of file folder from the back of the printer into the paper path and pushing the offending piece out that way.
