HP has determined that 99% of all lines and streaks on copies made by feeding the original documents through the ADF are caused by debris on the ADF glass. Debris can include dust, paper or toner dust, residue from sticky note adhesive, correction fluid or tape, ink, fingerprints, and more.
Look for jammed paper or debris inside the printer, and then use both hands to remove any that you find. Use both hands to remove any jammed paper or objects from the input bin. Align the cartridge with the tracks inside the printer, push in until firmly seated, and then close the toner access door.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
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.
Change mode in printer settings

Open the Control Panel and then the Devices and Printers option. Find your printer in the Devices and Printers window and right-click the icon with your mouse. In the menu that appears, select Printing Preferences and find the option for Orientation in the preferences window.

This error can sometimes occur even when you`re not trying to print, or if you don`t have a printer installed. To overcome this issue, the first thing to check is to make sure you have the latest printer driver installed for your printer.
Generally speaking, a visible vertical line down your page after printing is an indication that the image drum in the machine may be damaged. It could also mean that the machine is reaching the end of its life.
Paper curl is caused by an excess amount of moisture in the paper. The first step to ensure less paper curl is to store your paper in a cool, dry area. By doing so, you will reduce the amount of moisture and humidity the paper is exposed to. The next step is to always fan the paper before placing in the machine.
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.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
Well, it`s a very small increase in filament used, but if you plan to print the same object numerous times, this can quickly add up. As a general rule, printing vertically reduces the total financial cost and increases the quality of any items that you print, however, it does take a longer time to create each one.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.

P4015 P4515 Noise Problems
ANSWER : I have a 4015 that has optional tray3, and optional tray4-1500 sheet stacker. The noise goes away if I remove the optional trays, and run printer by itself. When I add back either tray the noise comes back. from what I have read the tray1 electromagnetic clutch assembly drives the optional trays when they are installed.
