Make sure your paper meets the specifications for your product. If paper dust builds up on the rollers, they may lose traction and become unable to feed paper properly. Clean the paper guide. If roll paper does not feed, cut the end straight across and uncurl it by rolling it backward, if necessary.
The paper tray is empty or overloaded. The paper is curled. The print side, or shiny side, of the paper is not loaded in the paper tray face up. For photo paper, always load the rougher side of the paper facing down.

The paper has holes along both sides that fit over the sprockets located on the feeder wheel. When the wheel turns, it feeds the paper into the printer. The holes are torn off the paper after the printout is complete. And, yes, printers still use this type of feeder mechanism.
There are different methods of paper feeding. With dot matrix printers, paper is often feed through pins on a wheel that grab and slowly move paper through the printer. With inkjet and other page printers, paper is fed through the printer with rollers that grab and move the paper through the printer.
Dust, paper fiber, and other debris might accumulate on the pick rollers and cause paper feed issues. To help prevent paper feed issues, clean the rollers inside the printer and in the duplexer (if equipped). If the other steps in this document fail to resolve the issue, then reset the printer.
Adjust the paper guides in the tray to match the size of the paper. Remove the paper, smooth it out, then reload it. If the paper misfeeds, do not use that paper. Remove the moist paper, then replace it with new, dry paper.
The manual feed slot is located on the front of your printer. It can be closed when not in use, making the product more compact. Use the manual feed slot to print transparencies, labels, envelopes or postcards in addition to making quick runs of paper types or sizes that are not currently loaded in the paper tray.
Printer rollers are the small circular rubber pieces that help feed printer paper through your printer. Over time, they can accumulate dust from the paper and ink residue from printing double-sided pages. To clean your printer rollers, you`ll need to first locate them in your printer.
A paper feed issue can occur for several reasons, such as dusty or contaminated paper rollers, the condition of the paper in the tray, or even issues with the software. To resolve the issue, try each solution in this document, and then use the steps in this section to print a self-test report.
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.
This is often caused by the fact the pick-up roller is worn out. The layer of rubber around this plastic part overtime gets too smooth, preventing paper from feeding properly into the printer. This fix is not really hard, will take no more than half an hour and costs around 10,- (Euro or Dollar).

HP Laserjet 6MP wont feed paper
ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.

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.
