HP 6L would not pick paper.

The common reasons for this issue are various, for instance, the paper input tray is overloaded, dust or moisture can affect the paper feed or paper pick rollers, the printer driver is old, etc. Thus, the printer cannot detect the paper that has been inserted into the tray.

Most likely the pickup roller is worn. You cantry cleaning with warm soapy water and try. If that does not work then the roller needs to be replaced.

Remove the stack of paper from the tray. Check for obstructions inside the tray. Use a flashlight to view the mechanism inside the tray to make sure that nothing blocks the paper from engaging with the rollers. Even small pieces of paper can cause paper feed issues.

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.

Slide the paper all the way into the printer. The leading edge of the paper will stop at the Paper Drive Roller. Locate the Paper Sensor/OOPs sensor on the right side of the paper path. It can be seen from the top of the printer with the Top Cover open and has red, black, and blue wires attached to it.

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.

Printer rollers are the tiny rubber wheels inside your printer that move sheets of paper through the printer. The roller that lifts the paper from the paper tray is called the paper uptake roller.

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).
