Paper Jams

This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.

There are a few things that could be the cause of this problem, including: Empty ink or toner cartridges that need replacing. Ink or toner cartridges that have become dislodged from their proper place. The wrong paper size loaded in the input tray.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.

ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid.
