Rebuilding Optional 500 Sheet Paper Feeder P/N Q2440B for the Hewlett Packard 4200, 4300 4240, 4250 and 4350 Printer Series
Q2440B

The Paper feed solenoid at some point will need to be replaced because of Jamming issues. You will experience 13.98, 13.02, 13.03 errors. Look at the error log in diagnostics menu. I test the solenoid by using the paper path test and run 10 single sided prints and pay attention to the timing of the prints coming out. If the solenoid is bad you will notice it begin to pause or I liken it to burping. If it’s real bad it will just jam and you will get the errors listed. Some of you will opt to buy a new unit from EBAY but I’ll warn you that buying a used one leaves you with the same problem. I recommend buying a new one or rebuilding your existing unit.
