How to Solve The 13.A2.FF Paper Jam error at power up HP M601 M602 M603 M604 M605 M606
There has been a upgrade to the printer's tray 1 pick up assemblies for the P4015 series and M600 series which allow you to pull down an access cover to inspect the flag for any obstruction.
To gain access to this area, the printer's tray 1 pick up assembly must be completely removed, then check to verify functionality of the feed flag and to see any hidden debris.
If the flag operates correctly, you may try to take compressed air to the sensor itself to clear any obstruction. If that does not clear the error message, the entire printer transfer guide assembly should need to be replaced.
