问题：Troubleshooting a false paper out error.
The form has black writing on the back side of the form.
The paper out sensor on the P7000 series printer is an optical sensor. If you are printing a pre-printed form that has writing on the back (think similar to a car rental contract) it will interfere with the paper out sensor, and cause a false paper out front panel error.
The solution is to order the ‘Black Back Sensor’ kit (part number 170172-001) from Printronix. This kit contains a replacement paper out sensor that accepts black back forms, as well as plain paper.
