Troubleshooting for Transport/Paper Feeding

Curled Paper
Make sure that the following SPs are set to their default values, and keep them at these values at all time.
• SP1-113-001 (Curl Correction): Keep at default value of 0 (OFF)
This is because printing productivity drops to about 65 to 80% when this SP is ON. It is not effective
in reducing curl on these models.
• SP1-115-xxx (Print Target Temp): Keep at default value.
This is because fusing offset may occur when the fusing temperature is reduced. This SP is not
effective for improving image quality on these models.
Solution:
Installing the tray heaters for the mainframe paper bank and optional paper banks. (page 119 "Anti-
Condensation Heater for Paper Feed Trays")
Initial Jam
If the error occurs periodically, do the following steps. If the result is as shown in the "Problem
