Example 4: Jam code J031 appears when duplex printing is performed (downward
curling)
When printing on side 2 for duplex printing, due to downward curling, paper is caught at the paper
transfer belt, causing a paper jam.
Decurling method
Because this problem occurs while printing, the paper needs to be decurled before printing on side
2.
Perform "Decurling Type 1" in Table 1 on side 2.
By decurling side 1 of the paper downward, you can print on side 2 with the paper decurled
upward.
• Decurling for jam codes J031 is effective for duplex printing only. This type of decurling is not
effective for single-sided printing.

2. Select [The paper tray' name (1 Sided)].
For example, to decurl the paper fed from Tray 1, select [Tray 1 (1 Sided)].
3. Select [Adjust
Select the degree of decurling from "Weak", "Medium", and "Strong" according to the degree of
curling. If you cannot assess the degree of curling, try decurling in the order of "Weak", "Medium",
and "Strong". Decurling more than necessary may cause a paper jam, scratches, or sheets being
bent at corners.
