When printing on side 2 for duplex printing, due to upward curling, paper may be caught at the upper part of the fusing unit, causing a paper jam.
Upward creases or other damage remains on the paper.
Decurling method
Because this problem occurs while printing is performed, paper needs to be decurled before printing on side 2.
Perform "Decurling Type 1" in Table 1 on side 1.
By decurling side 1 of the paper upward, you can print on side 2 with the paper decurled downward.
Decurling for jam codes J036 and J086 is effective for duplex printing only. This type of decurling is not effective for single-sided printing.
In the 03: [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Skilled Operators] menu, select 0301: [Adjust Paper Curl].
Select [The paper tray' name (1 Sided)].
For example, to decurl the paper fed from Tray 1, select [Tray 1 (1 Sided)].
Select [Adjust 
Curl: Weak], [Adjust Curl: Medium], or [Adjust Curl: Strong].
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.
