Example 7: Jam code J042 or J090 appears when printing is performed on one side to deliver the paper with its printed side face down

PreviousNext

When printing is performed on one side to deliver the paper with its printed side face down, the paper is bent at corners when it is turned over. This problem occurs when thin paper of 52.3-80 g/m² is used. Paper bent at corners will be delivered.

Decurling method

Perform "Decurling Type 1" in Table 1 to deliver the paper along the switch back guide plate.

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.
