The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image forming apparatus comprising:
an image forming section configured to form an image on a sheet;
a pair of rollers disposed on an upstream side of the image forming section in a sheet conveyance direction, the rollers being configured to convey the sheet to the image forming section;
a displacement detection section configured to detect a lateral position of the sheet passing between the rollers;
a displacement correction section configured to translate the rollers in a lateral direction of the sheet, and reset the lateral position of the sheet to a reference position;
a translation amount determination section configured to determine a translation amount of the sheet during a displacement correction performed by the displacement correction section; and
a control section configured to refer to a translation control table in which a required translation amount for resetting the sheet to the reference position and a translation command value for operating the displacement correction section to translate the sheet by the required translation amount are associated with each other, operate the displacement correction section in accordance with a translation command value corresponding to a detection result obtained by the displacement detection section, obtain at a predetermined timing a relationship between the translation command value and a translation amount of the sheet, and update the translation control table on the basis of the relationship, wherein
when updating the translation control table, the control section determines whether a displacement of a sheet in a certain range is correctable by the update of the translation control table, and
the control section updates the translation control table when the displacement of the sheet is correctable, but does not update the translation control table when the displacement of the sheet is not correctable.
2. The image forming apparatus according to claim 1, wherein the control section sets a threshold value corresponding to a certain translation command value, and compares the threshold value with a registration amount of a sheet which is translated by the certain translation command value to determine whether the displacement of the sheet in the certain range is correctable.
3. The image forming apparatus according to claim 2, wherein the certain translation command value is an upper limit value or a lower limit value of a translation range of the displacement correction section.
4. The image forming apparatus according to claim 2, wherein the control section compares the threshold value with an average value of translation amounts of a plurality of sheets which are translated by the certain translation command value.
5. The image forming apparatus according to claim 1, wherein, when the displacement of the sheet in the certain range is not correctable, the control section provides a notification that requests replacement of components of the displacement correction section.
6. The image forming apparatus according to claim 1, wherein, when the displacement of the sheet in the certain range is not correctable, the control section prohibits an image forming operation for the sheet.
7. The image forming apparatus according to claim 6, wherein, on the basis of a user operation, the control section withdraws the prohibition against the image forming operation for the sheet.
