Dog-eared corner of the leading edge of paper due to the curl

[Symptom]
A corner of the leading edge of paper may be folded down due to the curled paper of 80gsm or lighter.
[Cause]
Being subject to the property of the paper itself, the curl [a] at the corner of the front or rear side of the leading edge of paper may
sporadically become large after passing the fixing assembly depending on the type of paper.
If the corner curls severely, it gets stuck with the guide [b] of the flapper after fixing and the above mentioned symptom occurs.
[Service work]
1) Identify the paper type with which the symptom occurs and change the setting value of the appropriate location from Service
Mode > Mode List > COPIER > "Option" to "-1".
-Thin paper (52 to 63 gsm): IMG-FIX > Change " TMP-TBL5".
-Plain paper 1 (64 to 75 gsm): CUSTOM > Change "TMP-TBL".
-Plain paper 2 (76 to 90 gsm): IMG-FIX > Change "TMP-TBL7".
-Recycled paper 1 (64 to 75 gsm): IMG-FIX > Change "TMP-TB11".
-Recycled paper 2 (76 to 90 gsm): IMG-FIX > Change "TMP-TB13".
The range of setting is from "-2" to "+2" ("0" by default).
Change of the setting value by "1" lowers the fixing control temperature 5 degrees Celsius, so that the curl is reduced.
2) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve sufficiently, then change the setting value in the step 1) to "-2".
[Caution] Change of the setting lowers the fixing control temperature and poor fixing may occur.
3) Output the image having shown the symptom, and check that the symptom does not occur.
