Canon Perfect Binder A1 Troubleshooting Manual page 30

If the paper is not curled, go to the step 2). If the paper is curled, perform curl correction following the procedure below:
[Reference]
The tolerance of curl on the paper [1] that is delivered from copier host machine should be 10mm or less in regard to the height
[a] of the curl, and the length of curl [b] should be 50mm or more.
Even if the curl amount is within the aforementioned specification, the condition of spread glue may be affected by a small amount
of curl due to the variation of elasticity of paper depending on paper type. If 1FA7 or 1FA9 jam occurs, it indicates the possibility
of paper curl. Check if the paper is curled.
1-1) Select Additional Functions> System Settings> Paper Type Management Settings.
1-2) Select the paper type to edit from the list and [Details/Edit].
1-3) Press [Change] in [Curl Correction Level].
1-4) Press [-] and [+] to adjust the correction level for printing in face-up/down modes respectively.

the corrected amount.
