through the proper decurler, and automatically determines the amount of pressure needed at the
different decurlers to reduce the output curl of the paper.
However, with some print jobs, the output prints can be curled more than you desire even with the
automated control setting of the press. There can be other ways to correct the curl before you use the
Paper Curl Correction option; this depends on your press and any optional devices attached to it,
such as the Interface Decurler Module.
The Interface Decurler Module and Paper Curl
If the press is equipped with the optional Interface Decurler Module, then this is another way to
correct paper curl. The Interface Decurler Module is designed with several automated presettings for
controlling paper curl. The module decurler sets the amount of curl correction automatically.
If the automated curl correction Interface Decurler Module does not fix the paper curl, you can select
the curl correction manually from the Interface Decurler Module control panel.
Tip: Using the buttons on the Interface Decurler Module is a quick and easy way to correct curl
without using the Paper Curl Correction option from the Advanced Stock Setup feature.
Another advantage to using the Interface Decurler Module is that paper curl can be adjusted
while the job is printing by simply pressing one of the buttons on the Interface Decurler Module
control panel.
From the Interface Decurler Module, the amount of curl correction is changed by selecting a related
button on the control panel. The LEDs display the current selected amount of curl correction.
The Interface Decurler Module has the following curl correction options on its control panel:
•
Auto Curl button
: This button selects the Auto Decurl function.
•
Manual Curl Up button
: This button selects the three values of manual up curl.
•
Manual Curl Down button
: This button selects the three values of manual down curl.
•
Curl Up and Down indicators
: These indicate the amount of manual curl (up or down) that is
selected.
•
Auto Curl indicator
: This indicates that the Auto Curl Mode is selected.
Correcting Paper Curl from Advanced Stock Setup
If not the press or the Interface Decurler Module corrects the paper curl, then use the Paper Curl
Correction option to compensate for paper curl. Paper Curl Correction options are based on the job
type and image density ratio.

Tip: Changing the default setting can be considered a temporary solution because
environmental conditions vary from day to day. It is recommended that upon completion of
the print job, you return the option to its default setting.
Important: Always run several test prints, evaluate the output, and if necessary, readjust the
values before running your print job. This ensures that the desired output is achieved.
