• The atmospheric conditions of the room where the paper is stored, especially those related to
humidity and temperature
• The heat generated during the fusing processes
Tip:
Successful paper curl correction varies from day to day. A successful setting used on one
day cannot be successful on another day. This is especially relevant if the room in which press
is located experiences changes in temperature and humidity.
Automatic Paper Curl Correction
The press is designed with an automated setting to control the curl. This automated setting does not
require the user to make any
Paper Curl Correction
selections. The press automatically sends paper
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.
