Reducing Paper Curling When Outputting To The 5,000-Sheet Stacker Or Finisher - Kyocera Taskalfa Pro 15000c Operation Manual

Using Custom Paper > Setting from the Operation Panel
Reducing Paper Curling When Outputting to the
5,000-sheet Stacker or Finisher
Adjust this setting if curling occurs when outputting to the optional 5,000-sheet Stacker or the Finisher. There are four
types of curling: strong upward curling, strong downward curling, minor upward curling, and minor downward curling.
Strong upward curling
Paper movement
direction
The direction of curl (warpage) after printing changes depending on the difference in the moisture content (ink volume)
on the front and back sides of the paper.
For example, if the moisture content on the front surface of the paper is higher than the back surface, or if printing on
single side of the front surface, the printout tends to curl downward.
On the other hand, when printing on double-sided, if the moisture content on the back surface of the paper is higher than
the front surface, the printout tends to curl upward. For example, the image is printed on the entire of back side of the
paper, and a small amount of text is printed on the front side.
In addition, the direction of curl may increase if the decal adjustment value is configured large in the plus or minus
direction
NOTE
• If the moisture content (ink volume) on the front and back surfaces is similar even in double-sided printing, the
direction of the curl will be canceled and it will be wave edge.
• When the Inverter and Decurler Unit is installed, the curl is corrected and the Printouts are discharged with the front
side facing down when printing on both single-sided and double-sided, except for the 5,000-sheet Stacker and
Finisher tray B. However, the condition of the wave edge may become the downward curling.
• If you want to print in large quantities, check the image quality and print format (single side or double side) of the
original to be printed, make trial prints and check the condition of curl while correcting it.
