Chapter 22-3F-2-7If this is the case,1) Turn over the stack of paper in the source (i.e.,cassette). If doing so has caused the paper to curl morethan before, turn back over the stack. If the curling isstill appreciable and the machine fails to stack thepaper properly, try enabling heavy paper upward curlmode.b. Enabling Heavy Paper Upward Curl1) Turn off the host machine.2) Set the bits of SW104 on the finisher controllerPCB as follows:F-2-83) Turn on the host machine.- When this mode item is enabled, the machinechanges its operation it executes after the start of stackedging, thus ensuring that the paper will be stackedproperly.- When this mode item has been enabled, changes inconditions (e.g., the use of paper with little curl ordelivery of paper with downward curl) can prevent themachine from stacking the paper properly. It isimportant, therefore, to be sure of the type of paperused by the user before enabling this mode item.2.1.5 Stack Delivery Mode 0009-2567a. OutlineDepending on the selected paper handling mode*,condition of paper, and environment, the trailing edgeof paper can rain against the stacking wall and preventthe machine from stacking it correctly (also causing itto prematurely detect an over-stack condition; see thefollowing figure).*For instance, in stack delivery mode other than whenthe stack consists of 6 or fewer sheets of small-sizepaper.F-2-9If this is the case,1) Turn over the stack of paper inside the source (e.g.,cassette). If doing so has made upward curling worsethan before, turn back over the stack. If the upwardcurling still causes the machine to fail to stack thepaper correctly, try enabling stack delivery mode:b. Enabling Stack Delivery Mode1) Turn off the host machine.2) Set the bits of SW104 on the finisher controllerPCB as follows:F-2-103) Turn on the host machine.- When this mode item is enabled, the machinechanges its operation it executes after stack edging toON1 2 3 4 5 6 7 8ON1 2 3 4 5 6 7 8
