Chapter 44-5F-4-43) Turn on the host machine.- When this mode item is enabled, the paper surfacedetection mechanism is executed for every sheet ofpaper (instead of every 5 sheets) and the timing atwhich the delivery tray is moved down is advanced sothat the paper will be stacked properly.- When this mode item has been enabled, changes inconditions (e.g., the use of paper with little curl) canprevent proper stacking. In the light of this, be sure tocheck the type of paper most frequently used by theuser before enabling this mode item.4.3.1.3 Downward Curl Mode 0009-2565a. OutlinePaper tends to curl downward in certain conditions,preventing normal delivery/stacking. (See thefollowing figure.)F-4-5If such is the case,1) Turn over the stack of paper inside the paper source(e.g., cassette). If doing so makes the downwardcurling worse than before, turn back over the stack. Ifthe paper still develops downward curl and, thus, failsto deposit itself normally, try enabling the downwardcurl mode item.b. Enabling the Downward Curl Mode1) Turn off the host machine.2) Set the bits of SW104 on the finisher controllerPCB as follows:F-4-63) Turn on the host machine.- When this mode item is enabled, the machinechanges the speed of its stack delivery roller to ensureproper stacking.- When this mode item has been enabled, changes inconditions (e.g., the use of paper with little curl orpaper with upward curl) can cause improper stacking.In this regard, it is very important to study the type ofpaper that is most often used by the user beforeenabling this mode item.4.3.1.4 Heavy Paper UpwardCurl Mode 0009-2566a. OutlineDepending on the selected paper handling mode andthe condition of paper*, upward curl can develop andprevent the machine from stacking the paper properly.(See the following figure.)*For instance, heavy paper cover mode and single-side binding are selected, and the front/back cover isLDR and 157 g/m2 or more.F-4-7ON1 2 3 4 5 6 7 8ON1 2 3 4 5 6 7 8
