Chapter 22-12.1 Basic Adjustment2.1.1 Upward Curl Mode 0009-2563a. OutlinePaper tends to curl upward in certain conditions,preventing normal delivery/stacking. (See thefollowing figure.)F-2-1If such is the case,1) Turn over the stack of paper inside the paper source(e.g., cassette). If doing so makes the upward curlingworse than before, turn back over the stack. If thepaper still develops upward curl and, thus, fails todeposit itself normally, try enabling the upward curlmode item.b. Enabling the Upward Curl Mode1) Turn off the host machine.2) Set the bits of SW104 on the finisher controllerPCB as follows:F-2-23) 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 downward curl) can cause improperstacking. In this regard, it is very important to studythe type of paper that is most often used by the userbefore enabling this mode item.2.1.2 Special Curl Mode 0009-2564a. OutlineIf paper with irregular curl is deposited*, its edges canblock the delivery slot of the finisher, pushing forwardthe exiting stack when the next sheet arrives. (See thefollowing figure.)*LDR size only (mainly, Boise Cascade; 75 g/m2 inweight).F-2-3If this is the case,1) Turn over the stack of paper inside the source (i.e.,cassette). If paper starts to curl more than before, turnback over the stack. If the curling is not corrected as aresult, try enabling the special curl mode item.b. Enabling Special Curl Mode1) Turn off the host machine.2) Set the bits of SW104 on the finisher controllerPCB as follow:ON1 2 3 4 5 6 7 8Paper withappreciable body.
