5.1 Both Sides Adjustment Reference If skewing or wrinkling occur during printing, adjust the registration loop amount before making the scan measurement adjustment, the gap adjustment, the chart adjustment or the zoom and image shift adjustment. For details, refer to the HTML User's Guide. When the reference position on the print side is adjusted or [Both Sides Adjust] is selected, mark is printed out on the front sides of charts to be printed, and you can identify from which paper tray the charts are printed out depending on the number of marks. For details, refer to the HTML User's Guide. NOTICE NOTICE A high technical skill is required to adjust the reference position on the print side. Before carrying out this adjustment, contact your service representative. You can change the default screen of the [Both Sides Adjust] screen. For more information, contact your service representative. Making the Both Sides Adjustment for each tray Adjust a misalignment between the front and back sides, which is caused during the duplex printing, for each tray. The following methods are available to carry out the Both Sides Adjustment. - Scan Measurement Adjustment - Gap Adjustment - Chart Adjustment - Zoom and Image Shift Adjustment It is convenient to adjust the zoom ratio and printing position of the back side using scan measurement adjustment or gap adjustment after the zoom ratio and printing position of the front side have been adjusted using the chart adjustment or the zoom and image shift adjustment. You do not need to perform both scan measurement adjustment and gap adjustment. Tips You can register Both Sides Adjustment values in a paper profile with paper conditions specified. If paper conditions are registered, you can carry out printing under the previous conditions even when you have changed a tray to load paper into. For information about how to edit or register a paper profile, refer to the HTML User's Guide. )Scan Measurement Adjustment Adjust the magnification ratio and printing position of the back side with reference to the printing position of the front side. The magnification ratio and printing position of the back side are automatically adjusted by using the scanner function of this machine to measure the gap amount in printing position of the back side to the front side. You do not need to measure the gap amount with a scale. The adjustment is available for paper of all sizes which can be used with this machine. Print out 1 to 20 sheets of the adjustment chart having both front and back sides printed, and scan them 4 times per sheet. The average value of gap amounts in printing position of the back side to the front side, which can be obtained by scanning up to 20 sheets of the adjustment chart, will be calculated in order to adjust the magnification ratio and printing position of the back side. NOTICE NOTICE The [Scan Meas.] adjustment provides the coordination based on the average value of gap amounts, taking into account the gap in printing position between the first and last sheets which can be produced when multiple sheets are output. Performing the [Scan Meas.] adjustment may require readjustment of the "Zoom and Image Shift Adjustment" registered in a paper profile. The [Scan Meas.] adjustment is a simple method to adjust only the magnification ratio and image position of the back side. To adjust both front and back sides, perform the "Chart Adjustment" (page 5-16) or "Zoom and Image Shift Adjustment" (page 5-23). 5-2
