CHAPTER 4: FIRST PAPER FEED SECTION
[ 4 - 26 ]
5. Paper-Width Potentiometer Adjustment
Checks and adjustment
(1) Access into protected area test mode by activating Test Mode No. 9874.
(2) Set the paper fence to the 105mm line on the paper feed tray, and run Test Mode No.1102.
(3) Set the paper fence to the 297mm line on the paper feed tray, and run Test Mode No.1103.
(4) Set the paper fence to the 105mm line on the paper feed tray, and run Test Mode No.721 to confirm whether
the adjustment ended correctly or not. Confirm that the display shows a value between 1020 and 1080
(1050 plus/minus 30). If not, repeat the adjustment from the beginning.
(5) With Test Mode still in No.721, set the fence position to 297mm, and make sure the indication shows a
value between 2940 and 3000 (2970 plus/minus 30). If not, repeat the adjustment from the beginning.
When setting the fence to the given width for above adjustments, make sure to close the fence inward to
the given width. Do not set to the given width by opening the fence. The fence must be moved inward.
Symptoms
If the adjustment is incorrect, the machine judges the paper on the tray to be in a different size. This would
result in either reduced master-making area, or increased master-making area, and may cause the Pressure
roller to become dirty with ink.
