Table 3-14 Print/Stop settings Duration Description 0 msecs The leading edge of the paper stops approximately 28 mm beyond the "black" paper guide of the registration assembly. 100 msecs The leading edge of the paper stops approximately 63 mm beyond the "black" paper guide of the registration assembly. 500 msecs The leading edge of the paper stops just prior to the paper entering the "nip" of the fuser assembly; the nip is the gap between the pressure roller and the hot fusing roller. 600 msecs The leading edge of the paper stops approximately 5 mm prior to the paper encountering the fuser assembly delivery photo sensor flag. 1,200 msecs (Simplex print operation) The leading edge of the paper stops 35 mm past the face-down delivery stacker rollers. The trailing edge of the paper is approximately 30 mm from the "nip" of the fusing rollers. 2,250 msecs (Duplex print operation) The leading edge of the paper has passed through the fuser assembly and into the output stacker rollers. The paper has now reversed direction and entered the duplex accessory. The leading edge of the paper stops approximately 15 mm before encountering the duplex assembly re-pick photosensor (PS1502). If the timer is set to a value that is greater than the job-print time, you can recover the product in one of two ways. ● After the print job is completed press the Stop button to return to the Diagnostics menu before the timer times out. ● After the timer times out, press the Stop button. Activate the door switch to restart the engine and return it to a normal state. When the timer trips, the control panel display shows the message Printing stopped To continue, touch "OK". Pressing the OK button will print the previously selected job. If you do not want the previous job to print, press the Stop button first, and then press the OK button. Component tests These tests activate the selected component. 1. Press the Home button. 2. Open the following menus: ● Administration ● Troubleshooting ● Diagnostic Tests 3. Scroll to the Print/Stop Test item, and then press the OK button. 4. Use the arrow buttons to select the particular component test that you want to perform, and then press the OK button.

Description
0 msecs
The leading edge of the paper stops approximately 28 mm beyond the “black” paper guide of the
registration assembly.
100 msecs
The leading edge of the paper stops approximately 63 mm beyond the “black” paper guide of the
registration assembly.
500 msecs
The leading edge of the paper stops just prior to the paper entering the “nip” of the fuser assembly;
the nip is the gap between the pressure roller and the hot fusing roller.
600 msecs
The leading edge of the paper stops approximately 5 mm prior to the paper encountering the fuser
assembly delivery photo sensor flag.
1,200 msecs
(Simplex print operation) The leading edge of the paper stops 35 mm past the face-down delivery
stacker rollers. The trailing edge of the paper is approximately 30 mm from the “nip” of the fusing
rollers.
2,250 msecs
(Duplex print operation) The leading edge of the paper has passed through the fuser assembly and
into the output stacker rollers. The paper has now reversed direction and entered the duplex
accessory. The leading edge of the paper stops approximately 15 mm before encountering the
duplex assembly re-pick photosensor (PS1502).
