Chapter 4 Failure & Repair Analysis
4.4 TROUBLESHOOTING TIPS
4.4.01 Preliminary Checks
1. Is the unit operated under the proper ambient conditions?
2. Is the paper being used made specifically for xerographic printing?
3. Have the toner cartridge and image drum been replaced as recommended?
4. Has the image drum cartridge been installed properly?
5. Is Okidata toner being used?
4.4.02 Tips for Preventing Image Problems
1. Do not let anything touch the surface of the image drum.
2. NEVER expose the image drum to direct sunlight.
3. Do not touch the fusing unit. Oil from your skin can cause fusing temperature variation.
4. Do not expose the image drum to light for more than five minutes.
5. Do not touch the transfer roller. Touching the transfer roller may cause incomplete toner
transfer, resulting in faded output.
4.4.03 Common Problems
1. The display is blank.
Check that the power switch is ON.
Check that the power cord is firmly plugged into the Okifax 1000
and
the wall outlet.
Make sure that power is supplied to the wall outlet.
2. Nothing happens when you press the operator panel keys.
Power OFF the Okifax 1000, wait 10 seconds, then power ON the Okifax 1000.
Check that the power cord is firmly plugged into the Okifax 1000 and
the wall outlet.
Make sure that power is supplied to the wall outlet.
3. The display tells you to replace paper even though there is paper in the cassette.
Remove the paper cassette and make sure that the paper is firmly stacked in the cassette. Push
the paper under the tabs on the sides of the paper cassette.
4. Your original document jams.
Check the document for wrinkles, tears, or other damage.
Make sure there are no staples or paper clips attached and that the paper is clean and dry.
If the problem persists, make a copy of your document on a photocopier and then fax the copy.
Check for contaminants on the contact image sensor.
Make sure the reference roller is clean and free of contaminants.
