USEFUL TECHNICAL INFORMATION: ? Entering Diagnostic Mode… Hold ‘0’ while turning on the power. ? U4-1 codes… A U4-1 code indicates that the fuser took too long to warm up. Usually this means a bad heat lamp or blown thermal fuse. NOTE: After you clear the code, you’ll want to watch the heat lamp to make sure it comes on & cycles out ok. If it doesn’t shut off once the machine comes to ready, turn off the power before you get a melt down (a shorted Triac would be the first suspect if the lamp stays on continuously). To reset the code: (procedure varies slightly from model to model) Once the code is cleared, the display will show ‘dn’ for “done”. For 5016/5018/5021/5028/5126/5321/5328/5818/5820/XC1875/2675 , Enter diagnostics, then enter ‘20’, ‘Print’, ‘3’, ‘Print’, then ‘0’, and ‘Print’ again. The display will show ‘dn’ for “Done”. (Machines with newer software (Tag 6 or 14) do not require pressing the ‘0’… on those, enter ‘20’, ‘Print’, ‘3’, ‘Print’, and then ‘Print again. For 5034: Enter diagnostics, then enter 20’, ‘Print’, ‘3’, ‘Print’, ‘0’, ‘Print’. For 5624/5626/5824/5826/5828:enter diagnostics, then use the ‘P’ button to scroll to “Routines”, then press ‘4’ to choose ‘Routines Mode’. Enter ‘20’, ‘Print’, ‘3’, ‘Print’, then ‘0’, ‘Print’. The display will show ‘dn’ for “Done”. For 5334/5830: Enter diagnostics, then press the ‘Routines’ tab on the Touchscreen. Enter ‘20’, ‘Print’, ‘3’, ‘Print’, ‘0’, ‘Print’. The display will show ‘dn’ for “Done”. ? U4-6 (or L-4) Status Codes “Web End of Life”... After replacing the web you must reset the web counter: The code to reset the web count for all of the models in this style is “10-63”although the procedure for entering the code varies from model to model. Our webs come with a write up which includes how to reset the codes on each & also what to watch out for to help avoid common problems. 5018 style TECH INFO. 5016/18/21/28,5034,5126,5321,5328,5334,5624/26,5818/20/24/26/28/30,XC-1875/2675 ? E-2 Status Code... We get lots of calls about E-2 fake paper jams. The fact of the matter is that E-2 means the main board detected a fault during self initialization. At the point of E-2 being displayed, open and close the clamshell. The original status code that caused the E-2 will be displayed. Then press the “0” key to observe the subcode. This will surely help you to further diagnose the situation. ? U7-1 Status Code “Copy Cartridge Drive Problem / Belt Hole Sensor Fault”... Can be caused by many ailments: 1. Check that the Xerographic drive motor is turning and that the cartridge drive belt is intact. You can watch it turn if you open the toner door, disconnect the rear pivot arm, bias it up and inward to tension the belt (If the belt is not tensioned, you will do damage to the drive), cheat the interlock switch and turn on the machine. 2. Clean the Belt Hole Sensor inside on the front frame. It looks like an LED (can be clear or black). Read the sensor with a meter in ‘Diode Check Mode’, shine a flashlight on the sensor (it should conduct). 3. Check the Blanking Lamp for continuity (the beaded lamp directly above the copy cartridge). Make sure that the lamp is clean. 4. Sometimes the black mylar strip next to the Blanking Lamp comes loose & hangs down or around the lamp, blocking the light, if this is true, trim it back away from the lamp. 5. Check that the Photoreceptor Belt is not slipping on its drive rollers, and that when the cartridge is installed , the belt hole in the PR Belt is on the front side of the machine (It is possible to install the PR Belt backwards). Make sure the clear plastic piece on the side of the cartridge which the sensor looks through is clean. You may also want to try another cartridge. 6. If none of that pans out, the AC Driver Board can be responsible. ? U9-3 “Exposure Lamp Dim, or not lighting”...Either the Exposure Lamp circuit is failing, or the Exposure Sensor isn’t seeing enough light. The Exposure Lamp or Exposure Thermal Fuse could be at fault (diagnostic code” 6-9“ lights the lamp). Sometimes the lamp checks ‘ok’ but is on its way out. Dark rings in the lamp are a tell-tale sign. If it doesn’t light, check the Exposure Lamp, Exposure Thermal Fuse, & Exposure Wiring Harness. The lamp circuit should measure 2.5 ohms or less. If those check ok but the lamp never lights, the AC Driver Board is suspect. If the lamp comes on momentarily and then the machine calls the U9-3, the Auto Exposure Sensor (Located under the Lens Cover standing next to the lens) isn’t seeing the light clearly. The Sensor looks through the mirrors at a white mylar strip. This Reference Strip is located on the underside of the Lead Edge Guide (if the strip is missing, dirty, or damaged, a U9-3 will appear). The Optics, Exposure Sensor, & Reference Strip must be clean. 5018 style TECH INFO. 5016/18/21/28,5034,5126,5321,5328,5334,5624/26,5818/20/24/26/28/30,XC-1875,XC-2675 ? Very Dimly Lit (or Blank) Console... One or more of the 10 console indicator lamps is probably blown. They are soldered onto the console board. We usually replace all 10 (12 for 5034) (if one blows, more are likely to follow). ? Mysterious Thumping Noise (in fuser section)... Can be the Copy Drive Belt slipping on its sprocket. Check for wear on the Fuser Drive Pulley Gear and belt, and for caked up toner residue between the teeth on the Pulley. Check also for lack of tension on belt tensioner (located behind the transfer corotron). ? LIGHT COPIES … So many possibilities… - Clean the optics, the Exposure Sensor (under the lens cover next to the lens), and the white mylar Reference Strip located on the flip side of the Document Lead Edge Guide (to the left of the platen glass). - Toner Ctg… Take out the toner cartridge and see if the well under the ctg (in the DV Unit) has toner in it. Turn the large gear clockwise. It should turn with little resistance and you should hear the auger stirring the toner inside. If not, the auger broke trying to stir the toner. Replace the toner ctg. (shake good). - Transfer Corona…If the problem came on suddenly & is severe, bring a replacement Transfer Wire with you. If the problem is intermittent & severe, the most likely cause is an arcing Transfer Corotron Assembly. - DV Unit… If the DV Latch Handle is broken, copies will be faded, often on one side of the copy. Developer on the Toner Sensor (on the rear of the unit) can also cause light copies. Check the mag roll for even coverage. Pop off the large round plug near the front of the unit (on top of the mag roll portion). Turn the DV Roller Gear clockwise… make sure the auger under the plug is mixing the Developer. Add developer if needed. Sometimes the Large Blue Connector is not making good contact…Best way to check is to remove the small cover on the DV Unit in front of the Blue Connector so that when you install the DV Unit, you can watch all the pins from the machine’s connector seating. Usually, what happens is that the Connector inside the machine gets knocked out of position. - Copy Cartridge…If multi copy runs start good & then get lighter & lighter or if every 2nd or 3rd copy is light, try a different Copy Cartridge. - Diagnostic Adjustments… The Exposure Adjustment gives you very little to work with. Enter diagnostics, then enter code “9-62” (‘9’, ‘Print’, ‘62’, ‘Print’) then select a new number (the range is from 0 to 7 with 7 being lightest). If you want to try changing the Toner Dispense Rate, the code for that is “9-63” (‘9’, ‘Print’, ‘63’, ‘Print’). The range is from 0 to 15. - Last Ditch Efforts… We have found that when all else fails, a piece of black optics tape on the very bottom of the lens (the outer side) will darken the copy up considerably without disturbing the image.

Very Dimly Lit Console... One or more of the 10 console indicator lamps is probably blown. They are soldered onto the console board. We usually replace all 10 at once (if one blows, more are likely to follow).
L-4 or U4-6 Status Codes "Web End of Life"... After replacing the web you must reset the web counter: Hold the "0" while turning the main power on. Then enter "10" & press "Start Print". Enter "63" & "Start Print". Enter "0", display will show CC. Press "Start Print" dn should show. Turn power off & after 10 seconds on again.
E-2 Status Code... We get lots of calls about E-2 fake paper jams. The fact of the matter is that E-2 means the main board detected a fault during self initialization (start-up when power comes up). At the point of E-2 being displayed, open and close the clamshell. The original status code that caused the E-2 will be displayed. Then press the "0" key to observe the subcode. This will surely help you to further diagnose the situation.
U7-1 Status Code "Copy Cartridge Drive Problem / Belt Hole Sensor Fault"... Can be caused by many ailments:
Check that the Xerographic drive motor is turning and that the cartridge drive belt is intact. You can watch it turn if you open the toner door, disconnect the rear pivot arm, bias it up and inward to tension the belt (If the belt is not tensioned, you will do damage to the drive), cheat the interlock switch and turn on the machine.
Clean the Belt Hole Sensor inside the front frame. It looks like an LED (note: some are normally black). Read the sensor with a meter in ‘Diode Check Mode’, shine a flashlight on the sensor and it should conduct.
Check the Blanking Lamp for continuity (the beaded lamp directly above the copy cartridge). Make sure that the lamp is clean.
Check that the Photoreceptor Belt is not slipping on its drive rollers, and that when the cartridge is installed , the belt hole in the PR Belt is on the front side of the machine (It is possible to install the PR Belt backwards). Also make sure that the window in the cartridge which the belt hole sensor looks through is clean. You may want to try switching cartridges as a test.
If none of that pans out, the AC Driver Board may be responsible for the problem.
Mysterious Thumping Noise (in fuser section)... Can be the Copy Drive Belt slipping on its sprocket. Check for wear on the sprocket and belt, and for caked up toner residue between the teeth on the sprocket. Check also for lack of tension on belt tensioner (located behind the transfer corotron).
Fuser Temperature Problems...These babies tend to run HOT! So it is a good idea to set them at the lowest acceptable temperature. This way he fuser roller life is enhanced, the webs won't dry out and the likelihood of the web tearing or wrapping is virtually eliminated.
For 5018/28 hold 0 while turning ON, enter 10, START, 61, START. The current setting (default is 50) will show in the copy count window.
Set it to 0, and check fusing. If need be, increase this in increments of 3.
For 5034, the procedure is a little different: hold 0 while turning machine on, enter 20, START, 0, START and then use the P key to scroll to 10-61, START.
The rest is the same.
