How do i re- set multi-sensor voltage on epson 4000

You should be able to print the settings from the printer. Press the menu button and go to the reports and print the settings. You can also load the drivers and they will search your network for any available epson printers. I have included a link to the downloads page for documentation and drivers.

One of the sensors in the printer probably has a small piece of paper in front of it or a sensor has gone bad.

Yes, the control board may be bad . Ihave attached a procedure for checking the hall effect sensors, some of which you will not have the special tool needed to preform all the tests. However it will allow you to check the control board which may be bad causing your problem.

10 Revision 001 - March, 2002
Appendix 4 - Hall Effect Sensor Checks (Four Part)
1. Isolate the compressor from the main incoming voltage supply. Lock and tag the
isolation switch in the open position.
2. Allow 15 minutes for the VSD to discharge capacitors.
3. Open enclosure doors to expose the VSD.
4. Check with a suitable meter that all voltages have dissipated before beginning work on
the VSD.
5. Remove rear cover of drive motor to permit rotating by hand.
TEST 1
6. Disconnect Hall Effect Cable from P4 on the Control Board, plug type is DB9 Type.
7. Inspect cable pins and matching receptacle connections for damage or bent pins.
Remove cover of plug and inspect solder connection of the wires for damage.
9. Inspect entire length of the cable for damage. If cable and connections are in good condition,
proceed to Test 2.
TEST 2
9. Confirm supply voltage to the Hall Effect Sensor is present using a digital multi-meter.
10. Disconnect terminal strips P1, P2 & P3 from the bottom of Control Board.
11. Trip and switch off MCB2 and MCB5 to prevent the SGN Intellisys from powering up.
12. Re-connect main incoming supply voltage to the unit. Isolation contactor KM1 should remain
de-energized and the VSD should only receive control power. Caution must be taken as the
panel has voltage present.
13. Set digital multi-meter to DC Volts.
14. Connect Black probe of multi-meter to either of the 2 pins of P16.
Note: P16 is located on the Control Board, slightly less than half way down and towards the left side.
P16 is marked and described as 2 small bare pins. P16 is the ground connection for the Control
Board.
15. Locate the small transistor just above Pin 3 on terminal strip P1. The transistor has 3 pins on
the left side. The pins are numbered 1 at the top, 2 in the middle and 3 at the bottom.
16. Connect Red probe of multi-meter to Pin 3. The voltage should be between +11 and +14 Volts
DC.
17. If voltage is not present, replace the Control Board.

11 Revision 001 - March, 2002
TEST 3
17. Connect special adapter XXXXXXXX between P4 on the Control Board and the Hall
Effect Sensor Cable.
19. Set digital multi-meter to DC Volts.
20. Connect Black probe of multi-meter to either of the 2 pins on P16.
21. Connect Red probe of multi-meter to Red wire of the adapter. Rotate motor by hand and
observe measurement. The meter should read between +10 and +12 Volts DC.
22. Repeat the test with the Black wire of the adapter. The meter should read between +10 and +12
Volts DC.
23. Repeat the test with the Yellow wire of the adapter. The meter should read between +10 and +12
Volts DC.
24. If voltage does not rise to between +10 and +12 Volts DC for any of the 3 sensors, replace the
Hall Effect Sensor Assembly.
TEST 4
25. Set digital multi-meter to Ohms.
25. Connect multi-meter between Purple and Green wires of special adapter XXXXXXXX. The meter
should show a resistance value of approximately 150 Ohms ± 20% (New Hall Effect Sensors)* at
70° F (20° C) ambient temperature.
27. If correct value is not confirmed, replace the Hall Effect Sensor Assembly.
Note: Two temperature ranges (130° C and 150° C) of Hall Effect Sensor have been used. Typically,
the 50/60hp (37/45kW) units use a 130° C sensor and the 75/100hp (55/75kW) units use a 150°C
sensor. All sensors have a small band near the sensor end of the cable.
The 130° C sensor has four digits such as 6622 on the band. The 150° C sensor could have either a
four digit number with a star on each side (*6752*) or a four digit number followed by a star and the
letter E (6752*E) or a four digit number followed by an E (7652E).

Very old question but not a hard job. Watch this video. :http://www.inkjetcarts.us/support/article/epson-pro-4000-7600-9600-ink-bay-csic-sensor-replacement-tutorial-video-115.html
Or, in the field repair guide you can find the info to turn off the sensors. Google "disable ink sensor epson 4000", thats how I found it, I run all my off. DO NOT DO THIS unless you use the clear refill ink carts that let you see the ink level. NEVER let your printer head run dry.

You need to select the correct Printer Profile for the type of paper you are using. If you are using non-Epson paper, you need to download the ICC Profile from the paper mfg. website.

You also need to check if the paper is comparable to an Epson paper that the printer supports. If the paper your using is not comparable to any Epson paper the printer supports then you might want to try using another kind of paper. Epson prefers Epson Paper. You can also try any non-Epson paper as long as it is comparable to any Epson paper the printer supports. Try to go to their website and look at the printer's specifications. It lists all type of paper the printer supports.

P0139--O2 Sensor Circuit Slow Response-Bank 1 Sensor 2

P0152--O2 Sensor Circuit High Voltage-Bank 2 Sensor 1

P0300--Random Multiple Cylinder Misfire


I would suspect that the camshaft position sensor is bad. This is a quote from the tech manual:

The Powertrain Control Module (PCM) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The PCM constantly monitors the number of pulses on the signal circuit. The PCM compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the PCM receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the PCM. Some PCM systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the PCM misfire diagnostic will likely be affected.



The part costs $50.....simple to change. It is NOT the O2 sensors so don't go wasting money on those. They are being affected due to related symptoms....they fault because the problem is happening upstream.

E520 is a 2nd BTR sensor error. It is usually caused by waste toner getting on the sensor. Turn off the printer and open the top panel. Lift up the orange handle to unlock the PCU and remove the PCU by lifting it up using the carry handle. Be careful with the PCU drum as it is easily scratched and avoid bright light. Inside the printer on the rear "wall" is a spring loaded cover which can be pushed down to uncover the sensor. It will stick in the down position, do NOT try to force it up again (it will spring back into the right position when the PCU is refitted). Give the sensor a wipe with a soft cloth and refit the PCU. Close the lid and turn back on, with luck all will now be well. If you still have the same error it is time to get proffessional help unless you are experienced at testing voltages and taking printers apart.

Hope this helps, please take a moment to rate this solution.

Error code 00010030 signifies that there is some failure with the Multi Sensor. The Multi Sensor is located on the Printhead Carriage, and consists of a blue light, and the sensor itself. If you look at the Printhead Carriage, you'll notice a graphic of a pair of scissors on the side. Right below that is where the sensor is located. Dust, debris, and excess ink may have accumulated over the sensor, causing it to give a false error code. Clean it, and if that doesn't work, replace the sensor.

the sensors cant see paper on the perforated part/side.
same goes for transparencies, the printer can't see it

Your printer supports the following media types:

Epson Bright White Paper
Epson Iron-on Cool Peel Transfer Paper
Epson Photo Paper Glossy
Epson Photo Quality Self-adhesive Sheets
Epson Premium Photo Paper Glossy
Epson Premium Photo Paper Semi-gloss
Epson Premium Presentation Paper Matte
Epson Premium Presentation Paper Matte Double-sided
Epson Presentation Paper Matte
Epson Ultra Premium Photo Paper Glossy

If you had to push the tray up hard, it could just be that the sensor is now mis-aligned and not detecting the draw is closed. You can check the voltages from the sensor to determine if the sensor is switching. Get yourself a service manual for the printer (aaprox £3.50/ $7.00) to help you get to the sensor and test it's funtion.
