Xerox S2011 Fuser Error 010-311: Check the Fuser Version First
By APACE technical team · Published October 31, 2026
A practical checklist for error 010-311 after fitting a fuser in a Xerox DocuCentre S2011 — why the wrong fuser version is the first thing to rule out.
When a Xerox DocuCentre S2011 shows error 010-311 right after a new fuser is installed, the first thing to check is whether the fuser is the right version for the machine. In APACE's support records, a fuser ordered or delivered for the wrong model is the most common cause. Fusers that look identical can use different thermistor connectors, heater power and plugs.
What 010-311 points to
On several Fuji Xerox machine families, the service manuals describe 010-311 as a heat roll thermistor disconnection. For example, the DocuCentre D125/D110/D95 manual lists it as "Heat Roll Thermistor 1 Disconnection Fail". The thermistor reports the fuser temperature to the machine; if the machine cannot read it, it stops with this code.
The exact wording differs between machine families, so always check the service manual for your model. The practical point is the same: the machine is not getting a valid signal from the fuser's temperature sensor.
Why the fuser version matters on the S2011
The S2011 and S1810 fusers are a typical example of parts that look alike but do not interchange:
| Fuser | Thermistor connector | Interchangeable? |
|---|---|---|
| Xerox S1810 | 4-pin | No |
| Xerox S2011 | 5-pin | No |
A 4-pin fuser cannot connect correctly in a machine that expects a 5-pin thermistor connector. Fitting the wrong one leads to errors, poor fusing or paper jams.
The S2011 fuser is shared by several related machines. APACE's S2011 fuser is listed as compatible with the DocuCentre S2011, S2110, S2320 and S2520 and the Fujifilm Apeos 2150 and 2350. The S1810 drum unit, by contrast, also fits the S2011, which is one reason the two fusers get mixed up.
Step-by-step checklist
- Read the label on the fuser you installed and compare it with the machine model. Confirm it is an S2011-type fuser, not S1810.
- Check the thermistor connector. Count the pins and make sure the plug seats fully in the machine socket.
- Check the voltage. APACE's S2011 fuser is listed at 220 V. Make sure the fuser voltage matches the local power supply and machine version.
- Check the regional version for export machines. Overseas machine variants can use different plugs; tell your supplier the machine's country version before ordering.
- Reseat the fuser with the machine switched off and unplugged, then restart.
- If the error remains with the correct fuser, contact technical support with the machine model, a photo of the fuser label and the error code.
How to order the right fuser next time
- State the full machine model and the regional version.
- Give the voltage (110 V or 220 V).
- If possible, send a photo of the existing fuser label and its connector.
- Do not choose a fuser by appearance alone.
FAQ
Can I use an S1810 fuser in a Xerox S2011?
No. The S1810 fuser uses a 4-pin thermistor connector and the S2011 fuser a 5-pin connector, so they do not interchange.
Which machines share the S2011 fuser?
APACE's S2011 fuser is listed as compatible with the Xerox DocuCentre S2011, S2110, S2320 and S2520 and the Fujifilm Apeos 2150 and 2350.
What information does technical support need for error 010-311?
The machine model, a photo of the fuser label and the error code. With these, the team can check whether the fuser version matches the machine.
