Remove and reseat the fuser. Power On Reset the printer.

Check the camshaft follower on the left side. If the
error message persists:
Check the input voltage switch on the back of
the low voltage power supply (LVPS).
Is the voltage level (115/230) properly set?
Go to step 2. Set the switch for the proper
country voltage.
2 Turn the printer off, and remove the rear cover.
Check the connector JFUSER1 for proper
connection to the system card, the cable for
pinch points, and the cable or connector for
any other damage.
Is the cable damaged?
Replace the fuser cable.

3 Remove the fuser. Check the AC and DC
autoconnects on both the fuser and the printer
for damage.
Are the connectors damaged?

Replaced the cable.

SOURCE: I am getting a 122-10

I presume you have not replaced the fuser due to a fault but merely removed it to make the machine lighter when moving it. Did you turn the machine off when you removed the fuser or was it still on. If it was on then not surprised you have the error. I would remove the fuser again and carefully refit it.Make sure it clicks back into place with no real effort. Turn it on again and see if it clears. You can reset the counter manually although this would not clear an error like this. If still no good then must presume you have damaged the fuser and will have to replace it with a new one.

srri but thats the best i can do for you.

I have just bought a new Lexmark C543dn laser printer. When I powered it up it has 122.03 error code showing. I have switched it off and on again but still the same. It is plugged into a proper socket and...

Problem 122.03 error; 122 error; Fuser error Solution What the error means
The 122.03 Error indicates that the printer's fuser unit is heating up either too quickly or too slowly.
What to do
This error normally requires a service call. However, certain rare occurrences, such as a a power fluctuation or a stray static discharge in the vicinity of the printer, can cause a false 122.03 error message to appear. In these cases, the error is only temporary and can be easily resolved without service. Follow the steps in the table to test this.

If possible, connect the printer's power cord directly into a grounded wall outlet. In rare instances, a surge protector or uninterruptible power supply (UPS) can generate false error messages.
Did the error message return?

Yes: Continue to Contacting Lexmark below.
No: Print a test page. If the page prints, the printer is functioning correctly.

Error 120.10 service fuser error

Service Fuser Error appears on your Lexmark printer when the fuser does not warm to the required temperature. For this error on this Lexmark model, the manual states you should power off the printer and power it back on, and if it is not plugged into a wall power point, change it to a power point mounted directly on the wall. Personally, I never got a Lexmark printer to work doing this, but this is in the manual. If this won't help, and the printer is under warranty, you should log it in with the servicing company.

If the printer is out of warranty, your next option is to change the fuser which costs around $350, so I think you would be better off getting a new printer unless you find a second hand one on Ebay.

Says 122.05 Service fuser error on screen

A 122.05 or 122.06 Fuser error indicates that the printer/MFP has detected a problem with the fuser unit. A service call will probably be required to solve this issue. However, certain rare occurrences, such as a power fluctuation or a static discharge in the vicinity of the printer/MFP, can cause a false 122.05 or 122.06 error message to appear. In such cases, the error is only temporary and can be easily resolved without service.

Lets assume this is a power problem, do you have a digital or remote phone unit close to the printer or your computer,a) try moving it for a day or so to test to see if that is the problem b) is it connected to a power surge unit (if so take it out and plug directly into the outlet) power surge strips or units have fuses in them it may be going also.always remember shut down units properly for these test
shut down machine, then power up so the computer and the printer are reading eachother properly. if not go to
