925.xx Service Fuser Error on a Lexmark T64x Series Printer

Explanation of the error message

A 925.xx Fuser Error
message indicates that the printer thinks the wrong fuser lamp or fuser assembly is installed.

Resolution

If this is the first time you have seen the error, turn the printer off.

Leave the printer off for at least 10 seconds before turning it back on. This gives the printer a chance to reset.

If this does not clear the fuser error, check the following:

If the fuser unit
was recently replaced
, confirm that the correct fuser unit was installed.

If possible, put the old fuser unit back into the printer.

If the error message goes away, please check that the new fuser unit is the correct one for this printer model. (If you need the correct part number, contact the Lexmark Technical Support Center.)

If the fuser has not been replaced recently
, you may want to check how the printer is plugged into the wall.

Make sure the printer is plugged straight into the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in the printer which can trigger a false fuser error. Verify also whether the printer works on a

110

or

220

volt source by checking its Power Label on its back and ensure that the power outlet matches its working voltage rating.

If the printer is already on a wall outlet, try plugging the printer into a different outlet, if possible.

If the fuser error continues, the printer will need to be examined by a service technician and repaired as necessary.

Still need help?

Please contact Lexmark Technical Support if you need additional assistance.
NOTE:
when calling for support, you will be asked for your machine/model type
and serial number
(SN). If you need help locating these

Please call from near the printer in case the technician on the phone asks you to perform a task involving the printer.
