Fatal errors (HP LJ 1010 series printers)
If all of the printer lights are on (solid) and you cannot resolve the error by turning the printer off and on,
then a fatal error has occurred. Two errors scan be identified: failed communication between the
formatter and the engine, and a failed fuser. If neither of these is identified by using the following
procedure, replace the printer.
1 Press and hold the G
O
button. The printer shows a secondary error pattern.
2 If the A
TTENTION
light illuminates as the secondary error pattern, the formatter and engine are not
communicating.
Ɣ Check the ribbon cable between the formatter and ECU, and check all other connections.
Ɣ If the error persists, replace the ECU.
Ɣ If the error persists, replace the printer.
3 If the G
O
and R
EADY
lights illuminate as the secondary error pattern, the fuser (fixing assembly) has
failed and must be replaced.
