1.12.1 Maintenance Call
Some of the mechanical units used in this printer have counters which count down the
remaining service life based on the proper service life for each unit, and when the
predetermined value is reached, a “Maintenance Call nnnn” message is displayed. If this
message is displayed, it indicates that the end of the service life of the affected unit is
nearing, so it is necessary to replace the affected unit as soon as possible.
If this message is displayed, the “Print?” or “Printing” display message is replaced with the
“Maintenance Call nnnn” message, and after replacing the affected part, it is not cleared
but continues to be displayed until the counter is cleared.
