3.1 Outline
This section explains procedures for rapid and efficient troubleshooting if trouble
occurs in the printer.
3.1.1 Introduction
First of all, when performing troubleshooting, the following basic parts should be
checked.
1. Look in the printer for any foreign matter and make sure there is nothing there
to hinder normal operation.
2. Carry out printing by setting the printer in the “Pause” state, then press the
[SelecType] button 2 times. Next using the [Paper Feed] switch in the “TEST
PRINT MENU,” select “STATUS CHECK”, then press the [Enter] switch
and print.
From the status sheet, you can Check to see if the cause of the trouble is that
the printer (either the printer unit itself or some major unit) is at the end of its
service life, and check the user inherent panel settings, etc.
3. There should be no market soiling of the outside or the inside of the printer. If
it is extremely soiled, carry out cleaning.
4. Each of the units and parts in the printer should not be missing or damaged,
and should have the normal shape and configuration.
5. Each of the harnesses should be undamaged, and should be correctly
connected to the relevant connector (perpendicularly and in the correct
direction).
6. Each cam and gear in the printer mechanism should have no uneven wear or
be overly worn, and the combinations should be correct.
7. Each type of rubber roller in the printer mechanism should be cleaned and it
should be ascertained whether the cause of the trouble is because of dirt or due
to some other cause.
8. Each type of rubber roller in the printer mechanism should not be unevenly
worn or excessively worn, and their combinations should be correct.
9. As necessary, initialize the NVRAM on the C472MAIN Board (return the
individual customer settings and panel settings to the factory settings).
Carry out initialization by executing “INIT. NVRAM” from the “CLEAR
COUNTERS MENU” in “Maintenance Mode 2."
