3.1 Outline
This section explains procedures for rapid and efficient troubleshooting if
trouble occurs in the printer.
3.1.1 Check Before Troubleshooting
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.
With the printer in "READY" condition, press the [Menu] key one time, and
then press the [Paper Feed (
∧
/
∨
)] keys to select "TEST PRINT". Press the
[Menu] key again one time, press the [Paper Feed (
∧
/
∨
)] keys to select
"STATUS CHECK". After these have been selected, press the [Menu] key
two times to 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.
(Refer to "Step 9" when in properties panel settings.)
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 BOARD ASSY., MAIN (return
the individual settings and panel settings to the factory settings).
Carry out initialization by executing "Panel Initialization" in "Maintenance
Mode 1".
