The cursor blinks at the top data.
Five counters can be selected with the "#" and " " keys.
In the state , input a desired setting number of 6 digits with the ten-
key.
After input of 6 digits, shift to another counter with the "#" and " "
keys as necessary. When all necessary counters are completely in-
put, press the START key.
"STORED" will be displayed with the set values stored into the memory.
For checking, retry this mode.
Note:
This counter indicates the printer use conditions such as numbers of
printed pages from the beginning of use. In the normal memory clear
condition, the counter will not be reset.
In conditions including damaged memory contents caused by repairing
the panel, this counter should be reset or cleared in addition to the ordi-
nary memory clear.
Rapid key 05: Paper feed aging
The mode is used for aging related to the printing. In this mode, the
following modes are provided.
Blank paper aging mode (ALL WHITE AGING)
Whole black print aging mode (ALL BLACK AGING)
4% printing aging mode (4% AGING)
After selecting the paper-pass aging mode in the print diagnosis mode,
input the number of each mode above with the ten-key, and the mode
will be executed. The detailed specifications of each mode are described
as follows. Here, the operation in each mode is stopped only when the
STOP key is pressed by the operator or a printing-impossible error oc-
curs.
• Blank paper aging mode
In the mode, printing is continued in the whole white (white paper)
printing pattern until the STOP key is pressed by the operator. (In the
printing area)
• Whole black printing aging mode
In the mode, printing is continued in the whole black (whole black)
printing pattern until the STOP key is pressed by the operator. (In the
printing area)
Rapid key 06: Bias adjust mode
The mode is used to adjust the printing density of the printed image. The
image printing density is adjustable in seven steps of 1 to 7.
For details, refer to the following table. (For selection, use the keys 1
thru 7.)
Rapid key 07: Life set mode
The mode is used to set the life counter of the printer and the counter of
the auto feeder at desired values. For setting, proceed with the following
procedure.
When the life counter setting mode is selected, the following will be is
displayed.

Rapid key 08: Life all clear
The mode is used to clear the life counter of the printer of the counter
of the auto feeder.
Note: The counter shows the operational state of the printer (e.g. how
many sheets have been printed since start of use?). The ordi-
nary memory does not reset the counter. Accordingly, it is nec-
essary to reset this counter in addition to the ordinary memory
clear if the content in the memory on the control PWB is broken
because of PWB repair, etc. (In the production stage, it is nec-
essary to execute this in the last process.)
Rapid key 09: Life entry mode
(For Serviceman temporary counter)
The mode is used to set a desired value for the judgment value (alarm
judgment counter value) of the general purpose life counters 1 thru 3 of
the printer. If the life of a consumable part (developer,imprinter, etc) is
set, the model which has the error display and RMS function will inform
RMS when the counter reaches the set value. For setting, proceed with
the following procedure.
When the life counter setting mode is selected, the following will be
displayed.
The cursor blinks at the top data.
Three counters can be selected with the "#" and " " keys.
In the state , input a desired setting number of 6 digits with the ten-
key.
After input of 6 digits, shift to another counter with the "#" and " "
keys as necessary. When all necessary counters are completely in-
put, press the START key.
"STORED" will be displayed with the set values stored into the
memory. For checking, retry this mode.
Note: The counter shows the operational state of the printer (how many
sheets have been printed since start of use? and others). The
ordinary memory does not reset the counter. Accordingly, it is
necessary to reset the counter or do the clear process in addi-
tion to the ordinary memory clear if the content in the memory
on the control PWB is broken because of PWB repair, etc. (In
the production stage, it is necessary to execute this in the last
process.)
Rapid key 10: Top adjust mode
As the method to adjust the top margin for printing, adjust top margin
adjusting VR on the PWB. If this mode is used at this time, adjustment is
possible without the printing test every time when VR is turned.
For the practical use, determine the adjusting value on the basis of the
old data, and adjust to the determined value in this mode. Then, check it
with the printing test.
