4.2 Maintenance and inspections

Regular replacement parts

There are no parts that require regular replacement on the main unit.

TROUBLESHOOTING

Note

Regular replacement parts are the parts that must be replaced regularly without fail to ensure a constant standard of functionality with the product (parts which have a great effect during malfunctions despite there being no visible changes or damage to the outsi de of t he devic e.) It is recommended that the stipulated parts are replaced during the earliest regular service.

Life-expectancy chart for co ns umable parts

There are certain parts that may require replacement owing to deterioration or damage at least once during the period of product warranty. The expected average life span for parts that may require replacement owing to defects is shown below.

4.4 Ratings and adjustments

Mechanical adjustments

There are no mechanical adjustment required for the finisher.

Electrical adjustments

Distance sensor adjustment

The distance sensor must be adjusted when the finisher driver’s circuit board or the distance sensor is replaced, and when an error occurs in the back-up RAM.

The distance sensor is adjusted prior to leaving the factory. It is therefore not necessary to make these adjustments at the time of installation, but they must be corrected if the finisher driver circuit or distance sensor is replaced after this. Initial corrections must also be made when an error occurs in the back-up RAM. The procedure for this is as follows:

Confirm that the voltage of the lithium battery in the finisher driver circuit board is 2.7V

or more. Set the finisher driver circuit board’s dip switch (SW1) #1 to OFF, #2 to OF F, #3 to OFF

and #4 to ON. Insert one sheet of white paper in each of the trays.

Press the push switch (SW2). (To start adjustment)

Move the trays to each distance adjustment position and load the distance data.

LED2 will blink during the adjustment process, and will be illuminated when adjustment

is complete. If correct adjustment cannot be performed, LED2 will be extinguished and the system will shut down in that position.

4.5 Initial inspections

Confirming the installation environment

Confirm that the environment in which the device is to be used conforms to the following standards:

a b c

Confirm the paper to be used

a b

Confirm that the power supply is within +/-10% of the rated voltage. Ensure that the device is install on a flat surface. Ensure that the surrounding temperature is between 10 and 32.5 degrees Cel-

sius, and the surrounding humidity is between 20 and 80% RH. Avoid areas when the device may be exposed to ammonia gas, high tempera-

tures and humidity (nearby water supply faucets, water boilers and humidifiers,) excessive coldness, naked flames or excessive dust.

Avoid areas where the device will be exposed to direct sunlight. If this is unavoidable, ensure that the device is protected by a curtain or some other form of screen.

Ensure the area is well ventilated.

Is the paper recommended for use with the finisher being used? Is the paper damp?

Check the above points by inserted a new pack of paper and performing a test run.

Others

If the finisher is stored in a cold area, such as a warehouse during the w inter months, and then brought into a warm room, condensation may build up on the various parts and lead to a wide range of trouble. Either dry off all parts of the device or leave it to stand with the electricity on for between 10 to 20 minutes when condensation has built up.
