12.3.1 Scheduled Servicing Basic Procedure
0009-5839
- As a rule, provide scheduled servicing every 250,000 prints.
- Check with the Service Book before setting out for a scheduled service visit, and take parts for which replacement is expected.
- If the power plug is left connected for a long time in a place subject to dust, humidity, or oil smoke, a fire hazard is a possibility (i.e., the dust collecting
around the plug can absorb moisture, resulting in insulating failure). Be sure to disconnect the power plug on a periodical basis, and wipe off the dust
and dirt collecting around it.
<Work Procedure>
1) Report to the person in charge, and check the general condition.
2) Record the counter reading, and check the faulty prints.
3) Make the following checks, and clean/adjust the items that are indicated:
T-12-3
4) Check the waste toner case.
If half full or more, dispose of the waste toner in a vinyl bag or the like for collection; or, replace the waste toner case.
- If you need to dispose of the waste toner, be sure to do so in strict accordance with the regulations imposed by the local authorities.
- Do not dispose of waste toner in a fire. Doing so may cause an explosion.
5) Clean the copyboard glass and the reading glass.
6) Make test copies.
7) Make sample copies.
8) Check the operation of the leakage breaker.
With the power switch at ON, push the test switch of the leakage breaker to see that it operates normally (i.e., the breaker switch shifts to the OFF side
to cut off the power).
If the leakage beaker fails to operate normally, replace it, and run a check once again.
<Resetting the Breaker>
When you have made the check, turn off the main power switch, and turn on the breaker switch, and then turn the main power switch back on.
9) Put the sample copies in order, and clean up the area around the machine.
10) Record the final counter reading.
11) Fill out the Service Book, and report to the person in change. Be sure to update the history of checks on the leakage breaker in the Service Book.
