47CHAPTER 6MAINTENANCE AND INSPECTION6.1 MAINTENANCETo maintain the equipment always in its best condition, it is important to perform maintenancechecks and record the results. Thus, potential problems can be detected early and trouble can beavoided.6.1.1 Daily checkWithout printer paper, you cannot obtain necessary information. Therefore, check the remainingquantity of printer paper as follows: (1) Open the paper cover on the front panel.(2) Check the quantity of printer paper remaining. If red lines appear at the edges of the paper, replace it with a new roll (the red lines indicate there is one meter or less remaining).(3) If there is a sufficient quantity of paper, or after a new roll of paper has been set, close the paper storage cover.6.1.2 Periodic checkThe self-diagnostic tests check the status of each function of the equipment on a per-block basis.Conduct periodic checks as directed below. (a) Operating procedure See Section 5.5, Self-Diagnostic Tests, for further details.

504) Other checks by the self-diagnostic testsa. Checking the receiving toneDuring tests, if the equipment is normal, a soft tone will be heard. If this tone is notheard, or if the tone is unusually loud, either the CMN-2330 receiver board or theCDJ-2330 is likely to be malfunctioning.b. Checking the alarm buzzer soundDuring message-processing tests, if the equipment is normal, the alarm buzzer willsound. This alarm can be deactivated by pressing the ALARM OFF switch. If thealarm does not sound or if it is unusually loud, either the CMN-2330 receiver boardor the CDJ-2330 main processor board is likely to be malfunctioning.After the alarm has sounded, if it cannot be deactivated using the ALARM OFFswitch, either the H-7SZJD0002A main switch or the CDJ-2330 main processorboard is likely to be malfunctioning.c. Lamp testsThe lamps on the front panel blink for about three seconds prior to the start of themessage-processing tests.During the tests, if the equipment is normal, all LEDs other than POWER will blinkat intervals of about 0.5 seconds. If blinking is abnormal, the H-7SZJD0002A mainswitch or the CDJ-2330 main processor board is likely to be malfunctioning.Also, the alphabetic display unit will display characters A to Z. If the display isabnormal, the CDJ-2330 main processor board is likely to be malfunctioning.
516.1.3 Other general maintenance and check items In addition to periodic checks by the self-diagnostic tests, it is recommended to check thefollowing periodically.CAUTIONWhen loading the printer paper, cut the leading edge straight. Uneven cuttingmay cause the paper to jam.NOTE:If the “out of paper” alarm activates to warn of paper outage, the receiver cannot bereset to stand-by status just by adding paper. The alarm must be cleared bypressing the ALARM OFF switch after adding paper.
