3.5 Belt CRUM

3.5.1 General Description

The Belt CRUM, used in the transmission belt of the photoelectric Dry Color Laser Printer, is mounted on the belt. It
exchanges information of the belt with the body, identifies qualification status of the belt and measures its usage.

3.5.2 Description of Operation

3.5.2.1 Recognition of the qualified belt

- It judges whether the belt is qualified or not, by reading the data of EEPROM.
- When the data of the EEPROM is normal, the machine will operate normally, and when the data is abnormal

or unrecognizable, it will output alarm message and stops printing

3.5.2.2 Measurement of belt usage

- By recording the rotation number of the belt into EEPROM, the belt CRUM lets you know the number used

and the number that may be used.
