Abstract
A color laser printer includes a transfer belt unit including a transfer belt with reference marks, and a drive mechanism for the transfer belt, wherein the transfer belt unit includes a data storage unit (EEPROM) that stores color correction data and position correction data. When the transfer belt unit is new or replaced, corrections for color difference and position difference are performed based on the color correction data and the position correction data.
Claims15
A color laser printer comprising:
- a detachable transfer belt unit having a data storage unit that stores color correction data and position correction data;
- a detecting unit that detects whether the transfer belt unit is detached and reattached or replaced with another transfer belt unit with the same configuration;
- and
- a correcting unit that performs corrections for color difference and position difference based on the color correction data and the position correction data stored in the data storage unit when the detecting unit detects that the transfer belt unit is detached and reattached or replaced with another transfer belt unit with the same configuration.
A color laser printer comprising:
- a detachable transferring means having a storage means that stores color correction data and position correction data;
- a detecting means that detects whether the transferring means is detached and reattached or replaced with another transferring means with the same configuration;
- and
- a correcting means that performs corrections for color difference and position difference based on the color correction data and the position correction data stored in the storage means when the detecting means detects that the transferring means is detached and reattached or replaced with another transferring means with the same configuration.
A method of correcting color and position difference for a color laser printer, the color laser printer having a detachable transfer belt unit with a data storage unit that stores color correction data and position correction data, wherein when the transfer belt unit is detached and reattached or replaced with another transfer belt unit with the same configuration, the method comprising correcting color difference and position difference based on the color correction data and the position correction data.
