2) controlling a driving unit for moving the position of the toner cartridge in order to move a toner cartridge that needs to be replaced to a specified replacement position preset for toner cartridge replacement, when the necessity of replacing a toner cartridge is detected in step 1), wherein
step 2) includes a step of controlling said driving unit in order to move each toner cartridge to a printable position, and to move the toner cartridge that needs to be replaced back to said replacement position after a specified printing is completed, when a printing instruction is received while the toner cartridge to be replaced has been moved to said replacement position and is ready to be replaced.
10. An image forming method as claimed in claim 9 , wherein
said driving unit has a rotary driving unit for rotating a rotatable cartridge holding unit for holding the toner cartridges.
11. An image forming method as claimed in claim 9 , wherein
said plurality of toner cartridges are toner cartridges of cyan, magenta, yellow, and black colors.
12. An image forming method as claimed in claim 10 , wherein
said plurality of toner cartridges are toner cartridges of cyan, magenta, yellow, and black colors.
13. An image forming method as claimed in claim 9 , wherein
the necessity of replacing a toner cartridge is detected in step 1) based on an amount of toner remaining in the toner cartridge.
14. An image forming method as claimed in claim 10 , wherein
the necessity of replacing a toner cartridge is detected in step 1) based on an amount of toner remaining in the toner cartridge.
15. An image forming method as claimed in claim 11 , wherein
the necessity of replacing a toner cartridge is detected in step 1) based on an amount of toner remaining in the toner cartridge.
16. An image forming method as claimed in claim 12 , wherein
the necessity of replacing a toner cartridge is detected in step 1) based on an amount of toner remaining in the toner cartridge.
17. A program product for controlling an image forming device capable of replacing any of a plurality of cartridges, said program product causing the image forming device to execute a process comprising the steps of:
1) detecting necessity of replacing toner cartridges; and
2) controlling a driving unit for moving the position of the toner cartridge in order to move a toner cartridge that needs to be replaced to a specified replacement position preset for toner cartridge replacement, when the necessity of replacing a toner cartridge is detected in step 1), wherein
step 2) includes a step of controlling said driving unit in order to move each toner cartridge to a printable position, and to move the toner cartridge that needs to be replaced back to said replacement position after a specified printing is completed, when a printing instruction is received while the toner cartridge to be replaced has been moved to said replacement position and is ready to be replaced.
18. A program product as claimed in claim 17 , wherein
said driving unit has a rotary driving unit for rotating a rotatable cartridge holding unit for holding the toner cartridges.
19. A program product as claimed in claim 17 , wherein
said plurality of toner cartridges are toner cartridges of cyan, magenta, yellow, and black colors.
