1.11.2  Differences between AcuLaser C900 and AcuLaser 
C1000
AcuLaser C900 is different from AcuLaser C1000 in the following points:
 Usability
 The both-way postcard is added to the paper sizes supported (for domestic 
models).
 The toner cartridge must be replaced while the printer is powered on.
 Specify the toner to replace from the driver, when replacing it before it 
expires.
 The standard paper feed device is just one tray, but you can add one more 
optional cassette.
 Service
 The fuser oil roll is removed, and the service life of Photoconductor Unit and 
Transfer Belt are extended.
 Improving the AIDC control upgrades the picture stabilization.
 Since Waste T Box is not set with Photoconductor Unit, the packing box 
becomes compact.
 The printing density level, second transfer voltage, and fuser temperature can 
be adjusted.
 The ESCPAGES-02 command can be used to print Engine Status Sheet.
 The life of the Fuser Unit is elongated and also there is no worry about 
breakage of belts. Therefore, the “printing impossible” error caused by 
expiration of life does not occur and the “near end” warning is not given.
 The toner supplied with the main unit has a shorter service life than the one 
designated commercially as consumable.
 Since Waste T Box is not set with Photoconductor Unit, the Waste T Box has 
a shorter service life than Photoconductor Unit.
 After Fuser Unit is replaced, the counter must be cleared using the exclusive 
tool.
