- High resolutions of 2,400 x 1,200 dpi maximum, coupled with the exceptionally light-fast, water-proof and ozone-proof five-color pigment inks of Y, M, C, PBK
and MBK, deliver high-quality photographic picture quality.
- Black ink suitable for the selected media type is automatically selected from two types of black ink, "black ink" for vivid and glossy printing and "matte black
ink" for matte and high-quality printing.
- A 160-by-128-dot-large LCD
- One-inch wide printhead having 2,560 nozzles per color, which are as many as the those of the existing models. High-density printhead technology "FINE" that
can satisfy both of beautiful and fast printing requirements of a high order is employed for accurate ejection of ultrasmall 4-pl drops of ink to the target positions.
Prints with 2,400 x 1,200 dpi resolution can be made at a high speed.
- Imaging processor "L-COA" incorporated for high-speed image data processing. High-speed processing of 5-color, 12-bit large-size images and printer control
for high-accuracy operation of high-density head can be performed with a single chip.
- Standard support for 10Base-T/100Base-TX/1000Base-T and USB 2.0 Hi-Speed.
- Borderless printing on and auto cutting of roll media.
- The hard disk is installed for better print job management.
- All operations such as loading the roll media and cassette paper can be carried out at the front (top) of the printer.
- The printer can be installed with its back in touch with the wall, requiring no installation space at the back of the printer.
- A subtank mounted at the ink port allows you to replace the ink tank during printing.
- The pressure of suction from the borderless printing ink catch groove changes automatically with the media size, preventing shift of media edges and staining of
the backside of the media.
- A printhead having nozzles (I-shaped nozzle) with a new shape reduces ink mist, ensuring superfine printing.
- Data scanned using CanoScan can be easily printed on large-size paper just like a dedicated copier. Just pressing the Start button allows you to blow up an original
of up to A3 size in collaboration with Canon Image RUNNER.
- Compatibility with e-maintenance/imageWARE Remote allows centralized management of customers' printer information.
Functional enhancements new to this model include:
- Compatible with a large-capacity 300-ml ink tank in addition to the existing 130-ml ink tank.
