The printer has both mono-directional and a bidirectional printing mode, for faster printing. The one inch wide print head has a resolution of 2880 x 1440 dpi. There are four different ways to load print media; one a direct front loading path that can handle poster board 1.5 mm thick.
Prints resolutions are 2880 x 1440 dpi, 1440 x 720 dpi, 720 x 720 dpi, 720 x 360 dpi, 360 x 360 dpi or 360 x 180 dpi. The first major maintenance is due after 45,000 8 x 10 inch prints at 720 x 720 dpi, 29,500 prints at 1440 x 720 dpi, or 15,200 prints at 2880 x 1440 dpi - likely to be a lengthly interval. If printing is done solely in unidirectional mode, the print quantity before maintenance is halved.
There are 180 nozzles per ink tank channel, which can deliver three sizes of droplets within a print line, down to 3.5 picoliter droplets delivered through control curvature of the nozzle. Eight ink tanks hold either 110 ml or 220 ml cartridges of three different blacks; Black, Light Black, and Light Light Black, with black available as either photo black or matte black. Colors are cyan, light cyan, magenta, light magenta and yellow.
The ink tanks are stationary, with channels that feed to the print head. Each ink cartridge is chipped, allowing your PC to track ink usage and let you know when a cartridge needs replacing. Both 110 ml and 220 ml cartridges can be used simultaneously, allowing you to customize the cartridges based on expected color use. A sensor cleans the print head automatically when needed, even clearing partially clogged printer nozzles.
The printer holds up to 250 sheets of plain paper or 50 sheets of letter to 17 x 22 inch photo paper. It can print on both sides of a sheet without damaging the other side, and the prints are moved through the printer by fans, not rollers, eliminating roller marks from prints. The fans do add considerably to the loudness of printing.
On roll media, it can produce left and right side borderless prints up to 17 inches wide. Roll media can be on 2 or 3 inch cores, and up to 132 feet in length. The Epson Stylus Pro 4800 can print to varied lengths on roll media, depending on the OS, application, and RIP or driver used.
Epson Stylus Pro Model printers are manufactured differently than the rest of Epson's printers. Instead of being put together on an assembly line, they are built singly, and then each individual printer goes through colormetric calibration, which is then burned to ROM, so colors are completely consistent from printer to printer.
