TM and BM are fixed to 20 mm in front manual feeding.
The printer detects the paper width when paper is set. (If the paper width detection setting is OFF, the printer does not detect the paper width.) The printer does not print the image exceeding the detected paper width and the printable area that is specified in the paper setting. (If the paper width detection setting is OFF, the printer may print on the platen.) The top/bottom/left/right margins (TM, BM, LM, RM) can be set to zero under special conditions. Because the printer detects tilt of loaded paper in a range of 3 mm at both left and right sides, an image bleeds off both left and right edges of paper by 3 mm each at borderless printing. However, if the distance between the paper edges and the platen (sponge width) is less than 3 mm, the bleeding margins are adjusted to less than 3 mm (within the range of 0 mm a 3 mm) not to directly print on the platen. (Refer to "1.4.2 Borderless Printing" (p17), for the borderless print specification.)

This section explains the basic specifications of the print head. NOZZLE CONFIGURATION AND COLORS This printer is equipped with an MACH print head, which employs 180 nozzles per color. The printer ejects nine different colors of ink through the eight rows of nozzles. One of the rows is shared by Photo Black and Matte Black inks. The nozzle configuration as seen from behind the print head is shown below. Printing method: On-demand ink-jet Nozzle configuration: 180 nozzles x 8 rows = 1440 nozzles

2.3.1 Ink Flow Path
The ink flow path is shown below.
2.3.2 Ink Pressurizing Mechanism
This printer employs an ink pressurizing mechanism to stably supply ink in the ink cartridge (ink pack) to the print head. This ink pressurizing mechanism consists of a pressure pump unit installed in an ink supply mechanism and tightly-sealed ink cartridges. Air pumped into the tightly-sealed ink cartridge from the pressure pump unit squashes the ink pack in the cartridge, causing the ink inside the pack to be transferred to the print head.
