• Selectors 3 and 4: Enabling/disabling the head-platen gap offset settings (made by selectors 1
and 2 on AMS02 and selector 6 on AMS05)
These selectors specify whether to enable or disable the head-platen gap offset settings
made by selectors 1 and 2 on AMS02 and selector 6 on AMS05, depending upon whether
borderless printing is disabled or enabled.
The combination of selectors 1 and 2 on AMS02 and selectors 3, 4 and 6 on AMS05
provides 12 types of settings (see the following pages) for preventing stains from being
produced due to paper friction against the print head in high-duty printing.
• Selector 5: Reduction of occurrences of paper jams
Enable this function when paper jams occur. This function reduces occurrences of paper
jams by slowing down the paper feeding speed. It is effective only for plain paper.
• Selector 6: Head-platen gap offset for prevention of stains on recording paper (For A3, B4, and
ledger-sized plain paper)
If using A3, B4, or ledger-sized plain paper results in a stained print face due to warped
paper, increase the gap between the head nozzles and the platen with this selector to reduce
stains.
If this function is enabled, the machine prints unidirectionally.
Selectors 3 and 4 on AMS05 specifies whether to enable or disable the settings made here
when borderless printing is enabled or disabled. By default, the head-platen gap offset
function is enabled only when borderless printing is disabled. For the head-platen gap
offset for glossy paper or small-sized plain paper, see selectors 1 and 2 on AMS02.
