GENERAL SPECIFICATIONS

1.1

Print Specifications

(1) Print speed
 The maximum is 100 mm/s {3.94"/s} when printing ladder bar codes, 2-dimensional symbols, or multi-tone
graphics.
 The print speed changes automatically depending on the voltage applied to the printer and the condition of the
head temperature.
 Maximum print speed may not be achieved depending on the data transmission conditions and the combination
of commands.
 If the print speed fluctuates or intermittent printing occurs due to the data transmission conditions, printing
may be shaded or white lines may occur.
(2) Multi-tone graphics printing and limitations
 Multi-tone graphics printing is possible (up to 16 tones when using our specified paper).
 Multi-tone printing is not supported in Page mode.
 Voids (white spaces) may appear depending on the paper type (uneven application of chromogenic coating).
 It may not be possible to recreate an original image because a certain density level cannot be achieved due to the
following causes:
 Environmental temperature, power supply and voltage
 Paper type (chromogenic characteristics)
 Paper variations, such as variations among manufacturing lots
 Printing pattern (effect of heat accumulation of the print head or of voltage drop/speed change due to high
duty)
 For multi-tone printing, the preservative quality of materials printed using multi-tone printing decreases in
direct relationship with the lighter the printing. Accordingly, do not use multi-tone printing when preservative
quality is required.
 Reading quality of bar codes/2-dimensional symbols in multi-tone graphics printing is not guaranteed.

Character Specifications

 Can be changed via the software settings.
 For details, see 3.8.3 Software setting mode.
1.3

Autocutter

 The cut paper may be pulled at the cut edge when it is removed, causing reduced printing pitch for the first line
of the next receipt.
To prevent dot displacement, after cutting, feed the paper approximately 1 mm {16/406"} or more before the first
line of printing. This operation can be enabled by enabling the pre-feed before next print, or by setting the top
margin specification via backfeed to 8.5 to 2 mm.
For the setting method, see 3.5.2. Software setting.
 When issuing paper whose vertical length is short, ensure at least 20 mm.
