Table 2.3-1 Recommended thermal paper model
2.3.2 Parameters of marked paper
T-40 can support marked paper printing and set the cutting and initial printing position
accurately. The marked paper not only should meet the specifications of thermal paper roll, but
also should meet the following requirements:
ØL1 mark height: 3 mm≤L1≤13 mm
ØL2 mark length: L2≥8mm
ØL3 distance between two marks: 30 mm≤L3<450 mm
ØThermal side mark sensor position: reserved the left/middle/right positions
ØNon-thermal side mark sensor position: the middle/left/right position is selectable
ØReflectivity: The reflectivity of the black mark must be no more than 15% while the reflectivity
of the paper itself should exceed 85%. There should be no image between the two marks,
such as the advertisement, etc.
Caution:
²Please use the recommended paper or its equivalents. Using the paper of low quality might
affect the print quality and shorten the lifetime of print head;
²Do not stick paper onto the core shaft;
²If the paper is contaminated by chemical or oil, it may discolor or lose heat sensitivity at the
polluted spot, which will affect the print affect;
²Do not rub the paper surface with hard objects, otherwise it may affect the print affect;
²When the environment temperature goes up to 70℃, paper will discolor. Thus don not use or
store paper under high temperature, high humidity and strong light conditions.
²The mark is measured during printing and paper feeding. If the mark height value detected
by the sensor is bigger than the default value (default setting is 13mm), the printer will alarm
paper end.

The following diameter of core shaft of paper roll supported by the printer are as following: OD
of 16.2mm core shaft and OD of 20.8 mm core shaft; adjust the paper near end sensor to adjust
the application method and paper near end alarm function for core shaft with different outer
diameters. There are four positions indicated by the scale marks for paper near end alarm, and
users can rotate the paper near end adjustment spanner to make the indication line locate at
different position, which change the paper near end alarm functions under different application
conditions. The position 1 and 2 are for the application that output paper from the top, position
1 is for 16.2 mm core shaft of paper roll and position 2 is for 20.8 mm core shaft of paper roll.
The position 3 and 4 are for the application that output paper from the front, position 3 is for
20.8 mm core shaft of paper roll and position 4 is for 16.2 mm core shaft of paper roll.

²H stands for the host and P stands for the printer;
²The letter “n” in front of signal name indicates that the low level is effective;
²In data transmission, the host should not ignore “Busy” signal; otherwise print data may be
missing;
²If the host cannot provide all the signal lines listed in the table above, the communication
may fail;
²Parallel interface signal adopts TTL level; the rise and fall time of the signal from the host
must be controlled within 0.5s when it is used;
²For the interface, the signal line should use twisted pair with feeder line end, with the
feeder line end connected to signal ground;
²The parallel interface connecting wire should be as short as possible on condition that it
meets the use condition.
