the system mode has the following functions for the printer self-test and setting various parameters.
(for details, refer to key operation specification.)
(1) self-test
· maintenance counter, printing various parameters
· automatic self-test
· head broken dots check
(2) setting various parameters
· feed fine adjustment (± 50.0 mm)
· cut position fine adjustment (± 50.0 mm)
(or strip position fine adjustment)
· back feed fine adjustment (± 9.5 mm)
· x-coordinate fine adjustment (± 99.5 mm)
· print density fine adjustment (thermal transfer: ± 10, direct thermal: ± 10)
· type of character code (pc-850, pc-8)
· selection of 0 font (without slash mark [0], with slash mark [0])
· type of control code automatic selection
manual selection (esc, lf, nul method)
manual selection ( {, |, } method)
code designation (manual method)
· type of ribbon (transmissive ribbon, non-transmissive ribbon)
· ribbon motor drive voltage fine adjustment (-15 ~ 0 step)
· strip status selection (not selected/selected)
· stacker use selection (for the b-372/572 only)
· reflective sensor manual threshold fine adjustment setting: (0.0 to 4.0 v)
· transmissive sensor manual threshold fine adjustment setting: (0.0 to 4.0 v)
· kanji code selection (type 1, type 2)
· euro code (new currency symbol) setting (20h to ffh)
· head type selection (only for the b-672 and the b-872)
· ready/busy control protocol selection (dtr protocol, rts protocol)
· reset process when the input . prime signal is on (on: performed, off: not performed)
(3) test print
(4) sensor display/adjustment
· thermal head temperature sensor indication
· open-air temperature sensor indication
· reflective sensor indication/adjustment
· transmissive sensor indication/adjustment
(5) ram clear
· maintenance counter clear
· parameter clear
(6) initial values after ram clear
① initial values after maintenance counter clear

② initial values after parameter clear

the total label distance covered, sensor adjustment values (system mode [4]), and data of the flash card are not cleared by ram clear.
2. the stacker is available only for the b-372 and the b-572.
3. the head type can be selected only for the b-672 and the b-872.

4. if “3: transmissive sensor (when using preprinted labels)” or “4: reflective sensor (when using a manual threshold value)” is selected for the type of sensor for a label issue when a parameter clear is performed, the threshold setting should be made again.
