Needle counter
For every needle there are two 16-bit counters (normal counter and backup counter),
which are incremented alternatively every 40000 needle firings. If a counter has rea-
ched the value of 32000, it will no longer be increased, because in this case the ma-
ximum number of write cycles for the Eeprom has been reached.
Status printout of the printhead chip
By pressing the keys "Online" + "Setup" during power on you can print out the con-
tents of the printhead chip. The first two values of one line are the coil parameters in
mV and m? as before. If a parameter is out of tolerance (17.3 ± 20%), then it is mar-
ked as invalid with an asterisk ("*") after “m
Ω
” and the display will show "THS
ERROR". The parameters named "Dot" and "Edot" are the two needle counters (one
increment = 40000 needle firings), "Stat" identifies the status of the counter. "Stat"
has the following meaning:
