(Note 2) When the PE detecting function is neglected by the use of software, printing can be con-
tinued even if the NO PAPER indicator is lit. For normal operation, actuate the PE safety
function, in order to prevent breakdown.
• Self-diagnosis function (incremental printing)
When power is turned on while the line feed switch is pressed, the self-diagnosis routine will be
actuated to print all characters sequentially. If it is desired to stop this function, turn off power.
When self-diagnosis function
is
utilized, use paper with a width of 15 in. Otherwise, printing will be
made outside the paper, causing breakdown of the head.
• Override function
When the ON/OFF LINE switch is pressed in PE condition, SELECT condition will emerge, cancel-
ling PE and reading data for one line. After printing, OFF-LINE will be selected again. This function
can be effectively utilized when paper sheets are used, provided that ROM unit MZ-8BP4R or
MZ-8SR4R is employed.
