Unless the power is switched OFF, then ON again, the HALT state cannot be released. Even if the power is switched ON again, the printer
will remain HAL Ted until the cause of the halt is removed.
The drum rotation start command is accepted only when the printer is READY (RDY is TRUE). If RDY is FALSE, the command is
ignored.
The PAUSE command is acknowledged anytime except when the printer is initially reset. The printer can, however, switch to PAUSE only
if the printer is in WAIT or STBY.
When the DC controller receives a TRUE PRNTsignal, the DC controller transmits a TRUE VERTICAL SYNC REQUEST signal (VSREQ)
to the external device. If the external device PRNT FALSE before transmitting the VERTICAL SYNC signal (VSYNC) to the DC
controller, the printer starts LSTR.
If the pickup sensor (PS1) detects paper during STBY in cassette feed, RDY becomes FALSE and the paper is delivered. If PS1 does not
detect paper, RDY becomes TRUE again.
