Notes when the printer is used with the MICR reader:
- When the printer recovers from an error using DLE ENQ 1, and the MICR function is selected
using FS a 0, the printer clears the print buffer, ejects the slip paper completely, and goes into
the roll paper mode. Therefore, when personal check reading is to be continued, select the
MICR function again using FS a 0.
- When the printer recovers from an error using DLE ENQ 2, and the MICR function is selected
using FS a 0, the printer clears the receive and print buffers, ejects the slip completely, and
goes into the roll paper mode. Therefore, when check reading is to be continued, select the
MICR function again using FS a 0.
- DLE ENQ 3 is ignored, except when the printer is in the slip or personal check waiting state
using DLE EOT 5 before executing DLE ENQ 3. Or be sure to confirm whether MICR function
is selected and the printer is in the personal check waiting state using DEL EOT BS 1. After the
printer is released from the slip or personal check waiting state, receipt and journal papers are
selected.
- This command is ignored while the printer transmits the reading results of MICR.
