The printer has the following protective mechanisms to detect overheating:

1.Overheat detection when replacing cartridge

If overheating is detected, a beeper sounds four times and the carriage does not return to the replacement position. This is to prevent the user from touching the BJ cartridge's metal plate.

Resume the cartridge replacement after leaving the cartridge to cool for several minutes.

2.Overheat detection during normal printing

The carriage movement and the paper eject operation are continued while the printing is stopped. Depending on the outcome of the ink-out detection after completion of printing a page, a beeper sounds to indicate the status of the error.

Ink available: BJ cartridge overheat error (beeper sounds 7 times)

Ink out: Ink-out error (beeper sounds 3 or 4 times)

When a BJ cartridge overheat error occurs, leave the cartridge to cool for several minutes then press the RESUME button.

These protective mechanisms are based on the temperatures detected by the sensors in the BJ head.

If the protective mechanism is activated and normal operation cannot be resumed after cooling the head for several minutes, see "Part 5: 6. TROUBLESHOOTING" (page 5-13).

For details of ink-out detection, see "Part 4: 5.2.3 Ink-out detection" (page 4-48).
