Low Battery Warning
When the battery is low, a low battery warning is issued (See the "Diagnosis Chart" section). If
printing of the page is not finished yet, you can either:
Connect the printer to an AC outlet. Then press the ON LINE switch to resume printing.
If AC outlet is not available, you can use the remaining battery power for limited printing.
Pressing the ON LINE switch each time prints several lines, until the battery pack is totally
exhausted; then a low battery error is issued.
Low Battery Error
When the battery pack is totally exhausted, a low battery error is issued (See the "Diagnosis
chart" section). Recharging is required before it can operate again. If you have work still in
printing, the only way to continue is to plug the printer into an AC outlet.
Caution
Replacing the battery pack at the middle of printing will result in loss of all data
still remaining in the printer buffer.
