|The POWER indicator does not light||
The printer is receiving no power. If you are using AC or DC power, make sure that the AC adapter or DC cable is properly connected (See "How to connect to an AC power outlet (Optional)" or "How to connect to a DC power outlet (Optional)".) and make sure that the AC or DC power outlet is turned on. If you are using DC power, check the fuse.
|No rechargeable Ni-MH battery found when charging||
The printer did not detect a rechargeable Ni-MH battery when you tried to charge the battery.
If the rechargeable Ni-MH battery is connected properly, the battery may have overheated while charging. Allow the rechargeable Ni-MH battery to cool before charging it again. If this is a reoccurring problem, replace the rechargeable Ni-MH battery.
|Time-out when charging the rechargeable Ni-MH battery||Too much time is needed to charge the rechargeable Ni-MH battery (normally the battery should be fully-charged within 120 minutes). Replace the rechargeable Ni-MH battery.|
|Head or motor is cooling down||
The thermal head or motor is too hot.
This condition may occur more often when the printer is used at high altitude (more than 10,000 feet) due to a lower air density available to cool the printer.
|Data reception error||
Data is not being received properly, most likely because of a poor IrDA connection. Reposition the printer and/or IrDA port on the computer and try again.
|Buffer full or format error|
|Printer is in boot mode||
The AC adapter was unplugged while the firmware was being updated, and the printer started up in boot mode the next time it was started. Contact your reseller or Brother Customer Service for assistance.
