Indicator Warnings

Problem

Solution

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 Car adapter is properly connected (see Connecting

 

the Printer to External Power uu page 2) and make sure that

 

the AC or DC power outlet is turned on.

 

If you are using DC power, check the fuse.

 

 

Head or motor is cooling down

The thermal head or motor is too hot.

 

Head:

 

If the thermal head becomes even hotter, the thermal head may

 

produce imaging on the paper in areas not intended to be

 

printed. This condition is normal when printing documents with

 

a great deal of “black” content.

 

The printer will stop and resume printing after the print head

 

has cooled down.

 

To avoid or delay the onset of this condition, print using a lighter

 

density setting, reduce the amount of black space being printed

 

(for example, remove background shading and colors in graphs

 

and presentation documents), and make sure that the printer

 

has adequate ventilation and is not located in an enclosed

 

space.

 

Motor:

 

Do not use the printer continuously. If the printer is used

 

continuously, the motor will become too hot. In this case, the

 

printer will stop and resume printing after the motor has cooled

 

down.

 

Note

 

 

 

 

 

 

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 may not be received correctly when communications are

 

 

unstable.Try connecting again when communication conditions

 

 

have improved.

 

 

 

 

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.
