STATUS Lamp

FEED Button

The [FEED] button operates as FEED button or PAUSE button depending on the printer statuses.

As the FEED button

As the PAUSE button

Pressing this button when the printer is in online state causes a media feed. Pressing this button after removing a cause of an error returns the printer to online state.

Pressing this button during printing stops printing after completing the current label. The printer resumes printing when this button is pressed again.

The indicator lamp lights up or flashes in different colors depending on the printer statuses. The main indicator lamp statuses and the corresponding printer statuses are shown inside the top cover.

	Color	Status	Printer status
	Green	Lights up	Stand-by
	Green	Flashes fast	Communicating with a host.
	Green	Flashes slowly	Printing is temporarily stopped (paused).
	Green/Red	Flashes slowly	The print head temperature exceeded the upper limit.
	Red	Lights up	A communication error occurred. (Only when the RS-232C is used.)
	Red	Flashes fast	A paper jam occurred.

NOTES:

EO18-33025

1.5 Supply Specifications

1.To ensure print quality and print head life use only TOSHIBA TEC approved media.

2.When using a media roll of 76.2-mm (3”) inner core diameter, the 3”-Diameter Media Shaft included in the optional External Media Roll Hanger is required.

3.Precaution for use of labels

When labels are used for printing, please only use outside wound labels. Use of an inside wound label causes a paper jam.

	Outside wound	Inside wound
Label	Usable	Not usable
Tag Paper	Usable	Usable

1.5.2 Detection Area of the Transmissive Sensor

The Transmissive sensor is fixed and positioned at 6.35 mm right of the center of the media path. The Transmissive Sensor detects a gap between labels, as illustrated below.

NOTES:

1.Be sure not to print on the 1.5-mm wide area from the media edges (shaded area in the above figure).

2.The centre of media should be positioned at the centre of the print head.

3.Print quality is not guaranteed within 3 mm from the print head stop position (including 1-mm slow-up.)

4.Average print (black) rate should be 15% or less. For bar code print area, the print rate should be 30% or less.

5.Line weight should be 3 to 12 dots.

1.5.4 Ribbon

Type	Spool type
Width	33.8 mm to 110 mm
Length	Depends on its thickness and outside diameter of core.
Max. outside diameter	40 mm
Inside diameter of core	12.7 mm
Roll direction	Outside

NOTES:

1.To ensure print quality and print head life use only TOSHIBA TEC specified ribbons.

2.Too much difference in width between media and ribbon may cause ribbon wrinkles. To avoid ribbon wrinkles use a ribbon for proper media width shown in the above table. Do not use a ribbon that is narrower than media.

3.When discarding ribbons, please follow the local rule.
