FEED Button
The [FEED] button operates as FEED button or PAUSE button depending on the printer statuses.
Pressing this button when the printer is in online state causes a media feed.
As the FEED button
As the PAUSE button
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.
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.

NOTES:
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.

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.

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.

!
(Revision Date: Mar. 27, 2009)
3.1 Replacing the Top Cover
3. REPLACING THE IMPORTANT PARTS
1. Turn off the power switch and disconnect the DC plug of the AC Adapter and the
RS-232C cable before replacing any parts.
2. Follow all manual instructions. Failure to do so could create safety hazards such as
fire or electrocution.
CAUTION!
1. To protect the connector pins or component from static discharge, do not touch them
with bear hand.
2. Use electrostatic free form and the original carton for transportation.
3. Keep your work environment static free to avoid damage to the printer.
4. Do not remove any connectors from the printer within 10 sec. after unplugging the
power cord.
WARNING
NOTES:
1. Manual instructions must be followed when installing option kits or adding cables to
avoid system failures and to insure proper performance and operation.
2. Failure to follow manual instructions or any unauthorized modifications, substitution or
change to this product will void the limited product warranty.
Lubrication
CAUTION!
1. Lubrication: During parts replacement
2. Kinds of oil: FLOIL G-488: 1kg can (part No.: 19454906001)
Any machine is generally in its best condition when delivered; therefore, it is necessary to try to
keep this condition. Unexpected failure occurs due to lack of oil, debris, or dust. To keep its
best condition, periodically clean the machine and apply proper kinds of oil to each part in
which lubrication is needed. Although the frequency of lubrication varies according to how
much the machine is used, at least it is necessary to lubricate before the machine becomes dry.
It is also necessary to wipe off excessive oil as it collects dirt.
NOTE: Before replacing the important parts, store the printer parameter data on a PC with the B-EV4
setting tool. Uploading the data from the PC to the printer after replacement restores the
printer parameter setting to the status prior to replacement. Regarding the details of B-EV4
setting tool, refer to the B-EV4 Setting Tool Specification posted on the Barcode Knowledge Pot.
