2-3. Handling Care
1. Be careful not to drop paper clips, pins or other foreign matter into the unit
as these cause
2. Do not attempt to print when either paper or ribbon cartridge is not located
in the printer, otherwise the print head can be damaged.
Do not open the cover while printing.
3.
4. Do not touch the print head immediately aer printing as it gets very hot.
5. Use only roll paper that is not glued to the core.
6. When the paper end mark appears on the paper, replace the roll paper before
it runs out.
the printer to malfunction.

P
Make sure that the printer is turned o and unplugged from the AC outlet
and that the computer is turned o before making connections.
P
Do not connect a telephone line into the modular connector.
P
Do not pull out paper while the printer cover is closed.
P

2-4. Maintenance
Essentially, your printer is a robust piece of equipment, but should be treated
with a modicum of care in order to avoid malfunctions. For example:
Keep your printer in a “comfortable” environment. Roughly speaking, if you
1.
feel comfortable, then the environment is suitable for your printer.
Do not subject the printer to physical shocks or excessive vibration.
2.
3. Avoid over-dusty environments. Dust is the enemy of all precision
mechanical devices.
4.
To clean the exterior of the printer, use a cloth barely dampened with either
water with a little detergent or a little alcohol, but do not allow any liquid to
fall inside the printer.
5.
The interior of the printer may be cleaned with a small cleaner or a
compressed-air aerosol (sold for this purpose). When performing this
operation, be sure not to bend or damage any cable connections or electronic
components.

4-1. Installation of Ink Ribbon
(1) Turn power o, li the Printer Cover up and remove it.
Note: Be careful not to touch the print head immediately after printing,
because it can get very hot.
Figure 4-1. Printer Cover Removal
(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.
Hold the ribbon taut as shown with the drive pins facing down and slide the
ribbon between the print head and the platen. While keeping the ribbon
taut, wrap one side around the black ribbon guide on the end of the platen
and drop one spool on the spool sha. As you move the spool downwards,
move the detecting lever aside to allow the spool to drop into place. Make
sure the spool drive pins engage with the spool drive holes. As the spool
drops into place there will be a click.
(3) While continuing to hold the ribbon taut, install the remaining ribbon spool
in a similar fashion.
(4) Turn the spool that rotates freely to take up the ribbon slack.
