The paper can be unloaded in two ways.

Move the head up lever toward 

: Head up position and then pull

the paper out by hand in the forward direction (feeding direction)
or in the reverse direction.

Operate the paper feed mechanism to discharge the paper from
the printer. Move the head up lever to the head up position 

 and

remove the paper toward the front.

(Notes)

•

Operations other than those listed above could cause im-
proper paper feeding and jamming, and could cause
breaking of the head heating elements.

•

Never pull the paper out without using the head up lever,
regardless of the direction, forward or reverse.

If a paper jam occurs, follow the procedure below.

Put the head-up lever in the 

 Cleaning position to widen the

spacing between the head and platen rollers so that you can
easily check for a paper jam.

Remove a jammed paper by hand.

Return the head-up lever in the 

 Close position.

When a tool such as tweezers, is used to remove paper chips, take
care not to touch the heating elements of the head with the tool.
Since the head is still hot just after the operation printing is stopped,
wait a while for the head to cool down.

If the autocutter is slow at operating or stops due to a paper jam,
remove the cause orf the problem according to the following proce-
dure:

Procedure for releasing the lock

Turn off the power switches on the printer and the cutter section.

Do not carry out this procedure while the power switches are
on.

Open the autocutter device.

Fig. Opening the autocutter device

A slit for turning the motor shaft gear is provided in the autocutter
cabinet.  Insert a small phillips screwdriver through this slit and
turn the motor shaft gear.  The cutter blade will move so that you
can remove the jammed paper.

Fig. Releasing the paper jam lock

After removing the jammed paper, remove any small piece of
paper around the autocutter.

To maintain proper performance of the printer for a long period of
time and to prevent trouble, carry out the maintenance and manage-
ment procedures as follows.

•

Removing stains
Wipe dirt off the head and platen rollers with a clean cloth satu-
rated with an alcoholic solvent (ethanol, methanol, IPA: Isopropyl
alcohol).
For cleaning the head part, refer to daily checks.

(Notes) Never use thinner, benzine, trichlene or ketone group sol-

vents, since they may damage or deteriorate rubber and
plastic parts.

•

Removing dust and fuzz
Cleaning by suction (with a vacuum cleaner) is desirable.
Suck up all the dust and fuzz.

(Notes) Check lubrication at various points after cleaning, and lubri-

cate with oil at the specified locations.

The maintenance and inspection items for the printer are dividend
into 2 types. One is "Daily checks" for the person who uses the
printer, and the other is "Periodic checks" for someone with more
technical knowledge. Maintenance and inspections should be carried
out by properly qualified personnel.

Check that the printer is used properly and kept in the good repair. 

The specified paper is being used.

The paper has not become discolored.

Check print quality and if significant deterioration is found, clean
the head heating elements.
