Installing the Printer
You must install this printer vertically (with the paper exit at the front).
If the paper exit is blocked by label backing paper accumulating on a table or other surface,
a paper jam or other problem may occur. Install the printer in a location, such as at the
edge of a counter, where the backing paper will not accumulate near the paper exit.
CAUTION:
Never install the printer in locations that receive direct sunlight. The diffuse
reflection from the roll paper may cause the label peeler detector to malfunction.
Note:
You can install it either on a flat surface, or you can hang it on a wall by using the
optional bracket (WH-10).
To hang the printer on the wall, see the Wall Hanging Bracket Set Installation
Manual provided with the WH-10 for instructions.
WARNING:
When hanging the printer on the wall with the hanging bracket set, be
sure to attach a connector cover to the printer.

(You can still use widths from 38 mm to 60 mm with the roll paper spacer with the tabs
broken off) Follow the steps below to attach the roll paper spacer.
1. Pull the peeler open lever forward and open the peeler cover.
2. Pull the roll paper cover open lever forward, and open the roll paper cover.

Note:
When you want to set the roll paper width from 61 mm to 70 mm, break off by
hand the two tabs of the spacer. (You can still also use widths from 38 mm to
60 mm with the spacer with the tabs broken off.)

6. Pull out the paper until the end exactly reaches the guideline.
Note:
Making sure the paper end is at the guideline reduces the number of labels
required for detecting the minimum paper length. The number of labels issued
depends on the length of the label, but 2 labels are issued when the length of the
label is less than 50 mm {2"}, and 1 label is issued when it is 50 mm {2"} or
more.
7. Eliminate any slack in the roll paper, and then close the roll paper cover.
Make sure to close it firmly, pressing both ends.
8. After the paper is automatically fed and the first label comes out, the PAPER OUT
LED starts flashing.

flashing. Pulling it before that may result in the waste of a label.
Do not block the label peeler detector with your fingers, or anything else while the
label issuing is in progress. This may cause the printer to feed the following label.
CAUTION:
When installing roll paper, be careful not to injure your hands on the manual
cutter.

maintain receipt print quality.
1. Turn off the printer, open the peeler cover, and then the roll paper cover.
2. Clean the thermal element of the print head with a cotton swab lightly moistened with
an alcohol solvent (ethanol or IPA).

Cleaning the Peeler Unit
After the peeler is used for a prolonged period of time, the glue from the labels accumulates
on the rollers of the peeler unit. If you leave the rollers in such a condition, the glue may
stick to issued labels, or a paper jam may occur. To prevent malfunctions and maintain
good print quality, clean the rollers regularly (every 100,000 labels).
You can clean them easily if you use a wasted label.
Note:
Do not use any alcohol based solvents for cleaning. Such solvents may enter the
roller shaft and cause a malfunction of the peeler.

Troubleshooting
ERROR LED is on or flashing
❏Make sure that the roll paper cover is closed and the PAPER OUT LED is not on.
Close the cover or replace the paper if necessary.
❏If the printer has been printing a lot and the print head gets too hot, the ERROR LED
starts flashing, and printing stops. When its temperature cools down to the normal
range, printing resumes automatically.
❏Turn off the printer and then turn it back on. If the LED is still flashing, consult with
your supervisor or a service person.
PAPER OUT LED is flashing
If the PAPER OUT LED continues to flash even after the issued label is removed, the label
peeler detector may be detecting something. Press the PAPER FEED button once.
Paper jam
Turn off the power, open the peeler cover, and then open the roll paper cover to check for
a paper jam. If there is a paper jam, remove the jammed paper and follow the instructions
in the Installing Roll Paper section to prepare the printer for printing.
