3. TROUBLESHOOTING

3.1 Error Indication

Paper end Paper out is detected in two steps: paper near-end and paper end. ERROR LED will light when the paper is empty. If paper end is detected, refill the paper. If the printer cover is open, a paper-end is detected.

Cover open

During printing, do not open the platen. If you open the printer cover accidentally, the ERROR LED blinks. Check the paper, pull the paper straightforward several cm (or inches) out of the printer, and then close the Platen. Printing resumes automatically. Sending a command to resume printing may be required depending on the memory switch setting.

Thermal head overheat

When you print dense characters or dark image, the head temperature rises. If the head temperature exceeds a specified level, the printer stops printing operation and waits till the head temperature is lowered. During waiting, the ERROR LED blinks. When the head temperature is lowered, printing resumes automatically.

Cutter lock

If the cutter blade stops operating due to paper jam or the like, the ERROR LED blinks. Remove the cause of the trouble and press the FEED button. If the blade still does not move and the printer cover cannot be opened, do not open the paper cover forcibly. Open Cutter Gear Cover and turn Cutter Gear under the protection seat in the direction of arrow.

When you find that both ends of the blade reached the lowest position, stop turning the screwdriver. Open the cover and follow the procedure of removing jam or other cause of trouble.

3.2 Troubleshooting Procedure

When a trouble occurs, confirm its phenomenon, locate a defective part in accordance with “2.2 Troubleshooting Guide”, and troubleshoot as described below.

Phenomenon Find a trouble phenomenon in this column. If there are multiple phenomena, take all the corresponding items into consideration to locate hidden defective parts.

Cause Lists as many possible causes as possible. Guess a trouble cause out of them and take its check method to specify the trouble cause.

Check Method Describes a check method to specify a trouble cause.

Remedy Troubleshoot by taking a remedy described in this column. By troubleshooting in accordance with the above-mentioned procedure, you can troubleshoot efficiently with fewer misjudgments. 3.3 Troubleshooting Guide

• Power Supply Failure

Phenomenon Cause Check Method Remedy

The AC cable is not connected.

— Connect AC cable. No power (POWER lamp not illuminated) The fuse is gone. Check whether the

specified fuse is used. Use the specified fuse.

Faulty control PCB assy — Replace the control PCB assy.

The fuse immediately goes again after replacing with a new one. The circuit drive power is

abnormal. Use instruments such as tester to measure circuit driving voltage.

Replace the control PCB assy.

* If the fuse is gone with the specified AC adapter used, it is likely that the thermal head unit or control PCB

assy is defective. Replace either defective one. Check wiring for drawer cable and interface cable.


-21-

• Printing failure



Failed contact/connection of thermal head connector

Check contact/connection condition.

Re-insert thermal head connector.

No printing

Faulty thermal head — Replace the thermal head.

Check whether the paper being used meets the specification.

Replace it with the specified paper.

Faint printout or uneven printout

Faulty mounting of the platen roller

Check mounting condition of the platen roller.

Mount the platen roller properly.


-22-

• Paper feed failure

Use within specified voltage range.


Faulty mounting of the platen roller

Check mounting condition of the platen roller.

Mount the platen roller properly.

Paper feed failure Check that no paper is jammed, torn or caught in the paper path.

Remove unnecessary paper and set correctly.

Paper is not fed or jammed.

Foreign substance in the gear or broken gear

Remove the gear holder and check for any foreign substance caught in the gears or any breakage of the gears.

Eliminate the foreign substance. If the gear is broken, replace it with new one.

• Faulty sensor


Faulty paper sensor Replace the SA SUB PWB PE SENSOR.

Faulty paper near-end sensor

Check whether the ERROR LED flickers if paper expires. Replace the SA PNE

SENSOR. Foreign substance is attached to the paper sensor

Check whether any foreign substances are adhered to the paper sensor.

Remove the foreign substance.

Failed detection of paper feed Failed detection of paper’s near-end

Faulty connection of the paper sensor connector

Check the connector connection.


• Faulty auto cutter


Faulty connection of the auto cutter connector

Check the connecting condition of the auto cutter connector.


Failure in auto-cutter’s main unit

Use tester or oscilloscope or other instrument to measure supply voltage.

If the supply voltage is normal, replace the auto cutter.

No operation of auto-cutter

Paper feed failure (Paper jam)

Check that no paper is jammed, torn or caught in the paper path.

Remove unnecessary paper and set correctly.
