4.7 Error Indication

●Paper end

Paper empty is detected in two steps: paper near-end and paper end. It causes the ERROR lamp to light. If paper end is detected, refill the paper. If the paper cover is open, a paper-end is detected.

●Paper cover open

During printing, do not open the paper cover. If you open the paper cover accidentally, the ERROR lamp blinks. Confirm the paper and close the over. Printing resumes automatically.

●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 lamp 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 lamp blinks. Remove the cause of the trouble and press the FEED switch. If the blade does not move and the cover does not open yet even in the above procedure, follow the procedure in section 4.4 to open the paper cover.

●Black Mark detection error (in Black Mark mode)

When no Black Mark can be detected even if a certain amount of paper feed is carried out for Black mark detection, a Black Mark detection error occurs. If black detection continues more than the specified period, a No Paper condition is assumed and the same error as No Paper is indicated.

Lighting and blinking status of each error including the above is shown below.
